UPDATE: Fixing 4K Monitor Resolution Issues
After
upgrading to 4K monitor, I noticed some issues with the resolution during startup. Both the Clover UI and Apple loading screen were low-res, and the Clover UI appeared stretched because it clearly had the wrong aspect ratio.
The first thing I did was set
CSM
to
Never
in the UEFI BIOS. This changed the Clover UI and Apple loading screen to the full 3840x2160 resolution, but everything was small because the resolution wasn't scaled.
Next, I used Clover Configurator to set
EFILoginHiDPI
and
UIScale
to
2
in my Clover config.plist. Setting both to
2
made the Apple loading screen 1920x1080 scaled/hidpi. Setting just one of them to
2
did nothing.
Unfortunately, the Clover UI still wasn't scaled, and I haven't found any tweaks to fix it. I read somewhere in the forums that using a Clover theme designed for 4K resolution would resolve the issue, so I might try that in the future. Right now, I'm still using the tonymacx86 theme.
