Hi everyone,
I’m having a strange issue with my MSI MAG 273QP QD-OLED X24 and wanted to check whether anyone else has experienced the same behavior.
System and monitor details:
  1. Monitor: MSI MAG 273QP QD-OLED X24
  2. Current firmware: FW.120
  3. GPU: NVIDIA RTX 5070
  4. PC connection: DisplayPort
  5. Nintendo Switch connection: HDMI 1
  6. Resolution/refresh rate: 2560 × 1440 at 240 Hz
  7. Adaptive-Sync: On
  8. DSC: On
  9. Auto Scan Input Source: Off
  10. HDMI CEC: Off
The monitor generally works normally while it remains on one input. The problem occurs whenever the display pipeline needs to reinitialize.

Examples that can trigger the issue:
  • Manually switching between DisplayPort and HDMI 1 through the monitor’s OSD
  • Turning Adaptive-Sync on or off
  • Changing another monitor setting that temporarily blanks and reinitializes the display
  • Occasionally changing refresh-related settings
When the issue happens:
  • The screen goes completely black
  • The OSD no longer appears
  • The joystick becomes unresponsive
  • There is no “No Signal” message
  • The monitor’s LED usually remains solid white
  • The monitor does not recover by itself
  • Disconnecting and reconnecting the monitor’s power restores it
This is not being caused by automatic input switching from the Nintendo Switch. I am manually changing the input through the monitor menu, and both Auto Scan Input Source and HDMI CEC are disabled.

I have already tried:
  • Updating to FW.120
  • Performing an OSD factory reset
  • Disconnecting all HDMI/DisplayPort cables and power
  • Leaving the monitor unplugged for several minutes
  • Holding the monitor joystick/power button while disconnected
  • Reconnecting only the PC through DisplayPort
  • Testing with the Nintendo Switch disconnected

    Please let me know if you have experience this issue or is there any resolution for this.

Hi,
Do you use multiple monitors with a dedicated graphics card? If so, please try setting the "Power Button" option to "Standby" in the OSD menu using the monitor's physical buttons or Navi Key. Then check whether this resolves the issue.
