new board for iMac 5k DIY conversion?

Hi all,

I stumbled across a 'new' display driver board. I'm aware of the R1811, R9A18 and U49 boards (details here: https://khronokernel.com/macos/2022/03/01/5K-MONITOR.html)

Now there appears to be a new board: RY-W9CUHD-AA1 (https://stonetaskin.com/products/stonetaskin-jry-w9cuhd-aa1-5k-driver-board-for-imac-27-inches-a1219-a2115-lm270qq1-qq2-diy-external-monitor-display-screen-dp1-5?variant=43939337797786)

Anybody using this? Good/bad?

​

Cheers
