I've had this tablet for about 2 years, and I used it with my laptop with almost none of this issue.

However, after about a month of a break, I decided to plug it into a new PC after I downloaded the driver.

The pen works, it detects pen pressure and stuff too. But for some reason, I just cannot seem to detect it as a device as a monitor! I am using a Windows 10 and I have a decent PC. I have checked the settings and it just does not seem to work.

I also checked the Device Manager and there is nothing for the HDMI except for the main monitor that works.

Is there anything I can do?
