ESTONE TJ-A009 DP 1.4 Switch

The ESTONE TJ-A009 is a bi-directional DisplayPort 1.4 switch that lets you connect two sources to one display or one source to two displays. It supports 8K at 60 Hz and 4K at 120 Hz with 32.4 Gbps bandwidth for high-resolution gaming or professional work. The alloy housing provides wear and oxidation resistance while the tin-plated interfaces improve transmission efficiency. This unit requires external power via the included DC 5 V cable.

Sustained load behaviour

The switch maintains the full 32.4 Gbps link during extended sessions at 8K 60 Hz or 4K 120 Hz without signal degradation. High dynamic HDR and 10-bit colour depth remain stable across long periods of use. Audio transmission at 32-bit 1536 kHz continues without dropouts when the connection is held for hours. The manual button press swaps the active path within one second and the indicator LEDs confirm the current routing.

Installation and common issues

Plug-and-play setup needs only the DisplayPort cables and the supplied power adapter; no drivers are required. A standard DP 1.4 cable must be used on every port to achieve the rated resolutions and refresh rates. The most frequent issue is attempting to run both outputs simultaneously, which the hardware does not support — only one display is active at a time. Forgotten power connection is the other typical cause of no signal.

Questions about this item

Does the ESTONE TJ-A009 switch generate noticeable heat or fan noise when left running all day?

The unit has no fan and draws power from an external DC 5 V cable, so it runs silently and stays cool during continuous use.

Which cables and power source do I need to have on hand before the ESTONE TJ-A009 will work?

You must supply standard DisplayPort 1.4 cables for each connection and a free USB port or 5 V wall adapter for the included DC power cable.

Can I keep my older 1080p 144 Hz monitor connected through the ESTONE TJ-A009 alongside a new 4K 120 Hz display?

Yes, the switch is backward compatible with earlier DisplayPort standards and supports 1080p at up to 240 Hz, so the older monitor will work when selected.
