Lag For Video Proccesing On Hdtv?
« on: October 27, 2005, 09:53:00 PM »
More than a few people have talked about it, but knowbody has given any conclusive answers. If your monitor (HDTV of any kind) doesn't support a native resolution of 720p and you are playing an game. Is there gonna be lag because your TV has to upscale the picture to 1080i? If so what can be done about it? Can you turn off the picture upscaling?

I want to buy an HDTV. I wanted a 34" Toshiba 16:9 CRT HDTV. However I've seen that many CRT HDTV's don't support 720p nativley so they must upscale to 1080i. (unless someone knows of a good CRT that does 720p nativley?)

I've heard in some forums that people have experienced very small lag from it. It's not so bad for some games but if you play fast paced games or multiplayer the picture shows up just a hair slower than normal. This would cause's you to react another hair slower, causing video lag? Knowbody likes lag even if it would be predictable. I don't know if it's true or not. However the arguement seems to hold some water?

I don't have an HDTV yet. I use a PC montior and an X2VGA adaptor. I was just wondering if making the switch to an actual TV will come with the sacrifice of a laggy picture?

QUOTE
What resolutions will game developers be required to support?
Game developers are only required to support 720p.

Does this mean I need an HDTV that supports 720p to play all of the Xbox360 games?
No. Despite the fact that developers are only required to support 720p the video encoder chip built into the Xbox360 has the ability to up-scale and down-scale games to any of the resolutions supported by the Xbox360. This means that even if a game was only developed in 720p you will have the ability to play it in 480i, 480p, or 1080i as well as 720p.


Scaling lagg can come from any type of TV not just crts. The only way to ensure you don't encounter it is to try before you buy. Haul your Xbox to Best buy plug it in and try it.

If your display is native 1080i and doesn't require scaling for that resolution then you'll probably be fine, but often times sets aren't actually native to any HD resolution so they need to scale no matter what you feed it.

Pick a game where audio/video syncing is important , something like DDR would work well to test.
