TV playback issues

[GLE3]

I am just starting to get into video capture and have a question. I had a couple AVI files(downloaded off the web) I was watching on my TV this weekend using my laptop(Thinkpad A22m). My question: How come the video looks good on my laptop monitor but on the TV the background is pixilated. Is it just the quality of the file?(resolution of file 740 X 480). Is it the video card??? I am using WMP 11 to play my avi. Any info would be appreciated. Thanks!

Its the quality of the avi,if you are watching the avi on a hdtv you will see all the artifacts that arent seen as easy on a smaller screen.Get a good quality 1280x720 mkv and play it through your tv and you will see the difference.

Also, televisions have very different gamma curves than computer monitors. This makes details (macroblock artifacts, posterization) in dark areas much more visible on TV. And the bigger the display the more noticeable problems will be. I suspect your TV has a much larger display than your laptop.

Thank you for your responses!

Yep, my laptop is 17". TV is 35. It sounds like I might have this issue no matter what I do then? Does raising the resolution of capture help out with this? I hear some capture software comes with a deblocking filter. Would that help?

If you're doing your own caps you should be able to keep the quality high enough that you wont have artifacting problems. Most stuff you download from the web is way over-compressed.

You should also calibrate the computer's output so that the levels and colors are set correctly. You'll find the video overlay proc amp controls in the display driver's setup applet.
