Which one exactly did you set it at?
I have 2560x1440 / 144 Hz monitor (LG 27GL850) and Sapphire Pulse RX 5700 XT
(hardware switch set to higher performance BIOS) and in general I noticed a
similar thing. During normal idle KDE operation, power stays at around 32 W or
so.
If I suspend and resume, power drops to 11 W and the monitor starts flickering
wildly. I tried to do:
echo "low" > /sys/class/drm/card0/device/power_dpm_force_performance_level
But that didn't really help with flickering.
Can anyone from AMD please comment, whether 32 W is expected power consumption
for light desktop usage at 2560x1440 / 144 Hz for Sapphire Pulse RX 5700 XT?
And clearly, after resume things are now broken regardless of what's the normal
level is supposed to be.</pre>
