LG 31MU97Z-B - monitor sometimes sleeping after system wake

Recommended Posts

Hello!


Sometimes my monitor LG LG 31MU97Z-B won't wake after sleep. If i push power button on monitor for 1sec it's wakes. On Whatevergreen kext FAQ I found possible resolution for this issue - https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.Radeon.en.md.

Why can a highres DisplayPort-connected display fail to wake (e.g. some LG 4K models)?

Sometimes AGDC configuration preference could be the case. For 4K and lower it makes sense to try disabling it by passing CFG,CFG_USE_AGDC ā€” False (00) via SSDT or similar.


Is there someone facing already with that problem and can help with it?


My hardware is:


CPU: Intel 8700K

GPU: integrated

MB: MSI z370m Gaming Pro AC

RAM: 16GB

Monitor: LG 31MU97Z-B


My clover folder also attached.


thanks!

Now monitor permanently sleeping after system wake. And only pushing power button on monitor helps it to wake up.

System is wakes, but monitor sleeping and only pushing power button (menu button) on monitor helps it to show image (login screen). Something in system not sending right wake signal to the monitor...

One more interesting thing - when system wakes up by pushing power button on PC (case), monitor wakes normally.

use only power button, i kill other devices for wake, have only two, XHC and Power Button

u can remove in specifc method, device, scope, i like remove all and put one in xhc for wake in keyboard/mouse

In my case waking up with keyboard and mouse not always brings display to wake up. And I need to push monitors power button to wake it up. But earlier it was ok. But when I'm pushing power button on case, monitor wakes normally. Strange thing...

use only power button and remove _prw from xhc device


some LG 4k have it

But I think it's not monitor problem. If I push button on mouse my PC wakes in two stages (please see screenshot) - DarkWare from Normal Sleep and after DarkWake to FullWake from normal sleep. If I pushing power button on case we have wake in one stage - Wake from Normal Sleep.


Is there possible to program wake with mouse and keyboard same as with power button?
