HDMI 4k@60hz + G-Sync Displayport on MacOs Catalina

[needsmacosdisplayport]

I have https://www.newegg.com/black-wavlink...1DN-0023-00014 with an Acer Predator XB321HK and XB271HU.

I have 2 different questions.

1. ~~HDMI 4k@60Hz not working on MacOs Catalina. For the 321HK I'm only able to get 4k@30Hz. Is there something I'm missing?~~ HDMI 1.4 only supports 4k@30 hz. So I really need Displayport to work
   
2. G-Sync Displayport for Macos support. Displayport is not working for either monitor. Looking on the forums and the latest Window release apparently Acer G-Sync displays are not Displayport compliant. What is the timeline on a macos release with the g-sync fix? Could someone send me maybe a development build for MacOS with the g-sync fix patched in?

I am attaching my lops from the support tool. I've checked that the extension is loaded and did the crsutil step I saw in another post.

This is my first time posting so please let me know if I'm missing anyhting.
