Turn off the diplay setting in power keeps changing

I tried to set to 2hours/never but it always set it self back to 15mins after reboot and sometimes during use.

Make sure to switch power mode until you have set the options for all available modes.

i have my power mode on performance i think

dont work

Are you running as an admin? Maybe a program interfering? Try a clean startup - Troubleshoot Application Conflicts by Performing a Clean Startup

Im the only person using this coputer, I custom build it myself. My start up contains nothing besides my antivirus program. What kind of program would you think would interfere with this? by the way after hide all microsoft service program i see there nvidia display driver service should that be disabled too?

A while back I remember someone mentioning motherboard manufacturer's software causing sleep. If your non-Microsoft services are disabled too, I guess it is not the issue.

I would try changing to another power plan first and disabling display sleep. Or make a custom power plan with it disabled.

I am not sure if power settings work in Safe Mode but you could try there too.

Yes, disable all non-MS services, this is for troubleshooting. You can enable as easily.
