Hi All,
I wonder if anyone else has had the same issues are we are currently experiencing with a GTX 1080 FE plugged into 165hz 1440p GSYNC monitors such as the ASUS Swift PG279Q or the ACER Predator XB271HU (we have currently got one of each).
I initially plugged in the ACER for a new build PC [z170 hero MB + GTX 1080 FE + Samsung 950 pro ] via display port. I could reach the UEFI bios and saw POST images on boot each time. I then installed windows 7 (on the 950 this is rather tricky!) and started the update cycles - the monitor was running off the default drivers fine.
Here is where things started to go wrong. While windows was running, I unplugged the display port leading into the ACER monitor to check the ASUS monitor - no display port signal received on the PG279Q. Oh Bugger, I thought and quickly swapped back to the XB271HU. No signal! I had a route around for some other cables (using display port cabled supplied with the monitors) and found HDMI-HDMI and DVI-HDMI cables - plugged them into both monitors with no signal (I did switch inputs for both monitors!).
Had to perform a hard reboot at that point (windows 7 update was in the 'stuck' phase at this time). On the next boot, we saw no signal through display ports for either monitor. Eventually, after many combinations the DVI-HDMI was the only thing posting a signal. We installed nvidia drivers, and eventually got the 2 display port inputs working in windows (this required a 'reset' of the monitors). I also 'overclocked' them both to 165hz successfully in windows. All was good.
On the next reboot I noticed that neither monitor was displaying and POST or UEFI bios signals, but did spring to life when windows loaded up. I can only see the UEFI bios under DVI-HDMI now, which is now viewed with a different aspect ratio (the UEFI uses a fixed resolution doesn't it?). I have bios CSM set to 'legacy only'.
So I am confused, we get a display port signal only in windows on both monitors. Has anyone else seen this problem? If so did you managed to fix it? Most of my searching led to the answer 'use the HDMI interface' which obviously makes owning such a monitor pointless since GSYNC only works over display port.
