I wanted a 5K screen, but they're very expensive. Then I saw a late 2015 iMac with a gorgeous 5K screen (it's like reading from paper) at a local market place for €250. I planned to do the hardware mod and never got around to it. So I wondered whether, with the help of Opus, I could do it in software instead. After about two months of tinkering, testing, fixing and designing, it works! You get a native, sharp 5K picture, driven by your newer Mac. Better than throwing the iMac away, if you ask me.
You just need one cable between the two Macs: USB-C to USB-A, or a Thunderbolt cable (USB-C to USB-C) on iMacs from 2017. The iMac shows the Mac's screen at its full resolution: 5K on the 27-inch models from late 2015 to 2020, 4K on the 21.5-inch Retina ones. It isn't a video stream, and the picture is lossless when the screen is still, so text stays exact. It plays sound through the iMac and works with the laptop lid closed. It's basically a beautiful 5K monitor at a bargain price!
It's $39 after a 7 day trial that needs no account or anything, you can see if it works for you first:). There are free alternatives, and I list them with links, including where they're the better choice: https://secondglow.app/guides/5k-imac-as-monitor
