Monitor Displays Wavy Lines

[trichard]

Here's a probably an easy one for you whizzes out there... I start up an HP with Millenium. The splash screen shows up fine, but when it gets to what is suppose to be the desktop the monitor displays a constant wave of lines. How do I solve this problem?

Check if your vga cable is properly inserted onto your VGA card. Make sure you turn the screws into the vga card.

If that isn't the problem then reinstall your vga cards display drivers or get new ones on the internet.
If that doesn't help than your monitor might be getting interferance from a mobile phone or a radio.

putting the monitor too near the electrical source (wall socket or non protected adapter) will cause this problem too, other than that i agree with everything Kocky suggested

You might want to see what else is on the circuit your pc is plugged in.

You may also want to check and make sure you are using a screen resolution and refresh rate supported by your monitor. Boot up into safe mode (press F8 before the ME splash screen and choose safe mode from the boot menu) and if your screen does not have the wavy lines, chances are you are using an unsupported resolution and/or refresh rate. Go into the control panel, and open up the display properties. Click on the settings tab and change your screen resolution to 640 X 480 and 16 colors. To change your refresh rate, click on the advanced button at the bottom right hand corner of the display settings window. Click on the monitor tab. Change the screen refresh rate to 60 Hz, or adapter default. Once you reboot, you will be in a default vga mode that is compatible with all monitors. You can then go back into the display properties and adjust the setings to your liking. Just make sure you hit apply so that it tests the mode you select first. If the screen goes wavy again, wait a couple seconds and it will revert back.
