Windows 10 Pro 64 bit, ATI Radeon HD 5770 with latest driver (and Catalyst Suite), Monitor: LG Flatron E2360.
Turn off display: after 5 minutes
The screen does turn off but wakes up again almost immediately. The second time around after another 5 minutes (or whatever other time I set up, it stays off like it should. Is it caused by buggy driver? Anything I can try? Any ideas would be appreciated.
