[Solved] PS3 HDMI Problem (Pixelated Image)

[EL1TE]

I'm having a problem, my PS3 HDMI was working fine until today. I have the LG W2361V monitor (using 1080p) which is being used for both PC and PS3 (PC using DVI port and PS3 using HDMI port). The monitor has a button that switches to from DVI to HDMI and so on.

It started have a Pixelated image in GT5. I've noticed this because i was doing B-Spec (AI drivers), and i was in DVI mode browsing the internet. If i leave the monitor on HDMI for a while it gets a better quality, maybe it's from the monitor switching modes causes Pixel corruption. However i already tried to turn off the PC and it didn't work at all. I've cleaned both HDMI ports and cable and still nothing. I've set PS3 settings to default and put them back and the problem is still there.

For example, the photos taken from GT5 look pixelated in some parts when i see them trough the PS3, while on DVI (PC) they look normal. Any ideas why this is happening? :/

EDIT (To post bellow): The problem is not from the PS3, it's from the monitor (rarely from the cable unless it's version 1.2 instead of 1.3b/c or 1.4 -- but for consoles 1.4 is useless since 1.4 it's for bigger resolutions that the current consoles can't render, you can always buy one 1.4 to keep it for the future and have it guarantee that it uses the maximum data transfer that is necessary for maximum image quality). Because it doesn't transfer all the data trough the HDMI cable since it's also focused on the PC (DVI), if you turn off the DVI or stop using it for a while, and let the monitor focus on HDMI, the image gets better considerably. If it doesn't help you, that's either your HDMI Cable is not an High Quality one or your Monitor/TV has no deep color or has color issues overall, in my case i have an LCD, however LED seems to be considerably better. Also remember that it depends on the games you play, some games have more jaggies than others, and most games are upscaled fom 720p to 1080p which can cause this, however LED and truecolor (and better color depth) displays seem to do the job well. There's also another thing that is using the AV cable instead of HDMI, most likely will solve the problem at the cost of image quality, however there's AV to HDMI convertors, but in my opinion they're kind of pointless since the AV cable and port can't send the same amount of data as the HDMI port and cable. Now, if you're thinking about buying a new monitor/TV for your console make sure you test the console on another TV or monitor first to see if that helps, if so then that's the only way, also i recommend people to buy a LED display instead of LCD, they do cost more but you can buy a smaller size one instead of buying an LCD and have the same issue again, and read reviews of the monitors before buying them. Good luck! :)

Just for reference here's what happens in some cases along with pixelation (noise), which again is a monitor issue.

8-Bit Color (16 Bit also has noise, reduce but noticeable - along with another color problems)

True Color

Almost all cheap LCD displays (such as typical twisted nematic types) use dithered 18-bit color (64 × 64 × 64 = 262,144 combinations) to achieve faster transition times, but they must use either dithering or Frame Rate Control to fake 24-bit-per-pixel truecolor, or throw away 6 bits of color information away entirely.

Ok, seems like i've fixed the problem or at least it seems much better now. Probably i just didn't notice before because i wasn't looking closer enough to the monitor.

What i did was going to Settings > Display Settings and change the value of RGB Full range to Limitied (which is set to this value by default but for some reason i always turn this to Full, when i've restored to defaults it asked to configure video settings again and probably i've set this to Full (again), this settings improves image quality, it makes the colors richer and overall image quality also looks sharper)

I've also set the monitor to Overscan ON, which can be found under Setup > Setup (Last on the list at the bottom, in the same place where you can choose language), however while on DVI and using the PC it doesn't show this option which makes me think the problem might be either on monitor's HDMI or this is actually how it should be.

I've also tried to use the HDMI cable trough the Graphics Card and again it looked OK when using the PC, however i've used a DVI to HDMI convertor since the card doesn't have a HDMI port, so the problem is not the cable. Anyway i'm happy now and i can say it's fixed, hope this helps someone in the future. :)
