When you draw, watch videos or browse webpages on the Huion Kamvas Pro 16 (4K)/Kamvas Pro 16 Plus (4K), you may see the display keeps freezing. This issue may be related to your graphics card and refresh rate settings.
To resolve this issue, follow the steps in the methods below.
Method 1. Make sure your graphics card supports 4K @ 60Hz
According to the industry standard, if there is an HDMI 1.4 port on your graphics card, your computer can run the Kamvas Pro 16 (4K) @ 30HZ. But the display may be freezing when you draw, watch videos or browse webpages on Huion Kamvas Pro 16 (4K). So we recommend you use a graphics card that has either an HDMI 2.0 port or DisplayPort 1.2 or later connector to support 4K @ 60HZ.
For more information, please refer to the below link.
Method 2. Make sure your computer is running @60Hz
If your graphics card supports 4K @ 60Hz, but the display still freezing. Please check the refresh rate settings on your computer.
Step 1. Select the Start button, then select Settings > System > Display > Advanced display settings.
Step 2. Under Refresh rate, select the rate you want.
Step 1. Choose Apple menu > System Preferences, then click Displays.
Step 2. Press and hold the Option key and select the Scaled button. The refresh rate menu appears.
Step 3. Click the Refresh Rate pop-up menu and choose a refresh rate.
