In Clover your are booting in VESA mode which 1920x1080 is perfectly normal for that. Once the drivers kick in your are running your native resolution which is normal. You can try setting the Clover to 2560x1080 but it will only work if your card has a VESA mode at that resolution.

Thanks Slim Jim for your response. You helped me to understand what is happening to my display. I will research to see if my card has VESA mode at 2560x1080, which I don't think so because I tried to set it there in clover earlier as I stated above and it doesn't make a difference.
