    Hello everyone,

    I apologize for my English. I'm Italian.

    My pc has a very annoying flaw... during normal use of the pixels you see crazy. You see the annoying white pixels.
    There are not many but especially for graphics work it's badly.

    I already restored the PC once installed the ATI driver from the Toshiba official website but the problem continues.
    I also tried the drivers from the amd site but the problem persists.

    If you can help the problem becomes much more pronounced after the return of the suspension. In this case, the desktop you see really bad with all the pixels in a mess.

    If you need additional information or tell me I can do tests as well.

    Thank you.

    Hi

    I’m not quite sure if it’s a internal display issue or maybe a graphic card problem…
    Therefore you should connect and external monitor in order to check what’s exactly wrong…

    Usually the graphic card is affected if the same pixels would appear on the second monitor.

    But if the picture on the external monitor would be OK, then the graphic chip should be ok too… and in such case the internal notebook display is faulty…

    But in both cases it would be expensive to fix the notebook because both parts are not cheap.

    the same problem also occurs if I connect to an external monitor.
    The problem manifests itself seriously when he returns from sleep (sleep mode) for several hours. After a few minutes of use then returns to work well alone.
    The PC is still under warranty (purchased 1 month)

    I attach 2 files to let you know what happens when returns from sleep mode:

    If the external monitor is affected too, then I would say that the graphic chip (graphic card) is affected.
    So this means that motherboard needs to be replaced. :(
