Computer won't turn off monitor
New computer runs Windows 7 64 bit. After screensaver, the computer goes to sleep but will not turn off monitor. The monitor's own screen saver pops up instead of sleeping itself. Any thoughts would be greatly appreciated.
Keys to the Problem Computer won't turn off monitor
Is there any driver available for the monitor in the manufacturer website? If yes download and install it?
b. What is the "Monitors own screen saver" that you have referred?
Monitor should ideally go to standby mode when computer goes to sleep.
Method 1: Make sure that you have compatible drivers for the hardware on your computer.
This is one of the main reasons which causes improper sleep/hibernate and which results in computer freezes.

Method 2:A program or scheduled task might be waking your computer.
By default, Power Option settings do not allow scheduled tasks to wake the computer from sleep or hibernate.
However, some programs might awaken the computer if these settings
have been changed.
To prevent programs from waking your computer
1. Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.
2. On the Select a power plan page, click Change plan settings for the plan that you want to change.
3. On the Change settings for the plan page, click Change advanced power settings.
4. On the Advanced settings tab, expand Sleep, expand Allow wake timers, choose Disable for both when your computer is running on battery and when it's plugged in, and then click OK.
