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.
