What this product does

The BUCIER A0209 is a manual DisplayPort 1.4 bi-directional switch that routes one of three sources to a single display or one source to one of three displays. It supports 8K at 30 Hz, 4K at 144 Hz and 1080p at 240 Hz with 32.4 Gbps bandwidth. The unit is aimed at users who need to share a monitor between multiple PCs or consoles without unplugging cables.

The specification that decides fit

This switch only passes DisplayPort signals; it will not work with HDMI or USB-C sources unless an active adapter is used. Maximum combined cable length is 3 metres, so longer runs may lose signal. Only one output is active at a time, so simultaneous multi-monitor use is not possible.

Installation and common issues

The device is plug-and-play and powered externally; press the select button to change the active port and watch the indicator LEDs. If the screen flickers, reseat the cables and shorten the total cable length. No automatic switching occurs, so every change requires a manual button press.

Questions about this item

What does the 8K 30 Hz rating mean when I connect this switch to my PC and monitor?

The switch passes an 8K signal at 30 Hz, 4K at 120 Hz or 1080p at 240 Hz, provided you use certified DisplayPort 1.4 cables on both sides and keep the total cable run under three metres.

How does the DisplayPort 1.4 interface limit the resolutions I can actually run?

DisplayPort 1.4 caps the link at 32.4 Gbps, so 8K is limited to 30 Hz, 4K reaches 120 Hz and 1080p can hit 240 Hz; higher refresh rates at those resolutions would need a newer standard.

What does the unit need to sit on my desk and connect three sources?

It weighs 0.07 kg, has three female DisplayPort ports, a manual select button with status LEDs, and requires an external power adapter to operate.
