[Request] SDTV Vs. HDTV Comparison Pictures


Recommended Posts

Anyone have any pictures of them both? Because I want to see whats really the difference, cuz I just bought a 32'' HDTV today and last time I tried it on my 30'' HDTV ( which belongs to my parents ) I didn't see much difference at all.

( Well atleast the words are biger now =P )

that actually would be cool to see... especially if someone could somehow get a pic of the same scene... i've heard watching sports in HD is the best, and for normal movies and stuff it's good, but not all that much better...

i only have one movie in HD which is sin city. i just did a shot of jessica alba, half of her in HD, half in SD... you can see which is which.

i'm pretty sure i got the same frames... so it should be a good comparison. remember that she is moving in this shot, so some motion blur is expected.

Your probably not going to see much difference because both TV's were running the same resolution. Which on a 32" HDTV is most likely 1366?768 at maximum, but if you were running the 360 through the component cables then it would be 720p - 1280x720...

If you had a TV around 40" plus in size you would see a definate difference between things like 1080i, 720p and SD resolutions.

Here is a screen capture I took of HDTV (1080i) versus SDTV (480p) on my computer:

If you can't tell the difference your blind.

I basically took half the of the HDTV image and stuck it next to a full size SDTV image so you can compare resolutions.

Note: SDTV is off cable and HDTV is over the air. The TV tuner card i'm using is pcHDTV for Linux. I took the screenshots directly from Mplayer.

so are the diagonal lines a feature of HDTV?? Another thing that ticks me is why you have to be over 40 inches to have a benefit of this 1080 stuff. While a 19inch crt computer monitor does it no problem.

You mean your parent's SDTV?

Are you using the component cables (Red, Green, and Blue) correctly and with the switch set to HDTV? Also did you change your display settings to 720p in the dashboard? The text is about the same relative size going from my old 32" SDTV to a 40" HDTV - it's just much clearer.

Those diagonal lines you see are analog distortion. Cable card isn't available for Linux, so I can't get the digital signal directly.

The nice thing about doing HDTV on your computer is that you can set up an HDTV PVR. That's actually how I have it. I've written scripts for Linux to record HDTV content onto disk so I can play it back whenever. Although be warned that 1 hour of raw HDTV footage is about 16GB! You'll want to transcode to xvid or something similar.

I was just asking because it's easy to forget the things you take for granted. I know it took me a minute to realize my 360 was set to 480p by default when I first hooked it up to my new HDTV.

It's because with a monitor you only sit a couple of feet away, but with a TV people typically sit 8 or more feet away which makes it harder to see the tiny details. So with smaller TVs you'll have to be sitting much closer to see a big enough difference for it to matter.

I recently bought a HDTV, 1080i. Compared to my old SDTV, it's pretty damn nice to watch HD. It's amazing how the extra clarity really provides a more enjoyable experience with the same content.

Cool nice picture, but I think I'm going to let this thread die off since my parents won't give me the HDTV, now they have two .....

Now I'm stuck with a 1999 TV -.-

You should show your parents the gaming setup thread and tell them that these are all kids from your school. :shiftyninja:

480p and 720p isn't a noticable comparison when watching the movie, unless you have a very fine eye for detail.

but going from SDTV to HDTV (1080i/1080p) is like watching a video on your cell phone, and watching a video on youtube. you don't get the full effect when watching it on your phone..

Phone videos and youtube videos are both horrible. :|

I find the difference between 480p and 720p to be very noticeable--are you watching movies on an HDTV?
