Hi folks,
I have a brand new (bought mid July) ROG Strix G814JVR.317, Win 11 home 64-bit. Corei9-14900HX, 32 of RAM, with an NVIDIA GeForce RTX4060. The graphics card has an HDMI 2.1 port as well as 1x USB 3.2 Gen 2 Type-C support DisplayPort™ / power delivery / G-SYNC and finally, 1x Thunderbolt™ 4 support DisplayPort™
To pair with this, I have a 31.5" Acer ZX322QU QHD monitor, also brand new.
When I connect the monitor using the HDMI cable, everything appears to work fine. The HDMI limits the refresh rate to 144 Hz which is "probably fine", but not quite what I paid for, so, I ordered a DP-to-USBC cable so that I could use the DisplayPort, and get 180 Hz, to see what that was all about.
However, when I connect it using the DisplayPort-to-USB-C cable, the monitor drops right off the Device Manager whenever the PC goes to sleep or I reboot. It remains powered on (blue LED indicator), but doesn't wake back up on its own; I have to manually hit the toggle button behind the monitor, at which point, Windows then recognizes it and re-adds it as a Monitor in Device Manager, and it shuffles the displays back to normal.
Hitting the toggle manually 15 times a day is a chore that I didn't sign up for, and not something I'm eager to embrace in my brand new hardware. I'm within my return windows here, so am trying to see if I can solve the problem before then. Any help would be most welcome.
Here's what I've tried:
- I have tried plugging it into both of the USB-C slots to see if that makes any difference; it doesn't.
- I have updated the monitor driver to the latest one from Acer (though it's not that new; from 2020.) Prior to this, it was using the "Generic Monitor" from the monitor.inf that ships with Windows.
- I have tried uninstalling the monitor, factory resetting it internally using the OSD, unplugging it, and holding its power for 1 minute, then reconnecting it. (an Acer Support suggestion.)
- I have updated the NVIDIA driver to the latest (currently 560.70)
- I have tried jolting it to recognize it after waking using Win-Ctrl-Shift-B.
- I have tried disabling G-SYNC (on the PC) and Freesync (on the monitor)
- I have tried disabling on the monitor: Quick Start Mode, and Auto Source
- Importantly, I have connected this same monitor using the same cable to my wife's laptop - no drivers, no modifications, no setup needed. It wakes from sleep JUST FINE using DisplayPort in the USB-C.
- I repeated this test with my son's laptop. Same deal - it wakes from sleep just fine using my existing cable with zero setup, and Windows doesn't drop the monitor as a device when it sleeps.
So, why does this laptop drop the monitor as a device whenever it goes to sleep or reboots? I haven't been able to figure this out yet. Any suggestions would be most appreciated, as this is starting to feel like a defect in the laptop.
