Question about ViewSonic Computers & Internet
Hello I was wondering if it is safe to run my ViewSonic VA2342 LED screen from an old Belkin Battery Backup Rev B (those left behind att uverse gray ones.) As far as I know the Belkin is 12V DC, Btw I am using this because I bought the screen for $20 because it didn't have the power cable. So I tried it today and it ran perfectly fine just want to make sure it won't mess it up. I will of course run it with the backup battery plugged in not only off battery mode on the backup battery. In case you aren't familiar this backup battery is also usable plugged in so it does not always run off the battery.

This issue may occur if the signal from the video adapter exceeds the scan range of the monitor. The video adapter setting for updating the screen (the refresh rate) is incompatible with the monitor.
you should reinstall your video drivers in safe mode.
To restart in safe mode repeatedly press the F8 key during the computer startup. This will bring a menu where you'll be able to choose safe mode.
LCD monitor 60 - 75 Hz

Tips for a great answer:
Windows Advanced Options Menu
Please select an option:
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Start Windows Normally
Return to OS Choices Menu
Use the up and down arrow keys to move the highlight to your choice
select safe mode with command prompt
Click start run type cmd press Enter
black screen should open DOS mode
this will vary depending on your operating system
type in net user username
For eg. If you want to change administrator password , type net user Administrator
it will prompt you to enter the new password
enter the new password and the password is changed
if this fails you will need to
Select safe mode with networking to download
you could download all of these or just one save them to a usb drive for later use if one fails to remove the password
A CMOS BIOS password recovery tool
Editors note: This tool should only be used by experienced computer users. Please see the enclosed read me if you would like to run it from Windows. Failure to follow instructions (from Windows) will cause your anti-virus to flag this as a virus.
