Bi-directional DisplayPort 1.4 switch

This QYENPOQA DP21 AB switch connects two DisplayPort sources to one monitor or one source to two monitors. Only one display is active at a time and switching is manual via the select button. It is built for users who need to share a single high-resolution screen between two computers.

8K60 Hz and 4K144 Hz headroom

The unit passes 8K at 60 Hz, 4K at 144 Hz, 4K at 120 Hz and 1080p at 240 Hz with a 32 Gbps bandwidth ceiling. Total cable length must stay within 2 metres using standard DP1.4 cables, otherwise flicker or signal loss occurs. It does not support simultaneous multi-screen output.

USB-C power for signal stability

A USB-C power input is provided to reinforce the link when long cables or marginal sources cause dropouts. The aluminium shell measures 7.2 by 5 by 1.5 cm and weighs 0.091 kg. Compatibility issues are noted with the HP ZR30W monitor, which should not be connected.

Questions about this item

Will this DP21 AB switch work with my older DisplayPort 1.2 graphics card and monitor?

Yes, it is backward compatible with earlier DisplayPort standards, so a DP 1.2 source and display will function at their native resolutions.

How do I confirm the switch is passing an 8K 60 Hz signal correctly after I connect everything?

Press the SELECT button to choose the active input, then verify the resolution and refresh rate in your operating system display settings or the monitor on-screen menu.

What cables come in the box with the iron-shell DP21 AB, and what must I provide myself?

The package includes the switch only; you must supply standard DisplayPort 1.4 cables for each connection, keeping total cable length under 2 metres.
