You sure it’ll handle 2 x 4k monitors ? Most say it’s for gaming . I’m looking for none gaming video card. I purchased nvidia quadro p400, it’ll handle 3x 4k monitors.
I do not know about exact model but for example mine Radeon 6950 which soon will be like 10 years old supports like 2 DVI and 4 display port. It costs peanuts now and you don't need more, if needed - https://www.techpowerup.com/forums/...-for-6-x-high-res-monitors-not-gaming.236686/
