I have monitor connected by DVI and a 4K tv connected by HDMI. I have a Gigabyte GeForce 1050 OC 2G video card. The firmware takes 15 seconds to load (systemd-analyze) so I tried the Ultra Fast Boot (UEFI) option in the BIOS. With Ultra Fast Boot the firmware loads in less than 5 seconds. All seems to work with just the DVI monitor plugged in. When I try to boot with the 4K tv attached, the monitor (DVI) screen is interlaced (it's not supposed to be). 1920x1200 59.95*+ I can changed to a lower resolution and is not interlaced.
