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 your graphics card has an HDMI 1.4 port, 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 with 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 and the display is 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 appropriate rate.
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 will appear.
Step 3. Click the Refresh Rate pop-up menu and choose the corresponding refresh rate.
