My monitor keeps switching off and saying it is "Out of range"?

Question

Hi, well after a couple of minutes of use, my computer either freezes completely or the monitor switches off, then when i switch it back on it says something like: "Attention Out of Range, H:68.8Khz V:170.0Hz". Then when i restart the computer, even in safe mode it freezes during startup. I've tried putting the refresh rate right down to 60Hz but it's still happening. My monitor is an AOC CRT type, I'm using Windows XP Pro, my processer is an Athlon XP+ 3000, and the video card is a Radeon 9800 Pro. Thanks.

Answer 1

OK, you knew it's fresh rate issue, but if it reoccurs reinstall video card driver, even replace the card as a last resort, driver don't keep refresh rates.

Answer 2

Several things to test. You will need a "known" working PC (one you know is working correctly).

Try the Monitor on a different PC. If the same results, the Monitor is bad. If the monitor has no problems, go to the next step.

Is the Card in a AGP slot? Try the Video card in a different PC. If the problems occurs in the other PC, the Video card is either not configured correctly (update Drivers) or the card is bad or the AGP slot is bad. The only way to test the AGP is trying a "known" good Video card or taking it to an authorized repair shop.

Is the Card in a PCI slot? Try another slot. If same result, try in a different PC. Otherwise, see step above.

When you try to start your computer in Normal mode, and you are using a new monitor, the screen display may appear garbled, or you may receive the following error message:

Signal out of range

CAUSE
This behavior can occur if the signal from the video adapter exceeds the scan range of the new monitor. The video adapter setting for updating the screen (the refresh rate) is incompatible with the monitor.


RESOLUTION
To resolve this behavior, either change the refresh rate, or change the video adapter settings.

To change the refresh rate:
1. Restart the computer, and while it is restarting, press F8 until the Startup menu appears. Press 3, and then press ENTER to start the computer in Safe mode.
2. Right-click the desktop, click Properties, and then click Settings.
3. Click Advanced, click Adapter, and then click Adapter Default from the Refresh Rate list.
4. Click OK, click OK again, and then click Yes to restart the computer in Normal mode.
You can set the colors and screen area to your preferences under Display Properties.

Answer 4

I think there is some problem in the VGA cable or connector between the System and Monitor.

Answer 5

first off try reinstalling the drivers for the video card, and make sure your monitor is set to display settings that it can only use

Answer 6

try to change your monitor first,if the same message occurs then thats the time to suspect your vga system on your pc.
