Sorry to correct you, but my monitor has not been faultier than any other
MG279Q that was bought before 2017. I already had TWO other MG279Qs before =
this
one, both had the problem I described. The ROG forum thread I have linked s=
hows
the SAME artifacts I have described and these have definitely been fixed on
multiple platforms by the mentioned firmware update.
BTW I have tried the mclock increase before RMAing my monitor and it did not
work at all.
Please differentiate between the artifacts I described (left half of the sc=
reen
is offset to the right, a vertical stripe that should be in the middle is
displayed at the left side of the screen) and other artifacts which could in
fact be caused by a low mclock or other problems.
The described artifacts might be fixable by software (e.g. Windows with cer=
tain
driver combinations does show these artifacts, but does not with others), b=
ut
ARE CAUSED by the faulty MG279Q firmware.
I have not found any combination of OS and drivers that caused these proble=
ms
on the fixed monitor, but found several on multiple "not fixed" M=
G279Qs in the
past.
