This is most likely caused by this issue: HDMI screen turns off when sustained high CPU usage on all cores · Issue #1598 · raspberrypi/firmware · GitHub - video output stops working when RPi4 overheats.
Make sure your RPi4 is properly cooled (eg heatsink or fan, if you use a case try without it) and/or avoid high workloads until that's fixed.

Makes sense, however, how come I don't experience these issues on your build posted in this thread?
What kind of issues did you have?

Nightly build of 28-07.
After starting downloads (transmission in docker), video output stops. Samsung tv indicates that resolution is not supported.
Libreelec and docker still seems up & running.
Setup:
RPi4, original power supply, wired internet, external ssd (Samsung SSD T5 500GB), single HDMI cable connected, boot via external USB thumb drive.
Logs:
No, it will be in the next release. Please test with nightlies for now.

Nightly builds (24th and 25th) directly gave issues; reverted back to your build and no issues for now.
I'm not proficient in retrieving log files.
If you could point me to a guide I can share them and provide feedback on the nightly builds.
Is this change also included in the RC1?
Parf can you please test this build? LibreELEC-RPi4.arm-10.0-devel-20210713215127-5ac3ead.img.gz - just copy it to the "Update" samba share (or to /storage/.update/ folder) and reboot.
It contains a 64bit kernel instead of the standard 32bit LPAE one which should hopefully fix the OOM issues (I suspect 32bit LPAE and HIGHMEM are causing the OOM issues as lowmem is rather small on these kernels).

Usually, I could pretty quick trigger the OOM issue by starting multiple downloads (Transmission, Docker) and playing a high bit rate movie at the same time. After installing this build, no issues whatsoever op till now.
Will report if I run into issues, but will be perfect if this change is merged to the next release.
