Kamvas Pro 12 "No Signal", "Sleep Mode"

I bought the Kamvas Pro 12 earlier this year (May 31st), and I have had zero issues with it up until a few days ago. It's been giving me "No Signal" and "Sleep Mode" messages every time I turned it on.

At first, I thought this was simply a matter of updating because I'd never updated the tablet before, so I updated it and it still didn't do anything. I restarted my laptop, reinstalled the driver, and even double checked everything- nothing is working.

To make it even more confusing, my computer recognises my tablet as an entity, but not as a second monitor. It recognises when the tablet is plugged in and not plugged in, but I can't duplicate the screen and when I look into the settings it isn't recognised at all. 


I really need answers to this. Has anybody else been having this issue? 


If it helps my laptop is a windows 10 HP laptop as well.

the problem wasn't in the cable. It was drivers but not huion or video card drivers. My laptop wasn't recognise a tablet as monitor and was show it just like usb device. So i resolved it this way:

1. Go to device manager

2. Find your device (my was in usb device)

3. Go to properties and open details than choose compatible ids. Appear something like this USB\VID_0BDA&PID_0129&REV_3960 (not exactly like this)

4. Just copy it and paste in google, it find a driver. Download it and install. Hope it will work for you and sorry for my english.

Hi Orliza! Thanks for help but unfortunately it doesn't work for me :с I resolved this problem in other way
