Oh No, My PC Monitor Goes Blank When Fullscreen On Endeavor OS Linux KDE Plasma!

When I first ran Endeavor OS on a new PC device. I tried to watch a video, and when in fullscreen mode, suddenly the monitor screen went blank like the monitor was dead. At that time I clicked 2x using the mouse so that the screen became fullscreen. In addition, trying to use the F11 button on the keyboard is also the same. The point is when entering fullscreen mode, the monitor screen immediately goes black but does not turn off because the indicator light is on.

In this case, I use a 24" Asus monitor, for a PC device using AMD Ryzen 5 5600G, and the Linux Endeavor OS with its KDE Plasma Desktop Environment display, and does not use a discrete VGA or still uses the Ryzen default igpu.

Solution:

After finding out the problem in the forums, I saw a post with the same problem, about the monitor going blank when fullscreen. So in this case I only need to change the settings from the Display Configuration. To change it.

Solution For Monitor Blank When Fullscreen on Linux

Please open Display Configuration and look for the Adaptive Sync menu, there if it is still in the Always or Automatic option, please change it to Never, and Apply. After that, please try again to play the video and run it in fullscreen. The monitor should no longer go blank.
