    Dell U27HM flickering/quarter image/black with smeared colors

    Hi all

    Wondering if I could get some insight on a Dell U27HM. First turned it on and the image was completely black. I later realised that if I dragged a window from one monitor to (the broken) other one then smeared colors would appear on the bottom 75% of the screen. After being on for several hours the top part of the screen started flickering showing an image (I have a video of this) and then suddenly the image appeared albeit rather fuzzy in the bottom 75% - image attached - and some hour later it now appears normal

    I do have two of these monitors so a compare/swap diagnosis would be possible, just wondering if anyone has any ideas where to start?

    KOGAN - KALED58RT9220SVA - Image flickering when in Energy Saving mode
    by TrueSword88
    Hi All

    I have a KOGAN 58' LCD Panel that 'flickers / pulsates' when in energy saving mode.
    I've reset the unit to factory default & rerun the initial setup but no change.

    IF I choose any other mode, example: Standard, flickering disappears.

    I've downloaded the most recent FW for this model from Kogan's website & re-flashed. This initiated a full wipe of the unit, which subsequently led to the setup all over again, however, the issue still remained - screen flickering but only when in 'energy saving' mode.

    I've taken the unit apart,...
