Screen issue with my xp-pen artist 12 tablet

Hello, I have a problem with my XP-Pen Artist 12 tablet. When I plug in the cable (a special cable with a male HDMI, two male USBs, and a power connection), my tablet is automatically recognized by the computer, I get a Windows notification, the indicator light on my tablet turns on, but the screen of my tablet does not turn on even though the touch function works, my stylus is detected and I can move the cursor. To be honest, I think it might be an issue with the HDMI side of the cable, but it's also possible that the screen of my tablet is broken. I don't know how to figure it out or how to fix it, so I'm hoping for a solution to my problem.
