I have an older Vostro 470 (I7, 8GB memory) with Radeon HD 7700 Series, lastest drivers. I have two Dell U2713HM Monitors. Using HDMI High Speed cable. The desktop has DisplayPort, HDMI and DVI as outputs.
(With DisplayPort I'm able to run 2560x1440)
(With DVI I'm able to run 2560x1440 but the image is distorted with green/red lines.)
With HDMI I'm only able to run 1920x1200
Wanted to run two monitors maybe.
Anybody knows what is the upper limit on HDMI resolution on this desktop/graphic card? Can't it go higher than 1920x1200?
DVI and DisplayPort are for computers. HDMI is for consumer electronics (like projectors and HDTV). Back then, TVs maxed out around 1080p .
