    Hey all,

    I have a Clevo P370sm (branded as Scan) i7 4700MQ, 8970m Crossfire, W10, UEFI, 18.10.1 (problem happens with official/beta drivers)

    At some point, the laptop display is no longer being detected by Windows, it works when it boots up but will not be detected when inside the OS.

    I've searched high and low on the internet but can't find anything, or I'm searching the wrong things, anyone got any ideas? It's driving me crazy!

    Do external outputs work?

    Hi,
    It looks like your MASTER GPU is gone, and whenever the AMD Radeon driver is loaded, screen stays blank.
    Try to swap the GPU or run it with the SLAVE GPU in the MASTER slot to see what happens.

    You could also confirm by booting into safe mode, if it works doing that too then the card can't support any kind of load (Safe mode and bootup are rendered by the CPU and the GPU simply outputs it).

    Thank you both for your replies :D

    ****, I hope it's not! Is there any other way to see if it is the card that has gone? When I'm playing games both GPUs are being used, or at least GPUz tells me they are and CrossFire enabled, these are screen grabs from GPUz showing the activity and the overview of each card

    And yes, external outputs do work.. I was thinking of changing to 980s.. maybe this is a sign

    EDIT: Works in safe mode.. :(

    Odd, if external outputs are fine the card is likely fine. It seems like an odd conflict on the internal output. What panel do you have?

    How would I got about finding that out? I assume it's stock/default, I don't recall changing it when I ordered this

    There are many options, something like hwinfo or look in device manager.

    Strange that it works with old crimson drivers and not with adrenalyn... Did you unistall fully with DDU before installing new driver?

    It does suggest something has been changed on the display output front. Did you bug report to AMD? You could always @ terry on twitter.
