Review on Astropad Display Extender Wireless Portable Compatible 12.3", 5120X2880P, 60Hz, by Zach Amin

I'm using it with an M1 laptop as my main computer and a late 2014 iMac as my monitor. It *looks* great, and I'm impressed they pulled it off - I'm glad to be able to use the beautiful iMac 5k as a monitor, even though the computer itself is no longer my primary device. noticeable delay. Not so much that it's unusable, but enough that it's a minor annoyance. It uses a wireless connection by default, but supports wired connections in some cases, which I think will help reduce lag. But it requires Thunderbolt 3, and my iMac only supports Thunderbolt 2, so that's not an option in my case (Luna Support, if you're listening, please let me know if I'm wrong!) Luna is clear about this only this will work for specific combinations of computers and devices, so check compatibility before purchasing. But if your stuff is compatible, it's a useful, if imperfect, device.
