    Alright I just got a L502x with the 1080 screen which will take some time getting used to :D

    One problem/concern im having;
    how does the combination on intel hd accelerator and nvidia work?

    When i right click on the desktop i see options for both intel and nvidia, when I connect my laptop with hdmi I see nvidia's options more. I ran a system requirement test and it said I have the intel hd. How does all this work, is there a option to turn off one or the other? :confused:

    The DisplayPort and the internal display are hooked up to the Intel frame buffer. The HDMI port is hooked up to the Nvidia frame buffer to allow 3D output. The Nvidia card is also hooked up to the Intel frame buffer, allowing it to render content for selected applications and merge it with the Intel-rendered content.

    The Nvidia driver is 'in control' in the sense that it determines whether and what gets rendered by which card. You can in essence turn one or the other off by setting it to always use the integrated or Nvidia card.

    The optimus technology on the Nvidia card allows it to remain idle while the Intel takes care of simple graphics, thus using less power, generating less heat, and less noise from the fan (plus a low WEI score).

    Then when you play a video, or games, etc., the Nvidia kicks in & off you go. Make sure your drivers are up-to-date & you will see a tray icon when the Nvidia is working - although the fan also gives it away. :)

    Cheers, Greg.
