[solved] Upgrade screen to FHD results to garbled screen

[gelomon]

Are you sure you're not using the kext patch for eliminating the glitch?
Also keep in mind that if you're using IntelGraphicsFixup.kext, it will apply that patch.

Oopps I might have described the effect wrong. Boot glitch(slight garble on boot) was gone but boot glitch fix is still in tact in my kext to patch. What I mean is there is no flick of garbled screen showing while booting

I did the suggested steps... extracted my EDID with EDID Manager, patched it with FixEDID, and the 21st bit was already 95, but Clover isn't injecting the new EDID for some reason. It still displays the original EDID in IOReg.

Probably Graphics/EDID settings have no effect without Graphics/Inject/Intel=true.

Can you provide a video of what you mean? Because I don't really understand what you're trying to say.

Here is the video hope it is can be posted:

The difference on the config on these videos are just the custom EDID.
boot glitch patch is still in kexttopatch
