Hey guys, I have a Gateway FX Desktop Replacement and I bought it refurbished, as suggested by another techie.. (For the price)

As soon as I bought it, it would artifact on black background. I sent it in with its 90 day refurbished warranty, and they replaced the motherboard, cpu, and integrated 9800GTS

Since then, it has operated smoothly until today. I turned her on and I noticed the same distortion on black and similar colors. I got so frustrated I shut her off immediately hoping my eyes were playing tricks. I have a third party warranty with her, but I don't know if they will be able to replace it.. ;_;

Can someone help me out? =((

Tell us more, in more detail... model and configuration first.

Eh. Model #P7811FX

I found out what it was doing. It has a bad screen. If I turn the gamma up, the artification disappears. But if I turn it down, it gets worse. The lower the gamma the worse the artification.

Looks like I'll be shipping it off...

Thanks for the update.
What brand and model is the screen?

I don't know actually. Whatever comes with that laptop. I just know it's a Gateway 17" 1920x1280 LCD Laptop screen. =D
