I'm having a weird issue with my computer screen (Qosmio Model X301-Q701)

The screen works fine until I enlarge a window with a lot of white or gray in it to larger than 80% of my screen or maximize it.

I will get transparent flashing horizontal lines that come across the screen. If the window is scrollable such as a web page, when I scroll the lines move with the page.

If I maximize a window with other colors such as solitaire or media center, it works perfect. The LCD and graphics card have been replaced within the last few months and it is not happening all the time (just on white or gray backgrounds) which leads me to believe that it's not a hardware problem.

I took a video with my cell () What you see is what I see when the issue happens.

Any ideas I can try?

I've updated my graphics driver to the latest and greatest already with no help.

Update: adjusting the brightness, contrast, and gamma has created a temporary fix but I would like to resolve this.

It sounds like the inverter is starting to fail. These can be repaired for around $50 to $150 for the parts, and about 1 - 2 hours for labor by a competent technician. That said, whenever troubleshooting potential monitor problems, it is best to swap monitors with another computer to see if the problem follows your monitor, or stays with the computer. If it follows your monitor, you know it is the monitor. If it stays with the computer, you know it is something to do with the computer, or its graphics solution.

Unfortunately this is a laptop.

Well, swapping monitors is out, but you can attach an external monitor and see if it happens on it too. Nevertheless, the price for replacing the inverter is the same on laptop LCD monitors as it is on desktop LCD monitors.

Here is a method for testing the inverter & backlight http://www.fonerbooks.com/test.htm

Ok I connected both a CRT and flat panel monitor to my laptop to see what would happen. Still get the lines on the laptop display, but not on the other two monitors.
