Having no image in your Pen Display can be caused by a few different reasons.
Does the Wacom Pen Display have power?
All Wacom Pen Displays require their own power source. If no power reaches the device, it will no be able to function.
- Make sure the device is connected to the power adapter. Even when not connected to a computer, the unit should be able to turn on once connected to the power adapter. Press the power button and confirm if the power LED lights up. Check your device's manual if you are not sure.
- Once connected to a power adapter if the unit does not power on, check the cables and replace them if possible. If that doesn't work, please contact Wacom Customer Support.
The display has power, but "no input signal" message is displayed and the device goes to sleep after a while?
If the Power LED is on and a "No Input Signal" message is displayed, this typically means the video signal from your computer is not reaching the Wacom Display.
Make sure the tablet is connected to the computer correctly
Most Wacom Pen Displays use both a USB and video cable i.e. HDMI and Display Port (or DVI in some older models) to connect to the computer. Some newer models can use only 1 for both USB data transfer and video signal transfer via Thunderbolt 3.
USB transfers data from the Pen Display to the computer and the video cable will receive the video signal from the computer for the display. Thunderbolt 3 connections can support this with a single cable.
- Make sure the cabled are securely connected. Unplug all cables and check if there are any broken pins or dirt before plugging back in.
- If possible, remove any adapters and plug the cables directly to the computer. If an adapter is absolutely necessary to connect your device to the computer, test the adapter with different devices to be sure the issue is not with the adapter. Adapters can fail over time. Wacom recommends Startech and Kanex adapters as we have found them to be the most reliable when using with a Wacom Pen Display.
- Some models like the Cintiq Pro 24 and Cintiq Pro 32 provide different options for video connection. If the connection type you are using fails to deliver a signal to the display, please try one of the other options i.e. if HDMI doesn't seem to work, try DisplayPort, or Thunderbolt 3
- If you are using a Thunderbolt 3 cable to transfer both USB data and video signal, make sure the USB-C port in your computer is actually able to support this. Not all USB-C ports will support this.
Test another display cable
- Most current Wacom Pen Displays have detachable cables. Follow the steps in the manual for your tablet to remove the display cable and test with a new display cable.
- Some Wacom Pen Displays like the Wacom One and the Cintiq 16 use proprietary cables. If you suspect your cable is defective, contact Wacom Customer Support
Changing display settings
Once connected to a computer and if "No Input Signal" message is still shown, the issue may be a display setting in the operating system. You will need a second monitor to try the steps below.
- Windows: Right click on the desktop and select “Display Settings”. In display settings, set the option for multiple displays to “extend these displays” and click apply. Once selected if the Cintiq shows under the identified monitors on the top, select the Cintiq and make sure the resolution is set to “Recommended.” If the issue continues, please contact Wacom Customer Support.
- Mac: Open system preferences and select displays. A display window should open on each display. On the main display, un-check the “Mirror these displays.” Next, make sure the resolution for the Cintiq is set to “Best for display.” If the issue continues, please contact Wacom Customer Support.
The display has power, but the is nothing being displayed on the screen and there is no active backlight in the LCD?
- If the unit powers ON, the LCD backlight should activate and after a few seconds, a Wacom logo should be displayed. If this doesn't happen, then contact Wacom Customer Support
