Hello jingaling, Thank you for joining this Intel Community. To better assist you, we would like to know if you are using a daisy-chain connection: 1. Intel® NUC (USB Type-C) to main monitor (DisplayPort*). 2. DisplayPort* Out on the first monitor to DisplayPort* In on the second monitor. If your connection is different, please let us know. It is worth mentioning that DisplayPort* 1.2 MST should be supported by the monitors. I was not able to find the monitor specifications with the model you posted. If possible, please provide us with a link or check the manual. Also, try enabling DisplayPort* 1.2 on your monitor. Wanner G. Intel Customer Support Technician Under Contract to Intel Corporation

Hello jingaling, First, please try doing a clean installation of the latest graphics driver: 1.Disconnect your unit from the internet. 2.Uninstall both the Intel Graphics driver and the Intel Display audio driver. To do this, please follow the steps on the link below under these sections: -Uninstalling the Intel Graphics Driver via the Device Manager Method -Uninstalling the Intel® Display Audio Driver or the Intel® HDMI Audio Driver via the Device Manager Method. https://www.intel.com/content/www/us/en/support/articles/000005598/graphics-drivers.html 3.Restart your computer. Go to the device manager and check if Windows installed another version of the graphics driver. If it does, please remove it and restart your computer one more time. Repeat the process until you get the Microsoft Basic Display Adapter. 4.Once you do, please proceed with the clean install of the latest graphics driver: For Intel® NUC Kit NUC7i[x]BN Intel® HD Graphics Driver for Windows® 10 for Intel® NUC Kit NUC7i3BN, NUC7i5BN, NUC7i7BN Version: 24.20.100.6286 (Latest) https://downloadcenter.intel.com/download/28208/Intel-HD-Graphics-Driver-for-Windows-10-for-Intel-NU... 5.Once the latest driver has been installed, you may enable the internet connection again.
