I received my replacement PG279Q about 30 days ago and so far so good. Picture quality, blooming, glow are all good and I also don't have that annoying line down the left margin of the screen and the screen tearing in the center.

Now on to my latest issue: Whenever the monitor is placed in 165Hz mode (my first PG279Q wouldn't stay in this mode for more than 5 seconds) and my Win 10 machine sleeps, it wakes just fine. However, when I try and reboot the machine or turn it off and turn it on later, it freezes at the bios screen. Then after holding the power button down, waiting 10 seconds and trying again, the same thing happens. After a few tries, eventually I get to the blank screen with the Windows 10 logo in the middle. Then it freezes there. A few more tries and finally, I'm back at the desktop.

Its almost as if the computer needs a running start to get to the desktop (which in reality is impossible since the only way to proceed each time is to start it again from a cold stop. This issue does not occur when Over Clocking in the PG279Q is turned off.

Any ideas?

1. Unplug every single device on your computer except your 279 monitor. (yes remove your mouse and keyboard, also make sure you didn't have the monitor USB thing plugged in either only have the display port in. Not a single other cord other than power.). Hardboot your computer and see if the issue still exists. If this works and it doesn't freeze plug in only your mouse and keyboard and power off the computer completely. Reboot with your mouse and keyboard in like 5 times to verify that its all good. Plug in your external devices one by one to find what the troubled device is(maybe you just gotta reinstall drivers or it or something easy.)

2. if it still freezes plugin your keyboard/mouse and try resetting your BIOS settings to default(make sure you fix your boot order if it changes. Unplug keyboard and mouse and hardboot again. If this works its probably a simple BIOS setting that is causing a boot issue. flip some settings around by using your instincts and maybe you'll find the actual issue. if still freezing its safe to say that its not an issue with external devices or the BIOS settings most likely. You could try a BIOS upgrade but i wouldnt go with this step until everything else is not working.

3. If those 2 don't work it's most likely something in your current windows installation that is causing the issue. Have you done the manual installation of the drivers that come with the monitor? I know most monitors are fine with just PnP default driver but I noticed that once you install the correct drivers it will actually pick up as the correct monitor. If that doesn't work or you have already done this I would say try uninstalling all monitor drivers that you can find on your computer using device manager | View | show hidden devices | right click and uninstall everything in there even it if currently connected. reboot and see what happens (reinstall the ASUS monitor driver after the reboot, reboot again to verify).

That should give you something do to. let me know if any ofthis works. Before I returned my 4 attempted at getting a good version of this monitor it had been running windows 10 with no issues. this leads me to believe you got a local issue with your installation of windows.
