Hello, I have recently gotten a Beelink SER8, and it’s been great. My one issue is that during general use (nothing specific as it can vary from playing games, media viewing, or just web browsing) the display will turn black for 2 seconds, then shortly resume as normal. Initially I believed this to be an issue with my monitor, however after extensive testing and fixes I am begining to reconsider if this is truly the culprit.

For reference, I don’t seem to have a way to nominally trigger the issue, so any suggestions or fixes y’all recommend may take at least a couple days of testing before I can confidently determine if it’s been resolved.

Below a list of the fixes I have tested up until now which did not work can be found.

Both my Desktop and Monitor are connected to the same power strip (which is rated more than sufficient for their power consumption). Their power cables were swapped around a few times to rule out a faulty plug, however I strongly believe this is not the cause, as neither device shuts down completely, indicating no power fluctuations.
My monitor supports 4k at 120fps (Dell S2725QC), so in-case the provided cable was insufficient for the data transfer, I have tried and tested others, all of which continue to eventually result in the issue, indicating the cable is not the fault and is in-fact HDMI 2.1. For all future testing, the cable was returned to the one provided along with the monitor.
As sugested by AMD, I did a full reinstall of the graphics drivers by first uninstalling any using their dedicated software, then later reinstalling them based on the resources Beelink offer for download from their website. https://dr.bee-link.cn/?dir=uploads%2FSER
I have reseated all relevant cables (power and display) within the Desktop and Monitor to ensure they’re connected securely.
The monitor has had its settings returned to factory default through use of its on screen display. This also involves disabling auto-select, in-case an additional input was causing the problem, although for clarity nothing else is actually connected.
Variable refresh rate was disabled, aswell as AMD Freesync Premium through use of the AMD software (since the monitor supports it)
The most recent drivers for the monitor were downloaded from the Dell webpage (much like how the Beelink AMD ones were).

I have probably missed a few other steps I’ve gone through, but I hope it’s clear I am trying a whole array of things to fix this. As such I would appreciate and support any advice others may have on the issue.

Thank you,
Ash
