LCD Monitor Colour Flickering/Tinting

I bought an LCD monitor last Sunday and it was working fine until yesterday (Friday). Now, the colours pink and blue flicker (tint the screen) on and off. It's not a permanent tint, but the colours come on and off almost every second.

Previously, I had a CRT monitor which was permanently tinted pink or blue. I was told that the guns in the monitor were busted.

Things I've done:

- checked to see if the pins were bent
- unplugged and re-plugged the cables
- checked to see if the plugs were loose

My graphics card is pretty old, an nVidia GeForce 4 MX440 with AGP 8X.

I'm probably going to take the monitor back to the shop, but I want to know if there's any way I can determine the problem myself. Could it be the graphics card?

It's not exactly the same thing. The CRT was permanently tinted a deep pink or a deep blue. When I hit the monitor, the tint would either change colour or disappear temporarily.

With the LCD, the tint is faint and it comes on and off in a flickering motion.

I don't know what a multi-hookup is.

I don't have another video card, but when I tried switching the LCD plug from the GeForce card to the integrated card, the monitor wouldn't work. How do I check if the integrated card can support the LCD?

check the bios/setup for an option that you can 'toggle' over to onboard video....

I checked the setup, but there was no option to toggle to onboard video.

I don't really know how to open everything up and pull out the card either.

The problem has got worse - it's now permanently tinted blue.

I did try going to the Device Manager and disabling the nVidia card (with the LCD still plugged in to that card). The colour seemed to be fine, but everything was generally slow and crappy, with no right resolution for me to choose.

if you disabled the card in device manager how did you still have display? also i have read on a few articles and found there is something in some of the lcd's that goes bad and the screen will turn permanent pink, but i didnt see anhting about blue

where did you buy that lcd monitor? I would think they would test it for nothing. It would only take them about 30 seconds..

Beats me, but that's what happened.

I brought it back to the shop but they couldn't find anything wrong with it, so I'm guessing this means it's a problem with the graphics card - but what?
