Dual-display DP 1.4 switch

This Jansicotek switch takes one DisplayPort 1.4 input and drives both a DisplayPort 1.4 and an HDMI 2.1 monitor simultaneously. It supports SST mirror and MST extended modes so two screens show independent or cloned content without manual switching. The unit requires the included 5 V USB power cable to operate. It suits desktop users who need a second display from a single GPU port.

Replaces basic single-output adapters

Unlike simple one-to-one converters this device adds a second active output and MST extended desktop support. The upgrade is worth it when your graphics card has only one DisplayPort but you want both a high-refresh DisplayPort monitor and an HDMI 2.1 screen connected at the same time. It also maintains backward compatibility with DisplayPort 1.3, 1.2 and 1.0 sources.

Sustained 8K 30 Hz and 4K 120 Hz output

The 32.4 Gbps bandwidth handles 8K at 30 Hz or 4K at 120 Hz continuously on the DisplayPort output, while the HDMI port delivers 4K at 120 Hz and 1440p at up to 144 Hz. HDR and 4:4:4 chroma pass through without compression during long sessions. High refresh rates above 144 Hz at 1440p are limited to the DisplayPort output only.

Questions about this item

What power connection does the Jansicotek DP 1.4 switch require to operate?

It needs the included DC 5 V USB power cable plugged in; the unit will not function without external power.

Which cable should I connect first when setting up the switch for dual-monitor extended mode?

Connect the DisplayPort 1.4 source cable to the single input, then attach both the DisplayPort 1.4 and HDMI 2.1 monitor cables to the two outputs before applying power.

Will the HDMI 2.1 output still deliver 1440p at 165 Hz or 144 Hz after extended use?

No, the HDMI port is limited to 1440p at 120 Hz; only the DisplayPort 1.4 output supports 165 Hz or 144 Hz at that resolution.
