Silly question pertaining to HDTV + Computer

Maybe I should already know this but can I spit an image from my computer onto an HDTV that can do 1080i @ 1600X1200????

Or am I stuck trying to get upto the max of the TV which I believe is something like 1920X1080?

Edit: I suppose 1600X1200 isnt possible. But can you get close?

thx
 
I havent tried it yet as I dont have a HDTV.

But the reasoning behind it was I was going to use it as a workstation and play games and switch to watch TV or DVDs.

Playing at that rez will be taxing on my GPU. I was curious if you can indeed spit different resolutions on the TV?

 
You should be able to use other HDTV resolutions like 1280x720 or 720x480.

I guess it would depend on the TV whether it supports other resolutions, but it should support all those HDTV resolutions.

Most TVs (even HDTVs) will not support other resolutions. With software like PowerStrip, though, you can 'embed' a lower-resolution image into a higher-resolution one, either keeping it 1:1 or doing the scaling in software. I believe NVIDIA and ATI offer this to some extent in their drivers as well.

Do you happen to know if the scaling degrades picture quality significantly?

I haven't personally tried it. It's probably similar to how a good LCD monitor looks if you run at lower-than-native resolution.

You could also try it on your regular monitor; just tell it to run, say, 1024x768 scaled up to 1600x1200 and see what comes out.

1080i means 1920x1080 @ 30hz, so you are never going to get 1600x1200 or any other resolution at "1080i." As for running 1600x1200; some HDTV screens will and some won't, so it depends on what you get.

As for scaleing, that again depends on what TV or software you are using.
 
there are plenty of progressive scan screens that will display 1080p singals, and a few LCD screens that actually are 1920x1080 native.
 
If you use YPbPR to connect with your HDTV display, you can do something similar to what you want using Catalyst drivers and an ATI card.

My RPTV only supports 480p and 1080i timings and I "map" a gaming resolution of 1280x1024 to my 1080i Display. Catalyst drivers "used" to have a feature called CTS or "Center Timing Support", now it is apparently enabled automatically.

What it does is map the 5:4 resolution (1280x1024) to the Center of my widescreen (16:9)display leaving black bars on the side. I picked that resolution because on my display the bars are only on the sides and menus are visable top and bottom, my rig can handle that resolution in most games, and it is supported in most games. You can play around with different resolutions to find what works best for your display, and it also has custom timing support as well to configure the display itself (example: 1776x1000 as "1080i" timings) so that you can minimize overscan.

To play "any" game on my widescreen, I simply make my Widescreen the "Primary" display and start up any game (its best to pre-configure game resolutions to 1280x1024) and Presto..Widescreen gaming with no custom resolutions, powerstrip, messing with timings.

I still prefer to play in front of my 22" CRT, but it has made all the difference for ease of use gaming on the big display..anyone who has configured their display with powerstrip for gaming in interlaced timings knows exactly what I'm talking about.

Not really "Widescreen gaming" when you are running with black bars though, eh?

Well, my example was for mapping a gaming resolution to a widescreen display like the OP was wondering about. Some games do support widescreen resolutions (few), and in that case it would be "widescreen gaming". I've found no easier way to game with decent IQ for virtually any game that supports 1280x1024 on my large display.

The point is, is that your games will run in proper aspect ratio on your display mapped to the center without alot of hassle configuring your display. If you've tried gaming on a 1080i display using VGA, RGB, DVI or YPbPr, you know what a hassle it can be.
 
I guess I'm lucky my ED screen takes just about any resolution I though at it and only needs a bit of position adjustment if its not at 60hz.
