    First post, hope I am not necro'ing anyone's thread.

    The Issue: Dual monitors, secondary stays in D-VID Power Saving Mode and goes to black and flashes the standby light.

    Monitor Model: LG 24'' IPS LED D2343 (CINEMA 3D)

    Was working perfectly less than 24 hours ago, upon boot up this issue arose, attempted fixes to follow:

    Basic Fixes Attempted:

    1. Classic restart.
    2. Removed screen connections, power and DVI.
    3. Swapped Ports on the actual GPU between main and secondary monitors, main monitor fires up no problem.
    4. Used the Monitor and cables with a different PC- The Monitor worked perfectly.
    5. Reinstalled GPU Drivers.
    6. Cleaned out the tower, dust etc.
    7. Checked and re-checked as many settings as possible on W10, everything from Power settings to Display and Device management, this includes trying hot keys- like those used to project screens etc.
    8. Checked windows Update- fully updated.
    9 No dodgy software detected or any software installed lately.

    Intermediate Fixes Attempted:

    1. Removed and re-seated GPU, checked all connections, including RAM and PSU cords.
    2. Replaced Button battery on MB.
    3. Tried Display arrangement- no joy since it isn't event detected.
    4. Lowered main Monitors hertz/refresh rate from 144 to 60.
    5. Tried powering off everything and holding in power buttons to remove excess charge and reconnecting.

    Advanced fixes Attempted:

    1. Alcoholism.

    Potential 'Fixes' Not yet Attempted:

    1. Booting in safe mode and changing power based settings, ensuring no limit to power in any way.
    2. New cables (Redundant).
    3. PSU Swap.
    4. Different GPU running both monitors.
    5. Checking for any strange related BIOS controlling power settings, or MB Software.
    6. Incense and Chanting.

    Any suggestions in this matter would be fantastic, as I use the second monitor for Video Editing.

    Many thanks.
