HP - New monitor or graphics card?


Recommended Posts

Hello. 

 

I have an HP Pavillion. Mom & Dad got it for me a couple of years ago for my birthday. One of those Walmart everything in a bundle. I'm not slighting that.

 

For various reasons, I didn't unbox and set it up until late last /early this year. 

 

She died in Feburary. Would not boot; dive would attempt to turn, and that was it. The technician said she was a good machine, but she'd needed two cleanouts, and it was obvious the cats had peed and sprayed where they shouldn't. She suggested getting the computer higher and turning it off and covering it with a towel when I wasn't using her. I missed the latter a few times, but thought I was doing well. Until this recent problem. 

 

I was playing in the Facebook Game Room, when suddenly, it was like a fog on the monitor. I could kind of see, but not clearly. Then the monitor went into different colored lines and test patterns. 

 

I think I finally hard rebooted, and things came up fine. Stayed that way for a few days, until this morning, when I turned the monitor on. Again with the fog, and the flashing, changing patterns. This time nothing has stopped them or cleared things up. 

 

I turn the monitor off a lot. I'm old school; I got my degrees with the old CRT monitors, where you don't want ghost images, etc. 

 

I've tried rebooting. I've tried unplugging and replugging power to the monitor. I've unplugged and plugged the computer cable on both ends. I've reset to factory settings, just in case the cats had goofed something. I tried to run HP's diagnostics, but I can't see well enough for that. I don't have another monitor to try, except an old CRT that will take a bit to get to. 

 

Is there something else I should try before a trip to the technician? Is there a way to tell what it's more likely to be, a monitor error or a graphics card problem? That's all I can think it could be. 

 

There is a chance that this could be a heat-caused problem. I've had trouble with that before. There's nowhere else to put the computer, though. 

 

I want to either fix the problem, or at least be able to discuss it intellgently. I have some pictures and a short video I took with my phone. I'll try attaching a couple of the shots. 

 

Thanks,

Theresa

You are in the right place for technical help and if you are patient, we can walk you through the steps required.

 

To start with, please provide the exact model number and the basic specs of the hardware along with O/S Version and the model number of the Monitor.

 

Morning :)

Thanks for the replies. You're fast!

 

+DevTech, I have to leave in about 5 minutes. I will find the box etc. after I get home tonight.  OS is Windows 10, that's as far as I can go off the top of my head. This year has been chaotic. 

 

I am leaning towards a monitor problem. I did a hard computer shutdown a minute ago because I won't be home today. Tried the monitor, it is still doing the same thing.

 

Corinthian, I'm not sure I have another cable. I may have from an older machine; I'm hard on computers. Have at least 4 dead ones in my closet right now; been hoping someday to get hard drives pulled and shelled to use.

 

Have a good day.

If the computer is turned off and the monitor is showing the same defects such as when trying to access the monitor's built-in menu etc then you can simply conclude:

 

1. The problem is NOT the computer.

 

2. With the computer turned off the cable goes nowhere and so it is NOT the cable.

 

3. Your monitor needs to be repaired or replaced. If you have a budget available, you could benefit from examining the list of monitor suggestions I provided in this post, (although gaining benefit requires NOT completely ignoring all sensible advice like the person in that thread):

 

 

4. There are hints in your description such as the Over-Heating, and Acid-Damage that you may have a SECOND set of problems with the computer itself and we can continue work on fixing that if you want after the monitor situation is resolved.

 

5. If you have some sort para-normal or supra-normal situation that delivers computers to their Ultimate Doom per the mass-grave in your closet, then you may have (or just your Digital Friends have) an OCP (Outside Context Problem) as sometimes encountered in the Culture series of novels by Ian M. Banks.

Thanks +Devtech 

Yes, I felt really stupid yesterday morning when I realized I hadn't tried shutting off the computer and checking. Probably wasn't a need to post at all, was there ?😡 at myself, I'm usually much more on the ball. 

 

I have to run Mom somewhere, will read the article while waiting on her. 

Wow. That Asus at Amazon is an eyeopener. I wish I had the $ and a good place for it. 

 

Thanks for the thread. I had not known about the panels. I will research today. 

 

Do you find that eye care is useful instead of just a selling gimmick? I wear glasses. I have to use them with the monitor I have now. I have to be careful both at home and at the library to watch my time and take regular breaks, otherwise I get sick. I don't have to use my glasses with cell phones.

 

As for the other, when we get back home, I'll clean up a bit and then post at least a picture so you can see what I have. 

 

Thanks,

Theresa

1. EyeCare/Blue Spectrum

 

it is a stupid gimic or not depending what you think about the science behind it. Building the feature into the monitor means that it is always available even when connecting other devices to the monitor. Other than that, you can add free utilities to Windows to do the same thing.

 

The idea is that during the middle of the day, there is more blue light in the spectrum and as sunset approaches, the blue part of the spectrum diminishes and along with other signals, life on Earth uses that to detect the day/night cycle. So if you use TV or computers or tablets late at night, the blue light coming from these devices could disrupt your sleep cycle.

 

Other than discontinuing the usage of modern electronics many hours before sleep, the devices themselves can be setup to gradually reduce the amount of blue spectrum to mimic what natural daylight does.

 

Many people have taken this concept to extremes and feel that the amount of BLUE in all devices should be reduced at all times.

 

Personally, I like a disrupted sleep cycle and HATE the idea that any device is not giving me 100% accurate color rendition at all times, so I would turn off any feature like that.

 

 

2. Glasses

 

You are not specifying if you have otherwise good vision (such as 20/20) and wear glasses specifically to combat nausea with electronic displays.

 

2.A) Resolution/Pixel Density - If you have a modern cell phone near the top end, it has a very high resolution display in a 6 inch size giving High Pixel Density that is a lot easier on the eyes than typical older computer monitors. The measurement is Dots Per Inch (DPI) or Pixels Per Inch (PPI) - same thing - and seeking out a computer monitor with high density could be a solution for you. Which means a 4K monitor in the smallest size you can find.

 

2.B) Refresh Rate - Some people are also bothered by the refresh rate of the monitor and using a high refresh rate can help but is harder to find in general than a standard refresh rate 4K monitor.

 

2.C) Evil Fluorescent Lighting - Some people are affected by the interference interaction between fluorescent lighting and the monitor refresh rate. This is actually quite common. The solution is to eliminate ALL fluorescent lighting in your environment. That means those 4 foot overhead bulbs and the compact fluorescents designed to replace normal light bulbs to save energy. REPLACE ALL OF THAT with LED lighting.

 

(Rant alert: Some people complain that they have no control in a workplace environment but I have yet to see a place that won't let workers pay for the replacement bulbs themselves to achieve better productivity. Although the workplace should pay, the overriding consideration is that the cost is a pittance compared to health.)

 

2.D) Glare - Some people don't pay attention to other light sources in the room reflecting off the monitor's surface in ways that can even lead to bad headaches. Turn off the monitor and pay careful attention to what light sorces you see reflected in the screen - cover or eliminate them or move the angle of the monitor.

 

2.E) Ambient Rear Lighting - To reduce eye strain, there should be a dim light source behind the monitor, similar in brightness to 1 or 2 "night lights" particularly if the monitor has a wall directly behind it. Of course a Window behind the monitor is the opposite problem and the monitor needs to be relocated so that theres is no window behind it (or in front of it re Glare)

 

 

Afternoon. 

 

Nuts about the eye care. I have heard about the blue light and have played with that little program, fmlight?, that's supposed to adjust based on time. I haven't seen much difference. I was hoping there was something different.

 

Based on the thread, I should mention that I have an extremely low budget right now. Barring a miracle,things will be fairly tight the next few months at least. I'm still going to check the panels and follow your other suggestions, I just don't want to go down the expensive rabbit hole and waste everyone's time. 

 

Glasses: I wear them often, can't really drive without them. I see better w/o them closer than far away. My right eye is much better than my left. I don't wear them just for monitor problems; it's a every day wear prescription. 

 

Density:  My phone is a Axia QS5509a. It's a 480x854 resolution. 

 

I had a Samsung Galaxy J7, but I misjudged my pocket and it got baptized last year. Works when it wants to, hence the Axia. I actually like the Axia better, less bloat. The Samsung was always complaining about memory, the Axia doesn't, though they are supposed to match at 16GB total. 

 

Lights: I have one bare bulb in my ceiling, which is behind and east of my desk. I bought an $11 desk lamp that is LED awhile back for paperwork and has a USB charger in it - one of those $11 from Walmarts. You'll see it in the picture. 

 

At almost 4 PM, there isn't any other reflections. But, as the room's door is slightly behind me and to the west, the hallway and bathroom lights can shine in at night. I'll have to wait until dark to check if any light falls from outside the windows, on the east wall. 

 

Would a rope light be ambient enough? I hadn't heard about lights behind the monitor. I used to have some cheap white rope lights;always thought they were pretty, but others teased me for them, claimed they were a fire hazard, etc. I may still have them. 

 

Have you seen the tiny fairy lights or the LED ropes that are used to frame the TVs, monitors, etc.? I'll be by a light fixture store Tuesday morning, and can see what they have. 

 

Thanks

Theresa

 

 

 

 

 

Here are pictures of my setup. I had the computer on a roller, but that wasn't high enough off the ground. My old dollbed came in handy. I took the wheels off the roller and set it all in the dollbed. 

 

Darn. Both of my pics are too big. Let me get pets and people taken care of and fed, and I'll take more. 

Here we go :). 

It's a regular setup, nothing drastic about it. 

 

Except a couple of my computers have died because of too much heat, the techs said. One worked fine at the shop after it died here one night. Never worked here again. And so on .....

That looks like a basement or garage workbench.

 

If you have enough room to the left or right on the "table" that would be a better place for the computer.

 

If you don't mind, it would help to know approximately where in the world you live, since Death By Heat is usually associated with places like Egypt etc. And your rough location would also give me an idea of what type of stores are available to you.

 

As a minor note, I have built all sorts of work surfaces over the years. Your work surface will be more pleasant if you painted it with cheap paint, or even glued photos or dyed flowers or whatever art would be fun and then the secret ingredient is to cover whatever you make with a high quality "Clearcoat" Polyurethane for which they have "single coat coverage" these days...

So, all our work will be to no avail if this happens again.

 

We need to add it to the problem list and nail it dead. Cooling down computers is the first thing a tech hobbyist plays with because they can't perform right of they are running hot. So lots of expertise here on cooling.

 

Again we need to get a picture of your ambient temperature. 

 

Also, you still have NOT provided the model number and specs of the computer.

 

And look in back of the monitor at the tag and provide the monitor model number as well.

Thanks for the info.

 

Your cell phone does NOT have high pixel density so that is NOT a factor in your eye strain issue.

 

If you have a local Dollar Store chain from China, you can buy a LED night light. Cover the light sensor with tape and it will turn on all the time with a 4 watt brightness.

 

The old rope lights used incandescent bulbs and could get hot and so they usually came with a warning for Outside Use Only. The modern equivalent is a LED Light Strip and those are way wacko fun and many come with a remote control!

 

Your #1 Priority is a new Monitor and we can advise you on specific models and even used models to fit any budget. Assuming you are really tight, a used Dell UltraSharp at 24 or 25 inches and a 1920 x 1200 resolution could look a lot nicer than most new monitors and is probably larger than what you have to reduce eye strain.

Oh good grief. Lets focus on finding a used or new monitor for the OP once we find out what stores are available.

 

There is a nice kind of non-esoteric roll up the sleeves hobby vibe to this set of interesting interlocking issues!

Oh. Sorry. I thought we were just focusing now on the monitor. 

 

Computer is an HP Pavilion 550-153wb. Monitor is a 23" full HD IPS LED Monitor. The back of the monitor doesn't have any stickers, but has HDMI and VGA and another other connector space. Sorry for the dust. 

 

Windows 10 home for the OS. 4th gen Intel core i3-4170 processor. 6GB DDR system memory. 1 TB hard drive. Integrated Bluetooth 4.0 and Wireless Lan. Intel HD graphics 4400, systems memory is used for graphics/video. (Ok, so I was lazy and did not go dig the box out to doublecheck before I first posted either.)  HP 7-in-one micro card reader. 

 

That's the basics from the box. I switched to a wireless keyboard and bought new $20 speakers. 

 

I've never had monitor problems before. This is my second one in totality. I had a big CRT for over a decade before it finally gave up the ghost. I don't recall having an instruction book, or anything aside from a page for putting the monitor together, and then the big foldout to get everything together correctly and in order. 

 

Yes, I'm in Missouri. SW corner of the state. Joplin is the closest town that is likely to be on a map. Carl Junction is a bedroom town a few miles away. 

 

If you're into the US Civil War, I drive by Radar's Farm quite a bit. Carthage isn't too far away, and Wilson's Creek is few minutes more. 

 

We've had crazy weather this year. It's been cooler than usual, we even had a frost/freeze warning the other night. Kansas City had snow and ice, they're about 4 hours north. Crazy. 

 

+DevTech, where at in the Ozarks? You were probably pretty close. 

 

Right now it's 9:30 at night. Depending on which one I'm checking, it's either 62 or 58 F outside. I have no idea what it is in here. I can find or get a thermometer if you'd like.

1. Monitor

 

- repair or replace

- I have started with a suggestion for low cost, we will see what you think of it and what your budget is

 

 

2. Sargasso of Dead Computers

 

- ok, so you live in a "temperate" climate i.e . NOT Death Valley, California.

- do you use air conditioning in the summer? if not, did your computers die in summer?

- describe the situations in which your current computer seems to overheat

- you mentioned Facebook Games - can you list the games you play? or better yet are any of them 3D?

 

 

3. Ozarks

 

- long time ago, not sure how I could find out, my Dad passed away, my Mom still alive but not the sort of thing she payed attention to...

- but I have strong memories and somewhere, even home movies!

    • I notice how you dodged the questions I had about the racism shown by ignorant, gullible, cowardly people when the Poles, like your partner, were the immigrants. Ahem. I wonder how you'd feel if native born Brits suddenly treated you as "dirty crooked immigrant" for being half Trump-American? If they ordered you to leave and "go back to your corrupt country" (on the other side of the Atlantic), would you go? The truth is based on facts as supported by evidence. As requested in your previous posts, I have used the facts in your own post to show everyone the truth.
    • US citizens are paying to their government, who could use that to fund healthcare and tuition and relieve the costs of these for citizens instead of making tax breaks that overwhelmingly favor the rich. I'm not saying that tariffs are the correct solution, but what else would they be used for? What else could Trump have in mind for wanting them, if he hasn't figured out that labor costs are higher in the US?
    • I’m in need of a new chair and it sounds like the backrest cannot be locked? I also sat on a Herman miller and was devastated that it couldn’t be locked also, what is going on with chairs. I want to be able to lock the backrest into any position but not even the Herman’s do that
    • Sihoo Doro C300 Pro V2 Ergonomic Office Chair review: The Ikea of chairs by Steven Parker I've reviewed a few gaming chairs over the past three years or so and generally found them to score well in our reviews. SIHOO reached out asking if I was interested in taking a look at their flagship chair, the Doro C300 Pro V2. I never got the chance to check out its predecessor, but the V2 is described as an "Adaptive Ergonomic Chair." It became available to buy in April of this year. Let's get things rolling with a closer look at the specifications and features. Specifications Doro C300 Pro V2 Model Ergonomic Materials Mesh Back and Seat; Soft PU Coated Armrests Height adjustability 45.5 - 53 cm / 17.5" - 20.9" Seat (w+d) 52 x 43 - 47 cm / 20.5" x 16.9" - 18.5" (adjustable) Backrest 52 – 60 cm / 20.5" - 23.6" (adjustable) Lumbar support Mesh built-in (adjustable) Armrest adjustability 8D Bionic Armrests Rocking angle 105°, 120°, 135° (fixed) Neck support Mesh built-in (adjustable) Net weight 27.3 kg / 59.64 lbs Weight support 150 kg / 330 lbs Colors Black, White Warranty 5 years (upon registering) Price $499.99, $539.99 Introduction At first glance, it looks like a chair that in another life wants to be a Herman Miller; It certainly looks like my Aeron Remastered, but the Doro C300 Pro V2 has quite a few more features and costs quite a bit less. SIHOO says that it is made up of a "DynaCore" system that tracks your movement and synchronizes the headrest, backrest, lumbar support, and armrests as you shift, twist, or recline. They also say that the "SyncroFlex Backrest" molds to your spine, which kind of describes how the mesh fabric works in most ergonomic chairs, but anyway. Below are the meat and potatoes measurements for the chair. Here is the same tech sheet, but in inches. Durability I would be remiss to not talk about the various durability testing this chair underwent before coming to market, as this is claimed on the product page. First of all, the chair is BIFMA-, SGS-, and TÜV-certified. As for durability, the tests undergone were: 100,000 Castor cycles tested 120,000 Armrest cycles tested 120,000 Recline cycles tested 120,000 Gas lift cycles tested 60,000 Armrest durability cycles tested 120,000 Rotation cycles tested Nothing about weights testing, though. Now that's all disclosed, now onto my own personal findings. Assembly The Doro C300 Pro V2 came in two large boxes (1) (2), and everything was packed very well, protecting the different parts of the chair. In the box, there is a folded sheet that explains the 12 steps to assemble it; they are: Remove the bottom cover on the aluminum base; Insert the five legs into the aluminum base and use ten screws to fasten them; Insert the castors into the legs; Replace the bottom cover on the bottom of the aluminum base; Place the Class 4 Hydraulics gas cylinder into the aluminum base; Screw the bottom part of the arm rests, taking care of the orientation using two screws on each side; Use three torx screws to fasten the footrest to the bottom of the seat; Fasten the backrest to the seat using four torx bolts; Fasten the armrests to the backrest using four Torx bolts (two on each side), taking care to note the orientation; Place the chair onto the Class 4 Hydraulics gas cylinder; Insert the headrest into the top of the backrest; Use two torx screws to fasten the headrest to the backrest. There's also an online guide you can refer to. Carefully unpacking the two boxes took around 15 minutes because almost everything is wrapped in plastic and protective foam; the chair assembly itself took around an hour. I say in the above assembly steps to take note of the orientation, because it's not obvious which way around the bottom portion of the armrests go, and although there is an L and R on the bottom of the armrests, it also wasn't clear from the instructions which was actually left or right, facing the chair, or in the seated down orientation? Anyway, I ended up putting the bottom portions on the wrong sides, and after securing one of the armrests, I discovered that although it was on the correct side, the armrest base could rotate a full 360°, but not when bolted to the chair, so I had to remove it, rotate it, and then bolt it back on. Truly an Ikea experience! Also, to complicate things further, although all the parts are labeled from A to X (yes, that's 24 parts) unhelpfully, these letters do not appear on the parts themselves or the package with the bolts, screws, and washers. There's also a pair of protective gloves in the box, but I think they were made for much smaller hands than I have. Even my friend, who is 5.1, had difficulty putting them on. Once assembled, I needed to sit down. Anyway, as I said, it looks quite similar to my Herman Miller. And here is the back of it. If you look at the product page and on Amazon, it seems like a lot of thought has gone into the chair itself and what it's capable of, but there is no mention at all about the castors, and this is an area where I think the chair trips up quite quickly. I found it difficult to move the chair in any direction. I asked a friend who came to visit me earlier this week to test my findings, and she said that the wheels were "no good," so it definitely isn't just me. I am 6'2 myself and a big guy, I work from home and gained a few pounds from mostly staying in and the hell away from other people. However, the Doro C300 Pro V2 is rated for up to 150kg (330lbs), which in my case is used well within its max rating. Ergonomics The number of adjustments you can make, right up to setting it in nap mode — which I haven't fully tested yet — is what you'd expect from a premium chair. Yes, you can go up and down (max 7.5 cm adjustment), rock back and forth (with tilt adjustment), and lock the chair between three stages of 105°, 120°, 135°, which is not quite as flat as the AndaSeat I tested at 160°. Some thought has also gone into the "8D" armrests, too, which are cushioned but quite firm; you'll only know it if you press hard into the PU-covered tops, which give about half a centimeter, but it's enough to ensure your skin won't get awkwardly stuck to it in warmer (or sweatier) conditions. It almost feels like plastic and is very easy to keep clean. However, the armrest positions move far too easily, and I am not sure what that "elbow" function is. Maybe it is good for a short person with short arms, anyway, I never used it and kept it flat at all times. There are eight levels of adjustment for the armrests, they are: backwards, forwards, swing left/right, height up and down, tilt, and 360° rotation, which can be handy for desk clearance. As I said, the armrest pads shift far too easily, which could give off an ergonomic vibe, but who wants the armrest sliding when you are shifting weight? The height adjustability does lock into place when lifting and adjusting. Comfort This is ultimately what it boils down to at the end of the day, right? Quite a lot of reviews praise the comfort of this chair, and I don't disagree that the mesh seating is quite comfortable. I am used to the material from my daily Herman Miller. However, the backrest cannot be locked into place, and this is actually a feature; as you shift or recline yourself on the chair, the backrest moves with your body. It took some getting used to. The lumbar gives ample support, but I would have preferred an adjustable one built into the seat base, as this causes the backrest to move up and down at will. Again, as with my previous chair review, this chair is also rated for tall people, but nowhere in the product documentation does it say how tall. Being 6'2 myself, I'm happy to say that the backrest is tall and wide enough, and thought has been given to being able to adjust the neck rest, but as others have mentioned in their reviews, people as tall as 6.2ft is about the limit for the neckrest. Conclusion What I didn't like The footrest is rated for 15kg (33 lbs), which to me seems a bit light, and after looking online, it seems like a chair footrest for adults must be at least twice that rating. In all honesty, they are just hollow metal tubes, so it is not recommended to let a kid sit on them. I also feel like it doesn't really go out far enough for my height, so that kind of puts the dampener on me being able to use it regularly. I'll just have to continue to use my subwoofer as a footrest! I do not like the armrests being able to shift around as easily as they can, and they are a little too forward-positioned in the chair to comfortably sit close to my desk, because even in the lowest height position, they don't allow me to go under the desk like is possible with my Herman Miller. I also feel like this chair could have been delivered partially constructed, especially the armrests on the seat, and why the aluminum base wasn't already pre-constructed (without the castors) is baffling, considering it would have fit in one of the two boxes that way. The instructions also need to be clearer. On the pamphlet, there's an A to X listing (which is also used in the steps), but none of the physical parts use this lettering system! What I did like I'll be honest, I haven't used it for very long, just one week, and seating comfort is subjective after all! Any spills wiped straight off it, the stitching, and the lines look great, not a fray to be seen or stitch out of place. It looks kind of cool, too. My favorite feature of these seats is the nap mode. While you're not lying completely flat, it leans far back enough to make you easily doze off after a heavy gaming or working session. Overall, this chair offers plenty of comfort features. The MSRP does vary quite a bit depending on the region, at £549.99 in the UK, and €580 in Europe, and $599 before tax in the U.S. However, shipping is free, which is a bonus for such a heavy item. Is it worth it, though? At three years' warranty, I think it's a decent deal. Another firm out of Germany sent me a free replacement hydraulic gas spring for a chair that failed after almost four years, so it was well outside its two-year warranty. My advice is to always try, as you might have the same luck I did. If I could fault it at all, it would be the constant shifting of the armrests and backrest. Where to buy Although the footrest variant normally costs $539.99, it has been discounted to $469.99 on the official website in Black or White. In fact, the non-footrest variant is only $40 cheaper. On Amazon, it currently costs more at $499.99 links below.
