Full Resolution at Clover


Best Answer Dr. Hurt, 18 August 2014 - 11:21 AM

Add this to your config.plist
<key>CustomEDID</key>
<data>AP///////wAEcsoComAwIAMWAQOAPCJ4yntFpFVKoicLUFS/74BxT4FAgYCBwIEAlQCzANHAAjqAGHE4LUBYLEUAVlAhAAAeAAAA/QA4TB9TEQAKICAgICAgAAAA/ABTMjcxSEwKICAgICAgAAAA/wBMVVcwRDAwNTg1MzAKAOg=</data>

And keep PatchVBios enabled but remove the ScreenResolution entry from the config.plist

Like it was suggested before, try to add your monitor’s EDID (extracted from windows) in CustomEDID and enable InjectEDID too. Post a boot.log and config if it still fails. Beware though that there currently isn’t a definitive solution for this problem, it might just not work with your graphics/monitor. You can try as a workaround to boot in legacy mode, which uses a different method and sometimes succeeds where UEFI fails.

does anyone know if a custom EDID is a solution to the resolution issue on virtualbox?  I have ML, Yosemite, EC all running flawlessly with clover on vbox except for the resolution issue.  My limited understanding is that in EFI mode on vbox you can choose different GPO modes.  Mode 4 is 1440x900 and Mode 5 is 1920x1200.  Is there a way to inject a custom EDID using clover to bypass/expand this so I can run fullscreen 1920x1080?  Sorry for my limited understanding of EFI, GPO, and how OSX gets its possible resolutions.

Time to resurrect an old topic!

 

I am at my wits end. I got a new monitor (Dell U2715H) and graphics card (Nvidia GT 710) and now my Clover boot screen is stretched. It was perfect before. I was hoping to get the boot screen to be at the monitor's native resolution (2560x1440) but at this point I'd be happy to just get non scaled icons at boot! Once booted I get full native resolution so this is just a semi cosmetic thing but it drives me crazy.

 

I have done a dozen things to get it to work. I extracted EDID while booted into Windows and added that in the Custom EDID section. Checked and uncheck every combination of LoadVBios, PatchVBios, Inject EDID. Removed Screen Resolution and changed it to several options. Nothing works. I always get 1280x1024 (in Clover's information menu) and stretched icons.

 

Can anyone shed some light on this? The "Best Answer" above does not work for me.

 

Thanks!

I have been playing around with this issue for weeks and I have no solution. I have tried the solution in this forum but that did not work. I can't for the life of me figure out why I can't get full resolution at clover boot screen. I have tried a dozen different combinations of EDID, VBios, putting video cards ROM in EFI folder, etc. but nothing works. I also always get the "Graphics Output (UEFI) 1280x1024" message in Clover's info screen.

 
CsmVideoDxe-64 is used only for UEFI motherboards and I can see that you have a legacy board as I do.
 
Everything worked fine before I upgraded my video card and monitor (EVGA Nvidia Geforce GFX 750 TI SC and Dell 2715H).
 
I really hope SOMEONE out there has a solution.

I tried one more thing as a last try.

 

1) Screen Resolution set to 2560x1440

2) Load VBios (placed VBios file for card with name 10DE_1380.rom in EFI>CLOVER>ROM. Downloaded correct ROM from techpowerup)

3) Patch VBios

4) Inject EDID (let clover inject)

 

Still no correct boot resolution but this is what I get in the boot log now:

Gouldn't find proper solution to make my Palit gf650ti Boost bootscreen with 1920x1080. Does anybody could lead me or link to where and how modify bios strings that will unlock 1920x1080?

Native 1920x1080 (and above) resolution is only possible with UEFI GOP compliant GPUs.

That's not true. Before I had my 750Ti and Dell monitor I was able to achieve a 1920x1080 resolution at boot. And if you check my signature you will see I do not have a UEFI mobo.
