Weird scaling on clover bootloader

So my clover boot loader has some black bars all around the bootloader screen. It is 1080p resolution but for some reason its smaller than normal and centered. I use a gtx 670, i7-6700k and a asus maximus viii hero motherboard. Hackintosh works fine and stuff but the bootloader just kind of annoys me with some themes. My hackintosh is set to a 17.1 mac model so im not sure does this anyhow make changes to the bootloader. I currently use a acer 144hz 1080p 24 inch screen. Haven't tested yet changing settings from my display or doing some tweaks on my bios but i'll try later. Any help for this???
