Haven't you tried out the DisplayID block at the top of the Extension block instead?

It doesn't make sense for 36-bit to work but not 30-bit. You might have to enable YCbCr 4:4:4 deep color as well; otherwise, it might only be available with RGB. If that doesn't work, it might be a driver bug. I don't have a deep color monitor to test this. Also, the HDMI specification says if it supports any deep color mode, it shall support 36-bit mode, so maybe you have to leave that enabled.

Thanks, so you can't confirm that it works. Deep Color is supported and enabled in B8, once again:
- if 36 bits is checked: 8 bit and 12 bit
- if 36 bits is not checked: only 8 bit

Initially when gaming in 1920x1080 or 1600x900 resolution, the TV or laptop seems to upscale and output to the native res of 4k as displayed when I hit the info button on the TV. The problem is my graphics card can only do up to 30hz at 4k, so as long as it is outputting in 4k I can't get 1080p 60hz even if that is what I have the game set to. I have solved this problem in 95% of games with CRU by deleting or lowering priority of 3840x2160 under detailed resolutions and moving 1080 to the top. This causes the image to be output at 1080p 60hz and the TV properly shows this in the info. Some rare games still give me odd issues, like I can run at 1600x900 60hz but if I set the game to 1080 it will resort to outputting 4k 30hz again. I'm hoping to better understand why this happens.

2nd issue is, sometimes I will lose audio over HDMI. I hit restart.exe, then the HDMI audio device will completely disappear from playback devices and I'm left with only "Speakers". If I unplug/replug HDMI cable to restore default TV settings the HDMI audio device will return. I have tried importing the hdmi-audio.dat extension block but I seem to be missing something there. It seems like if I simply deprioritize 3840x2160 instead of outright deleting it I can get 60hz without losing HDMI audio. But I'm not entirely sure if that is what's solving it.
The audio issue might be a driver bug. To troubleshoot both issues, I would try just the bare minimum configuration that does what you want.

Try importing this file and do NOT check the "Import complete EDID" option:

That includes 1920x1080 @ 60 Hz, 3840x2160 @ 30 Hz, and HDMI audio.

I'm back...had it working for a while. Ended up having to reset the settings, however now no matter what I do I lose HDMI audio. Initially all I did was move priority of 1080 to the top, save settings, restart driver, and was able to retain HDMI audio. Now nothing is working. It seems making ANY changes, saving, and restarting the driver results in lost audio until I re-plug cable or reset settings again.

Tried importing the bin to add the HDMI extension - no luck.

More details regarding my issue. Something very odd is going on.

I do believe it has to do with drivers. Given that it's a laptop it has dual video cards, Intel HD Graphics and a Geforce 950m for gaming. The HDMI/display info and such goes through the Intel. I have found that after restarting the driver and losing HDMI audio, if I go to device manager > Sound, video and game controllers > Intel® Display Audio, and I click Update Driver > Browse my computer > Let me pick from list, install the standard "High Definition Audio Device" instead, the device shows back up in Sound as generic Digital Audio (HDMI) and I get sound again. Ok, cool. Click restart64.exe...still there. Cool. Click restart64.exe again to double check...and it's gone again. Ok, so I go back to Sound, video and game controllers, reinstall the old Intel® Display Audio driver. Audio pops back up as 49S405 (HDMI)...sometimes. Hit restart64.exe, gone again. Reinstall generic "High Definition Audio Device", it comes back until I hit restart64.exe 1-2 more times. It seems to either only work for one restart once changing the Intel Audio drivers, or it is completely random before it disappears again. I have no idea what is going on.

Running restart64.exe basically does the same thing as disabling and enabling the display adapters in the Device Manager, so if doing that also affects the sound, then I can't really do anything about it. What about if you reboot instead of running restart64.exe?

Rebooting essentially sets everything back to TV defaults - no EDID overrides. If I start up a game it upscales to 4k 30hz, I get HDMI audio back, etc. Same if I unplug-replug the HDMI cable or turn the TV off then back on. After any of those actions, I need to hit the restart exe to have my CRU settings applied and set the primary detailed resolution to 1080, which is then when HDMI audio disappears. No need to go back into CRU, I just have to hit restart64.exe. Is this abnormal?

Yeah, that's not normal. I don't know what you can do since that seems like a driver bug. What laptop model is it, or what model Intel CPU does it have?

Aspire VN7-571G. Intel i5-5200U CPU. I'm wondering if updating the Intel GPU driver from the Intel site several months ago instead of sticking with the factory driver is a problem. I'm going to re-install the original driver from Acer's website in the meantime.

Any ideas at least why CRU settings aren't persisting every time my laptop loses signal to the TV? If I could figure out why I have to use the restart exe every time that may solve the issue, because I have found I can cycle the Intel® Audio driver and get it to show back up again. But it disappears the next time I use restart.

I recently got a Pioneer receiver VSX-LX503 and LG 65C9 OLED TV. When I connect the TV through the receiver Win 10 GTX 1050 Ti is reporting it as a DVI connection at 1080 res. If I connect the TV directly to the PC it reports HDMI 3840 res.

Would this CRU utility help in this situation?

It might, but that shouldn't be happening because that means the HDMI data block is missing. You can use CRU to manually add an HDMI data block (and HDMI 2.0 for 4K), which might work around the problem, but the real problem is the receiver is providing the wrong information for some reason.
