Clover bootloader screen resolution

[iadmir]

old thread I know.

I stumble across it and though I'd put some info here.

Seem to have solved it.

windows 8 whql
disable csm
no clover driver CmsVideoDxe-64
did apply nvram in clover configurtaor (unsure if this is important or not)
Typed in my res in clover configurator 1920x1200
no load vbios or edid in clover configurator
Started working once I did "disable fullscreen logo show" in the bios.

Thanks it works for me!
in fact, only the first two steps were enough for me..

I can't get to reach 4k resolution with an RX 580 (Monitor connected via Displayport)
Gigabyte Z390 Aorus Pro

Clover: 5103
Theme: Catalina 4k
CSM: Disabled
Boot: Win 8 / 10 WHQL
CC -> GUI -> Resolution: 3840 x 2160

I also tried switching to the second Displayport of the GPU. No changes.

Old post but give my experience,
In Clover Config > GUI > Screen Resolution
- Insert your screen resolution
- Reboot to your UEFI BIOS
- Disable CSM and save
- Reboot and you will see that Clover Bootloader resolution is more nicer

Can confirm that just disabling CSM & setting resolution in Clover Configurator should work.

CmsVideoDxe-64 works but during the progress bar the whole screen goes black for about 2 seconds then comes back and take me to the login screen, I know it acts like it changing the resolution. I prefer to have the progress bar go all the way through. Funny thing is for years when I was using the GTX570 it was distorted and changed resolution halfway through the progress bar using Sierra. When I installed the AMD RX570, I get the correct resolution on the Clover boot but could never get the card to work right in Sierra. I updated to Catalina and now the card works in Catalina but not in Clover boot, I had to use CmsVideoDxe-64. I couldn't find CSM in my BIOS. But why does the Clover work in Sierra but not Catalina using the RX580?

For my Gaming 7 motherboard, Nvidia graphics card, and Dell 5K monitor, I finally got around to actually following the instructions in this thread by setting these options:
- Windows 8/10 Features: Windows 8/10 WHQL
- CSM Support: Disabled (this doesn't appear unless Windows 8/10 Features is set to one of the Windows options instead of Other OS)
Now my Dell monitor connected to Nvidia using mDP boots into Clover at 4K instead of 1600x1200. The Intel Graphics always booted this monitor into 4K.

It doesn't affect the BIOS screens (version F20), and it doesn't affect the EFI Shell (max console lines is still 60).
It affects Clover and Mac OS verbose and non-verbose boot. I think it affects the Clover debug text for kernel patches, etc. (after you choose to boot a Mac OS).

For the Apple 30" Cinema Display connected to either Intel Graphics or the Nvidia, it still booted into 1280x800 instead of 2560x1600. So in this case another solution is required (maybe the EDID override protocol idea).

The Dell in 5K mode (dual DP) still boots at 1600x1200 into Clover and Mac OS verbose and non-verbose boot. The system crashes as usual when MacOS completes booting (I'm still using El Capitan, haven't tried Sierra). 5K works when it's not connected at startup.

Strange thing happened to me today. I haven't been using my hackintosh for a long while. I booted up into Clover and found that my Dell UP2715K was showing 5120x2880 60Hz! I took a screenshot in Clover to confirm (also Clover Info menu and debug log showed 5120x2880 mode). I didn't think dual cable displays could work at full resolution.

GA-Z170X-Gaming 7​

BIOS Version: F22i​

Windows 8/10 Features: Window 8/10 WHQL​

CSM Support: Disabled​

Initial Display Output: IGFX (but it's not connected to a display)​

Dell UP2715K port 1 and port 2 connected to port 1 and port 2 of Maxwell Titan X​

Clover 4910​

Clover 5102 (but macOS hangs during boot - I need to fix it to match 4910?).​

Once booting into macOS completes, it switches to 2560x1440 mode. I need to switch off the display, wait a couple seconds, then turn it on to get 5120x2880 again.

Thanx. Problem solved.

In BIOS Boot Option:
⦒Legacy boot
⦒UEFI boot (with CSM)
⦒UEFI boot (without CSM) ← I choose this option & the boot regulation is fixed.

Asus Z390 Gaming Plus WiFi, intel hd630, two 4k displays (HDMI and DP). CSM disabled, tried "windows" and "other os". None of the technics work. Clover still can't found any resolution above 1280x1024.
