PC games Choppy on HDTV

[drgnswy]

I live in the USA. I have a 60 inch sharp aquos lcd and a 55 inch lg led 3d tv. BOTH TVs ARE ON GAME MODE. I do not have a lag issue. All games are choppy/FRAMIE when played on these tvs. i am running a good computer. quad core 6gigs ram good nvidia card with dual dvi outputs. everythig is smooth on the tvs except when i play games on the pc. I am using a dvi to vga adapter to plug it in from the pc to the tvs. Running windows XP. I am playing an old game. Unreal tournament 2004. When I play on a pc monitor the game is smooth and fluid. Any one know whats wrong???

Use HDMI.... and what video card is it.

[Bond007]

What is the processor (CPU), and what is the graphics card?

seems that gpu hasn't enough horsepower try a lower game rez eg, 1024-768

that is my thought also possibly because of the 60" screen being so large

Size shouldn't matter; it's resolution that will make the diff, and Unreal 2004 @ 1080p with a decent GPU shouldn't be choppy, IMO. I'd be looking at swapping out that VGA adapter with a DVI->HDMI adapter. Might have to do with how your TV is processing VGA.

Just my guess, of course.

Size of the screen doesn't matter at all. Only resolution matters.

I7965 quad core 3.2.... Evga 260......the computer is more then strong enough to run the game. It's just that when I play on my old CRT monitor its so smooth and fluid like I can hit anything I want but on these tvs it's choppy. I have the refresh rate at 60 hz. Then I try 75 and then I even try 120. But the weird thing is when I tell the graphics card to force a refresh rate of 120 and the pc says its running at 120 the tv display says its still 60. Idk. All I know is that it's choppy on the $1500 tv and the old monitor its perfect and I don't know how to fix it. Maybe I should try a dvi to hdmi adapter with a high quality cable and see what happens

It's probably the VGA... VGA doesn't handle 1920x1080 very well, try to use HDMI or DVI

Your answer was fully stated above :P

You just solidified them when you said it runs fine on ur CRT of course it does its a lower resolution. lower the resolution on the Computer when plugged into the TV not the refresh rate and all should be fine
