    Windows 10 unstable in dual screen setup displayport + hdmi

    I just changed my system from an intel i5 2500k to an amd r5 1600 and with almost the same hardware (only changed cpu, motherboard, ram and switched to a m2 ssd as windows drive) and windows version (freshly
    resinstalled) windows crashes when I turn my displayport screen on again in dual screen setup with an hdmi screen.

    System Configuration:

    Motherboard: MSI X370 gaming pro carbon

    BIOS: 7A32v17 (AGESA 1.0.0.6)

    CPU: AMD Ryzen 5 1600

    Memory: 16GB DDR4 3200 (G-Skill F4-3200C16D-16GVKB)

    GPU: MSI RX 480 gaming x 8GB

    VBIOS: 015.050.000.000

    GPU Driver: 17.7.1

    OS: Windows 10 Pro N x64 (15063.483)

    Steps to Reproduce:


    • Plug into gpu ports: BenQ XL2730Z @ displayport, Philips 273P3LPHES @ hdmi

    • turn on pc and displays, wait for windows login

    • turn off displayport display

    • turn on displayport display

    • what now happens: displayport display stays black (no signal), hdmi display turns black (no signal), pc unresponsive

    • after 10 - 20 seconds pc reboots automatically
    Expected Behavior:

    displayport display should turn on normally without crashing the pc in dual screen setup

    Actual Behavior:

    displayport display causes crash when turned on again

    Additional Observations:

    Turning the hdmi monitor off and on does not crash windows even if displayport display is plugged in.

    Unplugging the hdmi monitor and turning the displayport monitor off and on does not crash windows.

    I used the exact same hardware and drivers before with an Intel i5-2500k and an Asrock Extreme 3 gen 3 without these issues. Windows and drivers were completely reinstalled though after switching to Ryzen.

  3. 144Hz monitor working on windows 7 but not win10

    According monitor's manual 2560x1440@144Hz is supported with both DisplayPort and HDMI 2.0. If you cannot reach this resolution following steps in manual you may ask a help from BenQ or Gigabyte support.

    Cannot change display to 144hz, keep getting administrative error

    Thanks for the reply, it is 144hz compatible as it's been at 144hz for a year now and it's a gaming monitor.

    That said, I found a weird solution.. something that has kind of worked before when I've had similar issues. Other displayport cables don't work, but I used an HDMI cable on the 2nd monitor and suddenly it works, and
    my main monitor switched back to 144hz. This doesn't sound like a hardware issue, something related to windows or my drivers potentially?

    I would like to run both as displayport because it allows my 2nd monitor to run at 144hz as well, any ideas?
