Question: is dvi capable of 4k?
Answer: DVI. ... A dual-link DVI connection (as opposed to single-link) can handle 2560x1440 at 60Hz, but not 3840x2160 (which is the typical; 4K resolution). This means that unless you have two dual-link DVI outputs and your monitor can accept two inputs (few can), you cannot drive a 4K screen at 60Hz using DVI.
