Hello there, I just bought a 22"TV, and when I connect it as my monitor with a HDMI cable the picture looks all strecthed. I tried to set the resolution on all possible ways but it automatic gets to 1600x900 or some other resolution. When I connect my 17" COMPAQ monitor it has the resolution 1650x1080 but on my tv there are only 1600x900 and 1900x1080. My graphics card is an nVidia 9800gt and I'm running XP.
You are only going to be able to run your system at resolutions supported by the display and the PC/laptop. Remember, LCDs/LEDs have what is called a "native resolution". Sounds like yours is 1920x1080 (1080p/1080i). Operating at any other resolution will require "stretching" (scaling) the image or black bars around the image.
I tried to set my resolution with both, nvidia control panel and with windows
also i tried making my own resolution but nothing happens t just changes the resolution on 1600x900 or 1900x1080, and yes it is a TV, but I haven't tried any other connection just trough hdmi.
