Luna for Windows: What unit type should I buy?
Luna for Windows is coming and will be available in USB-C and HDMI. If you already own a USB-C Luna, you should be able to use it with your PC once our Kickstarter is over and we begin shipping Windows units. At this time, Mini DisplayPort (mDP) will not be available for use with PCs.
The only difference between the two units is the port type. Many PCs have USB-C ports, and many have HDMI ports. If both ports can be used for an external display, you could purchase whichever one fits in with your workflow best.
