Televisions are bad to use as monitors. They have very low pixel densities, especially when you get into the larger sizes like yours. A 1080x1920 monitor usually comes in at 23 inches in diagonal size, but your television stretches that out to take up over four times the square footage of screen space.
The best option I can think of is to look for Windows accessibility features, or some sort of magnifying software. I'm running Vista and I have a magnifier in Start, Programs, Accessories, Ease of Accesss.
Magnifier idea is awesome, thanks.
TV actually looks 100% great playing COH ultramode, so I'm keeping it 
Anyone know how I can make MIDS render at a bigger size on my screen?
I push my PC to my native 1080p SONY 54" TV -- and at that resoluton, sitting 10 feet from the screen, MIDS is basically impossible to read. I've tried 2-column, 3-column etc. layouts but none of that really changes the size of all the graphics. I need the graphics to render a lot bigger.
Thoughts?
