    Ok guys, here's another one.

    So I've got a 52" Sony Bravia that I hook my lil M11x to to watch movies and whatnot. Problem is; after 10 - 15 the TV screen loses signal and blanks out. At first I thought that it might be my screensaver kicking in but then the TV loses all signal and my TV goes to the menu screen which says "No Signal."

    This has been going on for a month now and it's really bugging me. Is this a video driver problem, defective hdmi connection, or what? I'm running the latest Intel HD driver and Nvidia 260.99.

    change when the display is turned off in advanced power options (change everything to never going off) for plugged and unplugged

    for me I made a custom power plan just for when I have an external display plugged in so this doesnt happen

    I never had this issue with my Sony Bravia. Only reason Is topped using my m11x is no hardware acceleration from the video card for iTunes.

    I always set the "never turn off" when plugged in though so that may be it.

    What drivers are you using? You can set your M11x to use the GPU for iTunes and such either in the nVidia config or from the right click context menu, at least on drivers 256 and up if I recall correctly. I'm on 258.96 and I can run iTunes with the GPU for HD movies when I want to.

    I'm using the community drivers from here right now. I didn't think iTunes supported acceleration via video card, will have to look into that.
