Bi-Directional DisplayPort 1.4 Switch

This DisplayPort 1.4 switch connects two sources to one display or one source to two displays in a bi-directional layout. It supports 8K at 30 Hz, 4K at 120 Hz and 1080p at 240 Hz with 32.4 Gbps bandwidth. The unit requires external USB power to function and cannot show both displays simultaneously.

Build Integration

The switch fits between DisplayPort cables and needs a standard DP 1.4 cable on each side for full performance. Total cable length across input and output should stay within three metres to avoid signal loss. A free USB port or charger is mandatory to power the box, freeing the user from manually swapping cables when changing sources.

Upgrade Context

This replaces manual cable swapping or basic single-direction selectors for users who toggle between two computers or two monitors. The jump is worth it when you need 8K 30 Hz or high-refresh 4K and 1080p switching without unplugging cables. It does not suit setups that require both displays active at the same time.

Questions about this item

Will the 32.4 Gbps bandwidth hold up during long gaming sessions?

The switch passes up to 32.4 Gbps and supports 8K at 30 Hz, 4K at 120 Hz, and 1080p at 240 Hz; sustained throughput depends on cable quality and total cable length.

Does the unit get hot or noisy when powered all day?

It has no fan and draws power only from the included USB cable, so it runs silently and stays cool during continuous use.

What cables and power source do I need before it works?

You need standard DisplayPort 1.4 cables for each connection and a USB power source for the supplied USB cable; total cable run should stay within three metres.
