Can sending the wrong resolution hurt your TV?
I recently got a new video card (ATI X1950 Pro) and have been playing around with various resolutions trying to get the best possible picture.
My display is a Prima 32" LCD TV connected by VGA (connected to the DVI port on the video card through a DVI-VGA adaptor). The TV has a native resolution of 1366x768 and I normally run Windows at 1360x768. However, for games I often prefer a higher resolution so I can get more information on the screen -- for example, I run Everquest 2 at 1360x960.
The ATI Catalyst Control Centre says that my TV reports that its maximum resolution is 1440x960. I can force HDTV resolutions (1280x720 60Hz and 1920x1080 30Hz) -- the first is pretty much the same as my default and the second doesn't look very nice due to the 30 Hz refresh.
As an experiment I tried forcing it to use 1920x1080 60Hz and my TV recognized it and displayed it. Given that this is essentially "1080p", which as far as I know my TV shouldn't do, is it safe to use this resolution, or even higher ones? Am I correct in thinking that whatever you send to the TV is intercepted by the TV's scaler which should simply reject whatever it can't recognize?
Is the theory "If it displays it's ok" a good one?
Also: Currently, the HDMI port on the TV is connected to my DVD player and the Component ports are connected to my cable box so they are unavailable for use by my computer. Would I get better results by using one or other of these, or is VGA just as "good" as component/DVI/HDMI?
