There also exists "dual link" DVI port: DVI-D. Also: reading wikipedia page:

https://en.wikipedia.org/wiki/Digital_Visual_Interface

I see that single link DVI supports up to WQUXGA (3,840 × 2,400) @ 17 Hz
(164 MHz) whereas dual link DVI supports up to WQUXGA (3,840 × 2,400) @ 33
Hz with GTF blanking (2 × 159 MHz)
