Question XP Pen 12 Pro Works on Laptop but Not on PC (with GPU)

[Jbeen]

Hello ^^

I bought an XP Pen 12 Pro, and it works perfectly on my laptop. I also checked the cables, and they seem fine.

However, on my desktop PC, the display doesn’t show anything, though it still functions as a regular drawing tablet (like the non-display ones). I also have a GPU, and my PC recognizes the tablet as a second monitor.

When I power on my PC, the tablet displays the boot screen, but as soon as the "Welcome" screen appears on Windows 10, it goes blank. The same issue happens on my friend's PC running Windows 11. However, when I boot into safe mode, the tablet works—but my main monitor goes blank. If I boot normally, my main monitor works, but the tablet doesn't.

For reference:

• The XP Pen's HDMI is connected to the GPU, not the motherboard.
• The red USB (for Tablet's power supply) is plugged into a wall socket.
• All my PC’s USB ports are working (tested with a USB stick).

Fixes I've tried so far (none worked):​

• Reinstalling/updating the GPU driver
• Reinstalling/updating XP Pen drivers
• Changing resolution and refresh rate
• Buying a new 3-in-1 cable
• Buying a DisplayPort-to-HDMI adapter
• Switching between extended and duplicate displays

Any suggestions on how to fix this?

can you change settings in the installed driver menu?
is driver 4.0.6.241211 installed?

set the resolution to 1920x1080
set the tablet monitor in windows to monitor 2 and extend the desktop to it in windows settings
are you using the red cable with the extension cable or a direct cable USB-C to USB-C to wall plug?
try plugging the red cable to your pc
