    Hello,
    I encountered an issue just now when watching a movie from my Acer on my Philips LCD - after a random amount of time (5 to 30min) the screen turns green for a few secs and then displays colours only inverted. After some research I found out it might be a Philips TV Firmware issue: Problem with wrong colors when connected via HDMI to Philips TV

    The main issue seems to be an hdmi sync problem with the audio signal - I'm no techie in that matter - an audio signal in SPDIF format appears to cause the problem and a possible solution might be to turn to "HDMI passthrough" signal, but I got no idea how to do this.

    .. Ok I just checked out the Audio settings as I couldnt find anything in the ATI control panel - I suppose its something about the "Digital Audio (S/PDIF)" device, but again, I'm not sure what to look for as I cant see a "passthrough"-setting.

    Any help is appreciated!
    Thanks and Greetings

    - Oh and btw, is it possible to make the Intel Graphics the standard graphics even when plugged-in?

    About the switchable gfx, right click on desktop,select switchable graphics option,plug in the ac adapter,select power saving graphics and disable autoswitching to performance graphics when ac plugged checkbox.
    About the hdmi passthrough,cant help really,check under sound hardware in controlpanel.

    Thanks for your reply, but I dont got a "disable autoswitching to performance graphics when ac plugged"-checkbox.

    Which is really driving me nuts though is the HDMI out. Now the sound wont even be played through HDMI on my TV! It's always played through the notebook speakers. Problem is, my Notebook doesn't detect an HDMI audio device I could set as default in the Sounds Control Panel (just Speakers and Digital Audio SPDIF). I installed the Realtek Drivers Audio_Realtek_6.0.1.6050_Win7x86x64 or R2.43 as it's called in the install wizard.

    But the only thing this does is installing this gosh ugly Realtek interface and totally screws my microphone, which already had annoying loud crackles already - and with those drivers I sound like an underwater robot with speech impediment. There are no further options for HDMI.

    I honestly don't know what else to do as I already tried so much and nothing helped - sigh!
