  1. What resolution are you gaming at when connected to an external display?

    Also, are your drivers up to date?
  2. 1920 x 1080 on both screens (internal and external)

    i have also tried to update the drivers for my grafics card but without luck...
  3. If you didn't get your drivers directly from Nvidia, then go here for the latest drivers from Nvidia:



    If they won't install, please provide the errors generated.
  4. i downloaded them from nvidia and used they auto dectect service
    and what u are linking to are the wrong driver i have NVIDIA® GeForce® GT 555M 2GB DDR3 VRAM
  5. No they are the correct drivers. Look at the Supported Products tab on both links.

    Are you using 32-bit or 64-bit Windows 7? You have to use the version of the drivers for your version of Windows.

    Also, don't use the auto-detect. Just download and install the drivers.
  6. i use 64 bit
    i have tried to download and install to driver u gave me the link to but ut have not help at all :(
  7. This Asus model appears to support hybrid graphics (I can't confirm from looking at the Asus website):

    This is a power saving feature that lets you use the laptop's on-board Intel video adapter when less demanding tasks are running. When more demanding video tasks are running, the system will automatically switch to the Nvidia video adapter.

    If your system is not switching back and forth, it could be part of the issue. I am only theorizing at this point. Try this, look at your BIOS settings and see if you can disable the on-board video adapter (Intel) and then test your graphics speeds.

    Also, just as an aside, how does the system perform when you display to both the internal LCD and the external display at the same time?
  8. i have looked i BIOS and i can't find any video settings at all i have tryed google and i can see the adaptor from intel grafichs controller in device manager
    should i try that?
  9. Sure, you could disable it in Windows. That should force the use of the Nvidia adapter at all times. This will increase performance, but will decrease battery life.
  10. Also, if for some reason you lose all graphics upon restarting the system after disabling the Intel adapter in Widnows. Just boot into Safe Mode and re-enable the Intel adapter in Device Manager.
  11. i have tried to disable the intergrated Intel HD Graphics 3000 but without luck...
    i think i will contact ASUS to hear if i am the only that have this problem....
    thx u for all the help :)
  12. You are welcome. Good luck. Please post the results.
  13. will do :)
