Issue with reduced screen brightness after unlocking the display.
Issue with reduced screen brightness after unlocking the display.
I have an
Asus ZenBook 13 OLED (UM325SA)
with
AMD Ryzen 7 5800U
and
Windows 10
. After locking the screen and turning off the display, the screen appears visibly dimmer when unlocked, even though it shows as "maximum brightness". If I decrease the brightness by one step, the screen immediately becomes brighter. This is a
brand-new system set up just yesterday
. Whether it’s plugged in or not makes no difference.
What I’ve tried:
Searched through power modes (
only "Balanced" is available
) and settings for adaptive brightness, but the option does not exist.
Disabled
Fast Boot
.
Checked
AMD Adrenalin
for
Vari-Bright
or
Panel Self Refresh
, but these options are not available.
HDR is off
.
Issues with
MyAsus
can be ruled out, as I haven't installed it at all.
Firmware, drivers, and software
are all up to date.
UEFI
is very limited; I have no options that could affect this issue.
I'm at a loss. Does anyone have any ideas?

Re-enable it.
