I am using open source https://www.analogway.com/americas/products/software-tools/aw-edid-editor/

But there is almost nothing to edit. Two patches made by Clover is more than enough.

There's source code?

I think it requires registration. They speak about open source but no link to sources.

Thanks @jalavoui for revival of this app, after minor editing in source code I built it for Mojave/Catalina. Unfortunately DisplayMergeNub.kext doesn't load. I guess there's no cure for my DELL U2913WM. Trying to force RGB on HDMI(EDID edited with AV EDID Editor, f*ing YPbPr), nothing works even placing DisplayProductID-408a to /S*/L*/Displays/Contents/Resources/Overrides, also tried different scrips, nada.

i have it working but loaded inside a kext. check nootered/blue or if you wanna load it inside whatevergreen just add this 2 files and edit info.plist session for your display using hackintool

ofc you will need xcode to rebuild the whatevergreen.kext

 

here's the changes in latest sources

 

WhateverGreen.kext.zipWhateverGreen-master.zip

 

here's  sample of my display i can change using hackintool and then just copy the values to the info.plist inside whatevergreen.kext

 

detail is if you need to change settings you must unload whatevergreen cause if not hakintool will give a new vendor/product id

Still can’t get  RGB on HDMI, but this might be Hackintool thing(wrong EDID). Revamped Whatevergreen now injects given EDID(compared original with the one from IORegister),  it seems to be doing "DisplayMergeNub.kext's work" .  I’m going to check later with AW EDID Editor possible way of forcing RGB. BIG THANKS @jalavoui for your effort!

This is how I edited WhateverGreen-master/WhateverGreen/Info.plist

Spoiler

 

 

EDIT: No luck, IOReg shows injected (edited with AW EDID Editor) EDID, no RGB.

 

EDIT: Dell monitors connected to Mac via HDMI seems to only speak YPbPR wit each other, many threads on MacRumors Forum (some 30 pages), I'm afraid simple editing EDID might not be enough to resolve my problem.
