Could, please, anybody with knowledge help me?
Problem: on internal monitor all colors are perfect. on External - I have banding gradients and colors.
Intel® HM76 Chipset
External monitor 21:9 2560x1080 via HDMI.
What I tried:
1. Different versions of Lilu and WhateverGreen
2. Different combinations in config.plist in devices
In mac Graphics/Displays I see only 24bit of color depth. Is it OK?
I don't update WhateverGreen, because then my external monitor stops working at all
What other info should I provide?
How to fix it? Thank you in advance

could you help me with Intel UHD 620 HDMI port?
HP ProBook G6 440
Intel Core i5-8265u
I've installed Catalina 10.15.4
But I can't get HDMI working
When I connect HDMI cable I got freezes and errors as in file freezes.png (attached)
[IGFB][INFO ] Setting DP power failed (0xe00002bc), ignoring empty dongle handling (likely HDMI/TMDS case)
I also looked into IOregistryExplorer and see that the connect type is 00400000 there for FB@1
I tried to patch it via setup.plist but it seems that there is no change in IOregistryExplorer.
Though the Hackintool sees the change (image attached)
Im having similar issue with my HS setup, dell latitute 3480, i5-7200U
Once the hdmi plugged in, the laptop display went blank, only could see the external tv
But, when i put my laptop to sleep & wake up again, both screen got display (hdmi still connected)
Even the hdmi could be plugged off & in (after sleep), the laptop display is fine
What could be the culprit?
