What it does and who it serves
The Jansicotek DisplayPort 1.4 splitter switch takes a single DP 1.4 input and drives two displays simultaneously via one DisplayPort 1.4 and one HDMI 2.1 output. It supports 8K at 30 Hz, 4K at 120 Hz and 1440p at up to 165 Hz on the DisplayPort side. The HDMI output tops out at 1440p 144 Hz. It is aimed at users who need mirrored or extended desktops across two monitors without swapping cables.
Installation and common pitfalls
The unit requires the included USB 5 V power cable; it will not operate from the DisplayPort signal alone. Connect the source, attach both displays, then plug the power lead into any standard USB port. A frequent issue is forgetting the external power, which results in no signal or unstable output. Ensure both cables and monitors support the target resolution and refresh rate, as the switch passes through the native signal without scaling.
Behaviour under sustained load
The switch handles a continuous 32.4 Gbps bandwidth stream, maintaining stable 8K 30 Hz or 4K 120 Hz output during extended sessions. It supports both SST mirror and MST extended modes without dropping frames when the host GPU and cables meet the required specifications. HDR metadata passes through unchanged. No active cooling is present, so the aluminium casing dissipates heat passively during prolonged operation.

Questions about this item
How can I confirm the 8K@30Hz output is active on both the DisplayPort and HDMI 2.1 ports after connecting the DC 5V power line?
Connect the power line, attach monitors to both outputs, then check your OS display settings to verify each screen reports 8K at 30 Hz and that MST extended mode shows two independent desktops.
Which cables and monitors must I supply besides the included switcher, power line and instructions?
You need a DisplayPort 1.4 cable for the host input, plus one DisplayPort 1.4 cable and one HDMI 2.1 cable for the two outputs, along with monitors that support the desired resolution and refresh rate.
When should I choose the MST extended mode versus the SST mirror mode for my dual-monitor setup?
Select MST extended mode when you want independent desktops across both screens at up to 8K@30Hz or 4K@120Hz; choose SST mirror mode when both displays must show identical content.
