" rel="nofollow - I noticed that on my 21:9 2560x1080 LG monitor,  the UEFI/bios is in the poorly stretched 1024x768 resolution. It seems that the UEFI/ bios obviously doesn't support 21:9, and only supports 16:9 and 3:4 which is really sad.

Anyone seen the implementation of UEFI memtest86? When you run the test, it actually scales the test size pixel by pixel, so it shows as the actual 1024x768 on my 2560x1080 monitor which is really neat.

Will this ever come to ASRock? Or will ASRock implement a 21:9 support? Anyone knows if another brand already has this?
