1st check for heat. does the monitor heat up after 10-30 minutes?
2nd check for heat. does the ac adapter (if there is) heats up after 10-30 minutes?
3rd check for heat, are you running on gpu or onboard gpu? (for gpu check if your gpu is running or not) fan stopped?
4th check, is it just your monitor shuts off or the entire pc shuts off?
do let us know what is the outcome.
Thanks for replying,
I did this things and this problem keep happening,
-I did run Dell's self diagnose system, no problem found.
-I changed to another monitor ac adapter, still happen. I also changed the new extension socket cable just in case it could be malfunctioned. No luck too
-PC is working fine, fan is spinning and such. Only monitor no display like it dont receive power from ac adapter.
-I use onboard gpu. Older one thats it.
-Monitor set to lowest brightness and power saving so I dont think it overheat.
