completely at my wits end with this one! Previously had a three monitor set up, all running at 1920x1080 and bought a Asus VX24AH as a fourth.
Unfortunately i cant for the life of me get my Radeon to output at the monitors max resolution. The problem isnt helped by the fact that the Asus doesnt have miniDP or DVI inputs. I've also tried some adapters i have lying around to get the resolution up:
- miniDP to HDMI
- DVI to VGA
- DVI to HDMI
I would hazard a guess that i need some kind of active adapter but i'm computer unsure as to which i'd need or whether i'd be guaranteed success?
The HD6850 can only support up to 2x passive display connections, HDMI/DVI etc. You'll need to use a native Displayport and an active adapter for the third monitor and beyond.
What make and model 6850 are you using?
