My monitor does the same thing. I am using a NVIDIA GeForce GTX 1050 Ti.

Hi,
I have fedora34 installed on my desktop with three monitors; two of
them are older 27" Samsungs, and the third is a new 34" Samsung
S34J55x. Occasionally, the 34" seems to shut off for a second, then
comes back on and continues to work normally.
Has anyone seen this type of behavior before? The other two monitors
have never done this. However, when it happens, the other two seem to
follow with shutting off for a second. It always seems to be driven by
the new 34" monitor.
The problem is that, when this happens, all of the windows on the 34"
monitor move to the 27" monitor on the right once the monitors turn on
again.
This is not a power problem, as the entire computer is connected to
the same power strip, backed by a 2200W UPS.
My video card is also new - it's a Radeon RX570. All three monitors
are connected via displayport.
I do see lines in my Xorg.0.log file periodically along the lines off
the following:
[992023.990] (EE) event3 - Logitech Gaming Mouse G900: client bug:
event processing lagging behind by 16ms, your system is too slow
[994674.766] (EE) event6 - Logitech Gaming Keyboard G910: client bug:
event processing lagging behind by 29ms, your system is too slow
But are they related? Is this also an issue? The system itself is a
12-core with 64GB of RAM, so certainly not slow.
Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz
Please let me know what more I can do to troubleshoot this before
contacting Samsung directly.
