    Whenever I turn on my laptop or open the lid my screen does an annoying flicker for several minutes. It is fine after a while but it is very annoying and it has been getting progressively worse. Is there anything that can be done or should I send it in to get repaired.

    On that note I have been thinking about upgrading my LCD to a 1920x1200 display. How easy is that to do?

    P.S. - The flicker may be the backlight?

    Thanks. I think it is the LCD since I can clearly see a color difference when I have light behind me (natural usually) and the screen has just turned on during a cold boot. Nice to see that I don't need to tear it apart. I don't want to replace the stock heatsink stuff with ICD7 quite yet.

    if you're changing the screen you should change the inverter and the display cable too to be in the safe side

    I could change the inverter but I don't think the display cable is at fault here. Even then I would need to tear apart the laptop to get to it which I won't have to do for just the inverter and lcd screen. Even then I think it is more likely the lcd and than the inverter but I could replace it anyways.

    EDIT: The one place I am looking at requires you to send in the laptop if your existing screen works. Wonder why. Anyways they have the only glossy one that I could find for my laptop.

    My resolution is ALREADY 1920 by 1200...
    I upgraded to Win7 Business and I instantly unlocked it on this 17" screen...

    Flickers... Hmm, I used to have those when I alt-tabbed between full-screen / non-full-screened applications.

    I would check your graphics settings to see if it's optimized for performance, and change some of them around. See which ones work best.

    BTW - the monitor on the 7805u is 17" WUXGA+, not WXGA+.

    It does it on a cold boot. In other words in the BIOS where the graphics drivers/settings would not apply.

    EDIT: Some 7805u models came with 1680x1050 or 1920x1200 displays in early releases. This was most likely due to them running out of the 1440x900 displays and still needing to produce more units so there was a factory substitution. Mine has the WXGA+ 1440x900 display that is supposed to come with the unit.
