560 TI 448 Core HDMI Handshake Issue? Tags: Graphics Cards Display Graphics Last response: January 8, 2012 8:03 AM in Graphics & Displays Share xxsjxx1 January 7, 2012 3:19:46 PM Ive been having a few weird issues with my HDTV I play my game on 1080P, but sometimes when i switch back to 720P to browse i get a weird messed up resolution until i shut my display off and turn it back on. When my computer turns off the display in 720P and i resume, its fine.... When that happens in 1080P and I resume, it says unsupported signal, and I have to unplug the wire and plug it back in to get a picture. Turning off the display doesnt restore it. My questions are, does anyone know of a setting or anything that will fix this? Also, is any of this hurting my graphics card? thanks.
