De enige aansluitingen die 4k 60 Hz doen is Displayport 1.2 en hoger en HDMI 2.0.
Wikipedia: Graphics display resolution
"Both HDMI 1.4 and DisplayPort 1.2 support 4K, at up to 30 Hz using a single cable.[56][57] DisplayPort 1.2 can also achieve 60 Hz at this resolution with a single cable, however early monitors achieve this with a tiled approach where the graphics adapter multiplexes two signals via Multi-Stream Transport (MST). The two signals (tiles) are reconstructed as a single image on the monitor.[58] Newer monitors such as the Asus PB287Q do not rely on tiling or MST to achieve 60 Hz.[59] HDMI 1.4 has no such option but HDMI 2.0 can also achieve 60 Hz.[60]"
Een Dual-link DVI-aansluiting kan zeker geen 3840 x 2160 op 60 Hz aan.
Een Single-link DVI kan namelijk, met reduced blanking 1920 x 1200 aan op 60 Hz.
3840 x 2160 is 3,6x zoveel, dus gaat nooit werken op een dual-link op 60 Hz.

In single-link mode, the maximum pixel clock frequency is 165 MHz that supports a maximum resolution of 2.75 megapixels (including blanking interval) at 60 Hz refresh. For practical purposes, this allows a maximum 16:10 screen resolution of 1920 × 1200 at 60 Hz (1915 × 1436 at a 4:3 ratio).[citation needed]
"To support higher-resolution display devices, the DVI specification contains a provision for dual link. Dual-link DVI doubles the number of TMDS pairs, effectively doubling the video bandwidth. As a result, higher resolutions up to 2560 × 1600 are supported at 60 Hz."
