    Exclamation Dell monitor flickering (shutting down twice) when devices connected via HDMI-with weird HDMI error

    Hello, I really can't figure what is going on, so I will just say it. My monitor started around 2 days ago to flicker; it happens around every 1 minute and it flickers twice, in very rare cases 3 times. It is not like going blank but more like a brief shutdown or detecting of a source. The monitor is a Dell IPS P 23.8" series, bought it around 3 weeks ago, no problems, and it is connected via DVI to a Asus HD6950 card. To the same card but via HDMI is connected a Yamaha AV receiver and to the AVR a Samsung TV also via HDMI.
    Didn't get any problems until recently when due to some power surge (got a UPS, protects everything, but shut down the TV and the AVR) the TV didn't seems to recognize it's HDMI in. Updated firmware, reset, swaped cables and everything was fine. But I still got the issue with my monitor; it didn't appear at the same time though! Maybe due to updates.

    I have something in the logs and it seems closely related:

    12/28/13 04:36:17 PM ALSA hda_eld.c 34 HDMI: ELD buf size is 0, force 128
    12/28/13 04:36:17 PM ALSA hda_eld.c 51 HDMI: invalid ELD data byte 0

    it just keeps on repeating, I do use the HDMI for audio. But it doesn't matter if I stop the TV and the AVR the monitor still flickers. Also I got intermittent sound out via HDMI (seems more one or another, the monitor and the sound) as I can see clearly how the AVR stops decoding signal.

    In xorgs logs I get this which confirms it detecs the monitor at that time:

    Default Re: Dell monitor flickering (shutting down twice) when devices connected via HDMI-with weird HDMI er

    Extra info: When I connect the AVR and the TV - it does this on their side. But the TV now is shutting down for minutes (no signal) and starting randomly on his own. It makes no difference if setup some other multi dsplay sheme in ACCAnd I see this new information:

    DAL force OS to Re-enumerate Modes xorg

    Anyone encountered something like this? I hope this is a bug (god forbid some hardware problem!) somewhere in the recently updated X.Org X Server 1.14.3.901 (1.14.4 RC 1) or amd fglrx driver (OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 6900 Series OpenGL version string: 4.3.12618 Compatibility Profile Context 13.251)
