I have followed the following guides for help and troubleshooting.
Display can't be driven at native resolution (> 1080p)

I have the latest Nvidia Web Drivers installed and running, but I don't have an option to display in 4k resolution.I can output normally to a 1080p monitor and can output 1080p on my 4k TV, but it has large bars around the edge of the screen. I have tried HDMI->HDMI cable as well as DisplayPort->HDMI with the same results. Either cable works to output 4k to Windows or my MacBook Pro.

I am running 10.13.6 (17G12034) with Nvidia Web Driver version 387.10.10.10.40.135. I've installed kexts for both Lilu and WhateverGreen and I've installed the Pixel Clock Patch (v4) as recommended (status shown below). I've also tried SwitchResX and ResXtreme, but without success - higher resolutions are not listed.

SIP looks to be disabled, all good!

Unknown version of CoreDisplay found.

I am attaching my config.plist, but I've run out of ideas and references to try to get this working. Is there something I've missed?

injecting Intel graphics is wrong:
Code:
<key>Graphics</key>
    <dict>
        <key>Inject</key>
        <dict>
            <key>ATI</key>
            <false/>
            <key>Intel</key>
            <true/>
            <key>NVidia</key>
            <false/>
        </dict>
should be set to false

also:
Code:
<key>IntelGFX</key>
            <string>0x12345678</string>

should be:
Code:
<key>IntelGFX</key>
            <string>0x0</string>

not sure if you need this:
Code:
<dict>
                <key>Comment</key>
                <string>framebuffer4K</string>
                <key>Disabled</key>
                <false/>
                <key>Find</key>
                <data>AwAiDQADAwMAAAACAAAwAQ==</data>
                <key>InfoPlistPatch</key>
                <false/>
                <key>Name</key>
                <string>AppleIntelFramebufferAzul</string>
                <key>Replace</key>
                <data>AwAiDQADAwMAAAAEAAAAAw==</data>
            </dict>

you may also try adding:
Code:
-cdfon
to boot arguments

I had to look up what cdfon flag does. I made these changes and I'm still booting up without any issues, but there doesn't appear to be any change in my resolution options. I'm attaching my updated config.plist.

I removed cdfon again, but no apparent changes. It may be worth mentioning I have a couple of other kexts installed as well.

Installed under 10.13:
  • AppleALC
  • HDAEnabler1
  • Lilu
  • WhateverGreen
Installed under Other:
  • FakeSMC

you need to keep all your kexts in clover/kexts/other (HDAEnabler1 shouldn't be needed)
 
I moved all of my kexts into Other, but still no change in available resolution choices.

I'm looking at my boot log and it appears to be setting screen resolution to 1280x1024. Although, my resolution is 1920x1080 once booted. Could this be part of my problem or is this normal? Full boot log is attached.

Is it possible that MacOS doesn't recognize what resolutions are compatible with my display?

Here is what my Displays section looks like in Hackintool. I have my 43" 4k TV and a 27" 1080p monitor (for comparison). My 4k display doesn't have a Product ID or Serial No.

Screen Shot 2020-05-22 at 12.31.42 PM.png


I'm able to use ResXtreme to force my 4k display to output as a maximum of 2560x1600, but no higher resolution is listed. Oddly, my 27" monitor shows resolutions all the way up to 5120x2880 in ResXtreme.
 
Whoa, I've got 4k resolution.

So, I had to use ResXtreme to force the highest resolution it recognized (2560x1600).

Then, I was able to use Settings > Displays to enable Overscan for my display (which normally results in a black screen). After enabling Overscan, my black borders were gone (image went all the way to the edges of the display).

Finally, I ⌥-clicked Resolution: Scaled and there was a choice for 3840x2160, which actually works!

Thanks for your help @Feartech and @jaymonkey. Greatly appreciated. Cheers.
