3.2 Gen 1 is only 10GB/s, which at best can transfer about 1GB/s.
I have used HDMI on both the TV in the garage to ensure the system is working and on the 65 inch 120MHz Samsung in my condo. They both work without a problem.
What graphics card are you using?I use a Samsung 43QN90B, through HDMI. I cannot get the 4k@144hz that my TV is capable of, but 4k@60hz with HDR works normally (macOS 12.5).
what graphics card are you using?
One thing I haven't tried is resetting NVRAM also I updated to 12.5 using software update. It worked fine. and again on my old 22 inch IPS monitor everything was working fine. (the IPS monitor is connected via HDMI with a HDMI to DVI converter dongle.
Sapphire Nitro+ 6800 XT with EK Quantum waterblock. OverClocked from 2250 to 2650MHz, UnderVolted from 1150mv to 990mv, maximum power draw of 323 watts.
Nice card!
Did you have to patch the sapphire nitro+ at all to get it to work?
I had to patch my Power Color 6900 XT to get hardware acceleration/metal to work but it was easy. I can’t imagine that the card is somehow overheating after a few seconds of OS X, because it works perfectly with my OLED TV in Windows 11. It even works with the USB-C dongle in Windows 11. I’m going to go try resetting NV ram now and using a Thunderbolt to HDMI dongle
’m going to go try resetting NV ram now and using a Thunderbolt to HDMI dongle
So I ended up ordering the wrong kind of thunderbolt to HDMI dongle.. I needed a female HDMI dongle and accidentally ordered a male. since my OLED is already hanging on the wall, reaching a free HDMI port to plug in the male HDMI cable is kind of a pain...
BUT...
Last week, when I was looking to troubleshoot thunderbolt issues I ordered an ACASIS USB-C NVME enclosure hub that includes ethernet and HDMI by accident thinking it was the thunderbolt enclosure.
since I didn't have a thunderbolt to HDMI dongle I could use right now, on a whim I said.. let me try the HDMI port of the ACASIS USB-C hub. it would give me a chance to test the ethernet port on the hub as well.
I was apprehensive, especially since some of you had mentioned that using display port and piping it through the Thunderbolt port is not ideal... BUT...
wouldn't you know it..? it works!
the display defaults to 1920 x 1080.. but I can push it all the way to 3840 x 2160 without issue. (incidentally, 3840 x2160 is the "recommended" resolution under windows 11 as well, but I can push it all the way to 4096 x 2160 in windows without issue with or without any USB-C Hub.
I'm sitting about 8 from away from the screen and ironically 1920 x 1080 is the most comfortable resolution.
youtube videos in chrome run at 2160 and look amazing.
as I type this, the dreaded "screen darkening" thing that LG OLEDs like to do just happened to me. but it's late here and i'm using night mode so it wasn't too jarring when everything suddenly brightened up.
one last data point..
sitting between my hackintosh and my OLED is this HDMI scaler/splitter thing that was originally meant to send the audio fm my Apple TV 4K to my 12 year old AVR that freaks out when it sees a 4K video signal (the splitter spoofs a fake 1080p video signal to the AVR so that it will accept the audio signal, and then the 4K video signal is sent separately to the LG OLED. I have a SH_ARC device so that I can play the audio from my SMART TV apps from the OLED on my old school AVR, so I don't actually need the splitter, but everything seems more stable with the splitter in place. unfortunately this splitter maxes out at 60 Hz, so I cannot attempt a 120 Hz video signal which is my ultimate goal.
tomorrow I will remove the splitter and plug the HDMI cable from the OLED directly into the ACASIS USB-C hub, but I think the hub maxes out at 60 Hz as well, so it won't make a difference.
Hi, first thanks to all those for their hard work on this. I am hoping someone can help me. I was able to install Monterrey 12.5 and it get it up and running. iCloud, WiFi Calling and iMessage all work, I have yet to be able to get unlocking with Apple Watch to work and haven't tried some of the others. My biggest problem is I can't keep the machine running for more than 5-10 minutes before it randomly reboots. My EFI and latest log are included. Bios settings are set as per the initial post on the most recent bios update. One thing to note, under boot->Secure Boot->OS Type I have to select "Other OS" or I get an error from the bios when trying to boot that says "Invalid signature detected. Check Secure boot policy in setup." with Windows UEFI selected. Any help the community can give is greatly appreciated!

Funny enough I used your 0.8.2 EFI here as a starting point and then updated to 0.8.3 and added the gpu temp monitoring kexts.Did your make the EFI yourself from scratch or use a pre-made one?
Other OS is what I use also to avoid the Invalid Signature.

Enjoy your cruise and stop responding In the meantime I will try disabling any non-required kexts and then re-enable one by one to see if I can figure out anything. Thanks for the insight.My pre release of 0.8.3 was working when I left for my trip and will not be back for another 2 weeks or so to do the final release.
I don’t know if any breaking changes have happened in Monterey since the pre release of 0.8.3 was made. I have not booted into Monterey for more than a minute to test the EFI since a few days after the initial Ventura beta came out. So it could be the EFI’s Monterey compatibility.
First thing to try is disabling the GPU kext. If it is not from the original EFI.
The simplest thing to do is to downgrade 0.8.2 EFI to determine if it is a Monterey compatibility issue. It still includes the EXT4 but not file BRTFS for Linux. The only changes to 0.8.3 that would be relevant to Monterey is native OpenCore file support for EXT4. But this is already covered in the 0.8.2 release.
At this time the Internet on the cruise ship is so bad I am unable to open the log. Hopefully it will improve shortly so I can take a look.
Unless you have the skill set to write the drivers required for USB-C display to work, which Apple’s own engineers have been unable to get to work consistently you will more than likely be persistently plagued by problems.
