Unit Type Price Difference

Why are the HDMI and mDP Luna Display units a different price than the USB-C Luna Display unit?

The USB-C Luna Display unit can be used on both compatible Macs and PCs, whereas the HDMI unit can only be used on compatible PCs and the mDP unit can only be used on compatible Macs.

How do I know which unit to buy?

If your PC supports HDMI displays or your Mac supports mDP displays, and you do not have both a Mac and a PC, those may be a better option for you. You can read more on how to choose your unit type here. 

Please note that Luna Display does not support the use of adapters. Luna must be plugged in directly to your primary computer.
