Windows 8.1 display entension bug?

[ElementOfDaze]

So i encountered a rather weird bug today with my new monitor. I got a new 144hz BenQ xl2411z to be my main display, setting aside my old one as secondary. I wanted to show the difference between 144 and 60hz, so i duplicated the display, the res was messed because they were different (1920x1080 and 1680x1050). I ran cs:go and showed, then i left for a bit and reset it to extend current display. When i came back both screens were black (as if getting signal but no display). I restarted and tried again but it failed and the black screens showed up again. I really want to use both displays but i can only use one at a time, i am using the BenQ right now. Incase it may be driver related i have AMD RADEON R9 290 GA Windforce x3 with a small factory overclock. The driver is the latest Catalyst Driver (14.12).

I don't know how to help you here because you seem pretty stuck.

 

So you can't run both screens simultaneously at all?

connect each monitor seperately and set the resolution on both to 1680x1050@60hz even on the benq monitor

then connect both and I would expect that you will then have both displays running at that resolution.

at this point set the benq to 1920*1080@144p extended. 

just a guess but i suppose worth a shot

Not at all.

Wish I'd thought of that.

No luck. I tried to do what you said but it pulled the same thing :\ Not a huge deal as the monitor I paid 279$ is working fine!
