Thank you for viewing. I purchased this to output to two external displays with my M1 Macbook Air, but I'm selling it because I rarely use it. While you can add external displays through software processing, please note that if you use this device, you will not be able to play copyrighted videos (such as Netflix) including the built-in display. YouTube can be viewed.
