lxsapper Posted August 23, 2013 Posted August 23, 2013 I bought a used LG LED 32" FULLHD TV today to use as my main PC (Flight sims!!!!!) display. I also have a 21" 1600x900 touchscreen wich I used to have with my now to retire 19" 1280x1024. I used to run both windows desktop and flight sims such as DCS without any issues with each screen using it's native resolution. But now I can't use the TV and the touchscreen toguether. They both connect just fine buth I can only have the Desktop in one or the other I can't expand the desktop or duplicate it. My GPU is a Saphire HD6870 with 1gb graphic memory. The card has 2 DVI connections 1 HDMI and a couple of dysplay ports. It used to ge connected to 1280x1024 with a standart VGA cable using the DVI adapter provided. The 1600x900 touchscreen was and is connecter with a DVI cable. The FullHD TV in now connected with a HDMI cable. Anyone has some idea on how to fix this?
lxsapper Posted August 23, 2013 Author Posted August 23, 2013 Ok I partially solved the problem, but now I have another issue. Aparently my Graphic card cannot display a DVI and a HDMI output at the same time. At least I solved it by connecting the TV with a DVI to HDMI cable using both DVI outputs on my graphics card. The problem now is that I now have some horizontal jagginess on the TV, it's not terrible but it's not good eighter, and I don't have this issue using the HDMI cable. I don't know if this is a problem because I'm using the DVI to HDMI cable, or it's a problem with the cable it self since it's a cheap one. Anyone have experience using such a cable with a FullHD display?
lxsapper Posted August 23, 2013 Author Posted August 23, 2013 Ok found the solution, setting the TV to "Just Scan" and not "16:9" or "Original" (what I had) solved the Issue.
BHawthorne Posted August 23, 2013 Posted August 23, 2013 I also suggest going into the tv menu and turning off any video processing options. They will induce latency.
