HDMI output stream corrupted on macOS 11

@Alex-Zhangzhipeng That’s #52

[VisualEhrmanntraut]

I meant with the latest kext. And, one of the people here said that it is resolved by updating to Monterey. This is at lowest priority right now as it's a rare issue and specific to BS (Catalina untested)

Can you share me your EFI folder?
I'm stuck on a black screen after boot

@Hachi-R >HDMI
Yeah uh I don’t think I’ve ever seen a system that uses HDMI for the primary display and doesn’t have a corrupt display stream

[womengzouzailushang]

是的，我也是5600G，HDMI输出，屏幕紫色绿色，

[womengzouzailushang]

我5600G HDMI输出也是这样故障（我主板没有DP接口）；我还有个朋友5600G DP输出是黑屏状态

[felicia-wen]

HDMI as primary display works fine here, DP as primary results in no signal

[womengzouzailushang]

系统请升级到Monterey，更新使用原生支持Monterey版本的NootedRed驱动就可以正常显示了，我5600G，HDMI输出紫屏绿屏是这样解决的

after i do all steps to use nootedred kext, i got iGPU acceleration, but my screen glitchs

my cpu is: Ryzen 5 5600g my iGPU is: Radeon Vega 7 i use a HDMI monitor

Can You give me the EFI file you are using? I am also using 5600G. But I can't find the EFI. Please give me your EFI

[VisualEhrmanntraut]

@Sayor0630 No.

[Sayor0630]

@Sayor0630 No.

But I can't understand what to do. How to use this Nootedred. Where is the actual file? And where should I put what?

Two words. Github Actions

Is this issue still relevant?

[maff1989]

I had a similar issue using a 1440p monitor. The screen would occasionally flicker and go black, then come back on, then repeat. Sometimes it would work properly but it was hit or miss. My 1080p monitor(s) worked fine. I haven't tried with the latest kext from yesterday, I'll report back once I'm able to test again.

BTW I'm running:
AMD Ryzen 7 5825U with Radeon Graphics
Family: 19h, Model: 05h

[maff1989]

To provide my report, I'm using the latest kext and had my dual 1440p displayport monitors plugged into my Lenovo USB-C docking station, which was routed via USB-C cable into my laptop. Only 1 monitor was detected by macOS, and kept disconnecting and reconnecting without me touching the cables. Unfortunately don't have any additional information to provide besides that, but it seems the issue isn't just related to BigSur as I'm running 13.5.1. Happy to run more tests to provide logs, just not sure where exactly to find those logs.

[VisualEhrmanntraut]

Your issue is different to the OC; this issue was the screen being corrupted, not constantly connecting and disconnecting. Are you sure your cables aren't bad? And, which SMBIOS are you using

[b00t0x]

@maff1989 macOS does not support MST, you can only use mirroring even if you connect two displays to the dock.
It's the same on Mac, so I don't think it's a problem of NootedRed or Hackintosh.

[VisualEhrmanntraut]

Guess it's not relevant anymore.
