Calibration issue

So I was gifted a Huion GT-185HD Interactive IPS Pen Display tablet some time ago and I got (what I believe to be) everything set up: I have the HDMI cable plugged into my computer, the USB cable, and it's plugged in for power.

The issue I ran into is that when I turn on my pen and touch the screen with it, the cursor bugs out at the top of the screen (at about URL level) and doesn't go any lower than that. I believe I have the right Drivers installed, and on top of everything I can't calibrate it due to it bugging out.

I thought the issue might've been the cords or the pen, but I got new ones and the issue stayed the same
