Hi all, hoping someone can help here. I have 3xBenQ XL2720Z 27" 144hz monitors, connected to Asus DirectCuII HD7870 in crossfire.
Cable connections are:
Dvi-D to Dvi-D, 2xmini dp to dp
Eyefinity works, crossfire works but i'm stuck at 60hz.
Now after a lot of reading online and some stuffing around I worked out if I only have 1x monitor connected by dvi and the others unplugged, I get 144hz on the dvi connection. I can add the second monitor mini dp to dp and have both running at 144hz.
I can then if I plug in live the 3rd monitor mini dp to dp get all three at 144hz recognized in windows and CC. But as soon as I restart my pc it reverts to 60.
If I try to connect the 3rd screen while off it and then start it up again I get only 60hz in Eyefinity.
Interesting if I disable eyefinity, I can set both the monitors on DP inputs to 144hz, but not the DVI-D connected monitor its stuck at 60hz unless only 2 screens are connected first and the 3rd plugging in live.
It can obviously do it all at 144hz, but to stuff around plugging and unplugging monitors each reboot is a bit much.
So I am wondering if adding an active adapter that supports 144hz would help? but I only have on the card:
1x dvi, hdmi (which I know doesnt support above 60hz so I didnt even bother with that) and 2 mini dp.
so with an active adapter how would I connect it? dvi-d to dvi-d, active mini dp to DVI and a mini dp to DP?
Can anyone confirm if that would work or if there is another way to keep the 144hz setting after a reboot?
