I can’t find a 5k 27” screen for less than $900, unless it is used. All the cheaper displays are 4k rather than 5k.
I saw that some people were ripping apart their old iMacs and installing new hardware boards to turn them into an external screen, just because of the crazy costs for 5k displays.
I converted my old 2015 iMac 5K into a working external monitor using a converter board. Here is exactly how I did it and what it cost.

I will probably have to eat the high costs for a 5k display once the m3 studio computers are released. Right now it’s $2000 for apple’s display with height and tilt, about as much as I paid for the while iMac in 2018.
