This is what they stated regarding 2 x DisplayPorts: Tomshardware have a review on this monitor. And I've waited for too long, for that repair. Though, I've sent it back, when I bought it, as it had a dead pixels spot. I can send it back, as it's warranty will end in a couple of weeks.
144HZ MONITOR AER DRIVERS
I've waited for windows/new drivers to maybe solve this hiccup. The thing is that even if I set Windows to //duplicate these displays// the same problem appears. Being set to //show only on 1 display// and having 2xDisplayPort enabled, may cause a miscommunication.

I think it has something to do with the signal transmitted from the GPU, after waking up. RTX 3080 Suprim X LHR 10GB ( on 3 dedicated power cables ) 5900X ( on the MB 8pin + 4pin power cables ) + AIO Arctic Liquid Freezer II 360 mm (top mounted – exhaust) 4 * 16 GB DDR4 3200 Mhz - G.Skill Trident Z Royal Lian Li O11 Dynamic + 6 * 120 mm InWin ASP120 intake fans (2 daisy chains (3 / daisy chain)) I’ve been fiddling a lot with this, so, hope for some new advices.

I just want to use this monitor at 144Hz, all the time, without switching from 120Hz to 144Hz all the time. The PC wakes up and is running, but I guess it’s bricked, or something, as I can’t restart it from the keyboard. The monitor goes into a no source state, and it keeps on searching for inputs, and then it hibernates. I just can’t wake it up, unless I restart the PC from the MB (the case doesn't have a reset button). When I turn 144Hz mode on (from the monitor’s menu), all is normal, until the PC goes to sleep. In Windows, I’ve set Multiple displays to ///Show only on 1///. ***Please note that this display uses 2 x DisplayPort 1.4 (the 2nd one is for 144Hz mode). The monitor goes to sleep and wakes up normally. I have an Acer Nitro 27" XV273KPbmiipprzx 4K 144Hz gaming monitor.Īt default, it runs at 120Hz, on one DisplayPort 1.4.

And it's been two years since I have this monitor. This is weird, but I didn't manage to find any answer, not even on the Acer forum.
