Cintiq 13HD 'no input signal' on Mac

Postby Geeblets » Tue 17. Apr 2018, 16:13

So I've had a Cintiq 13HD for about 5 years, I've always connected to my Mac via HDMI to DisplayPort adapter, and it's worked fine the whole time.

I got a newer Mac a couple of weeks ago, and had to buy an HDMI to USB-C adapter to connect to my new computer. This worked fine for about a week, when suddenly one day, the display stopped being recognised and now it just says 'No input signal'

The tablet itself still works like an Intuos, but it won't work as a second monitor.

I plugged it back into my old Mac with the old setup that has always worked...to find it just says 'no input signal' again.

I assumed it could be a faulty tablet or 3-in-1 cable, but when I plug it into a games console (without an adapter) the cintiq acts as a monitor just fine.

I then thought that maybe my adapters were faulty, but both work perfectly when plugging a different monitor into both computers.

So it seems like it is specifically the interaction between this tablet and a Mac (I have tried 3 different machines) that's problematic.

I'm on macOS High Sierra, all updates installed. I have tried updating to the latest wacom driver, uninstalling all wacom drivers and doing a clean install, installing an older driver, unplugging all cables and re-securing....but NOTHING works!

If anyone could help me I'd massively appreciate it, this has been going on for a week now and support don't seem able to help!

The Wacom driver handles only the pen input and is not involved in the display. You should see a picture without any Wacom driver. - 'No Signal' means that the unit is not seeing any video signal from the computer - This can be a problem of the cable, the adapter or the input connector and electronics on the Cintiq. (On Windows machine it can be that the second display is set to be inactive.) - So check the Macs display preferences: Does it see an external monitor ? And if so use proper resolution ? Same resolution setting as on the games console ? (If one of the connector pins or wires is faulty, only lower resolution might get through).

Hi, thanks for your reply.

When plugged into a Mac (I have tried 3 different machines) it doesn’t recognise it as an available display at all. Even when clicking the ‘detect displays’ button in display settings.

Plugged into a PC without any adapter it isn’t recognised either. The second display was set to mirror (also tried extended) and set to the correct resolution for the cintiq.

The 3-in-1 cable was brand new, as I was advised to buy a new one, and both adapters (usb-c to hdmi and DisplayPort to hdmi) work perfectly when used to connect other monitors to my machines.

I have the exact same problem with my 22HD Touch- it worked for years then quit suddenly. I didn't change or adjust anything.

It still works as an Intuos Tablet, but no display.

I've tried it with 2 different computers, 3 different adapters, 3 different video inputs (HDMI, Mini-DVI, USB-C) and three different OSes (El Capitan, Windows 10, High Sierra).

Apparently Wacom wants almost $1000 to repair this. I've been using Wacom products for almost 2 decades now, I think it might be time for me to move on to something else more stable for my daily work.

It can be expensive if the LCD panel needs to be replaced - as its bonded with the digitizer and electronics, you can only exchange the complete unit. The service center will check, if that is necessary or if the problem is somewhere else (connector, cable, etc).
