Question about Astro HQ LLC Luna Display Astropad USB-C

Yes, the "Luna Display Astropad USB-C" device can be used to use an old iMac (in this case an iMac 2017) as a second display for a new iMac M4 or another compatible Mac model.

Here are the key steps and details:
- The Luna Display USB-C Adapter supports Macs with USB-C ports, which applies to the newer Mac models, including the iMac M4.
- You need to connect the Luna Display Adapter to the USB-C port of the new iMac (or Mac Mini) and install the appropriate software on both devices.
- It is possible to connect via WiFi, Ethernet or now also via a USB cable, which can improve performance.

This makes it possible to use the old iMac as a second screen and access its integrated components at the same time.

Is it possible to connect a Lenovo Thinkpad from the shop to the new iMac 2024 as a monitor?
So the iMac should be the new main monitor because I have a Lenovo laptop from the shop. I would like to connect this to the iMac. Is that possible with Luna Display?
