Astropad Luna Display (HDMI) This allows you to use an iPad or Mac as a second display for Windows. I would like to sell it to those who want a multi-display environment or to check images on an iPad. Touch panel operation on Windows is also possible. I bought it for multi-monitor use, but I ended up buying another PC monitor, so it's in good condition, having only been connected once for confirmation. Luna Display automatically connects devices via Wi-Fi network or USB cable. For detailed system requirements for use, please check the manufacturer's website.
