Windows 7: Monitor goes to sleep when hibernate set to NEVER

Monitor goes to sleep when hibernate set to NEVER

2 hour hibernation for both CPU and monitor worked perfectly for about two weeks, waking up with a touch to the
spacebar. Then a few days ago the monitor would not wake up but the computer did. Now if I turn off the AC
power to both units and then re-boot the monitor will turn on but will go back to sleep in about 15 minutes with
the blue light blinking. The computer will complete a DL or backup with monitor sleeping so it appears OK.

Checks so far:
1. Updated drivers for both monitor and video card with latest available. Also updated chipset and BIOS (504).
2. Swapped monitors between computers and the problem went to the second monitor. Main monitor worked all day
on second computer.
3. Spoke to ASUS tech support and was told that the monitor is controlled by the OS. Suggested I enable ACPI 2.0
support (default disabled) and disable ACPI APIC Support (default enabled) in BIOS. Won't boot to OS when
ACPI APIC Support disabled.
4. Found a few similar cases on the Internet but no solutions.
5. Even tried turning off hibernation and setting monitor timeouts in the Powercfg using CMD prompt.
6. Re-installed OS, big mistake as it took several hours to get re-registered.
