My ViewSonic computer monitor keeps displaying a Vga Not Support Message upon booting then the message Out Of Range comes up on a completely dark screen. Need Help

Signal OVER RANGE?
Monitor unable to cope with the frequency the computer is sending (for want of a better explaination.
Boot the computer to VGA mode and adjust the display settings, or boot to safe mode

try the lcd monitor on another PC, if the same message pops out, your monitor needs reprogramming of its A/D board, bring it to a LG service center..

if it works fine on another PC, try to boot your PC on VGA mode..

The maximum/native resolution for this display is 1024 x 768 @ 60Hz, you need to adjust your PC video resolution, it is too high right now for the Viewsonic to work. Hook up your old monitor and set the new resolution, otherwise bootup in safe mode (hit f8 key while booting up) and choose VGA support, set the new resolution, reboot.

The monitor will display out of range message because the PC video resolution is too high for the monitor to display, the new software may have changed or corrupt the video seting, try booting up in safe mode (hit f8 while computer booting up) and set the video resolution to 640 x 480, then reboot in regular mode, then reset the resolution to the native resolution of this monitor which is 1280x1024@60Hz.

Have you verified the video card in the computer with a different monitor? Does the going to sleep message come up prior th the monitor going dark? The bulbs are ok since you do see a picture for a short time. The voltage swing you see on the power supply is too large. It should always be 12 v + or- 10%.

Try booting to the ENABLE VGA mode off the F8 menu if you can get to the desktop and then you can go to display properties and see if you can reset the resolution to normal. If no go, try updating the video driver

The fix was pretty easy in the end.

Instructions are based upon Windows XP Pro OS.

Re-boot computer but inerrupt start-up by pressing F8 (option will vary between computers)

Select SAFE mode but with VGA option in order that the screen will actually display.

Once fully loaded click:

Start
Control Panel
Appearance and Themes
Display
Settings

Using the mouse cursor adjust Screen Resolution sliding scale until the ratio matches your monitor e.g. 1280 x 1084

Then click Apply and OK (important to do it in this order otherwise changes will not be saved)

Reboot as normal and the monitor should now display correctly.

..hi..just select menu on the front panel of LCD the find the option Auto then click Auto..good luck..Thanks...^_^

ya u enable vga mode hit f8 at start up in xp select vga mode ok resets u then use 60 hertz man and its native res ok only update drivers ect mark me ask fit ya ok thx nick

This problem may arise from monitor as well as from cpu.
First of all check it by unplugging the VGA monitor cable.
This will display the "Check Signal Cable" depending on the model of the monitor. But a message will appear rolling on the screen, if it is not a very old monitor.
If the message is appearing OK and green light is continuously on, that means ur monitor is working fine.
The problem may be with VGA cable or with the booting of CPU and probably the RAM. Recommended solution is to reconnect the RAM and then try, if u think u can do. Otherwise call a hardware engineer.
If there is no message and still the light is turning green and yellow. That means the problem is definintely in the monitor.

Thankyou,
Your well wisher
