Hello,
I recently purchased the PG278Q and I cant seem to get it to display above 100hz without it going black with an "Out of Range" message.
System specs:
Rampage V Extreme X99 (bios 1001)
i7 5930K
32GB G.Skill 2666
x2 Strix GTX980's in SLi (Driver ver 344.48)
Windows 8.1 64bit
x4 250gb Samsung 850 evo SSD's in RAID 0
4tb WD Green
In the Nvidia control panel under Display>Change resolution it only shows 24,60 & 85hz under "native"
Under Custom, it shows 100 & 144hz.
When I choose 100 it displays fine, but once I hit 144hz the monitor gives me the "Out of Range" message. I wait and it reverts back to 100hz.
If I press the "Turbo" button on the monitor, it will cycle up to 100hz, press it one more time and it goes "Out-of Range" and then the turbo button has no affect. I must either disconnect the power to the monitor or disconnect the displayport cable and then reconnect it. The monitor is back at 100hz at this point.
UMLB is off so I know that is not limiting it.
I called Tech support to see if they could help but they told me to come here as they believe my "Video card needs tweaking to achieve 144hz, but we don't support that"
I'm at a loss for now and could use some direction.
Is there anything else I can check or do I need to RMA this thing?
Thanks in advance!
