Questions about this item
What is the maximum bandwidth the ESTONE TJ-A038 can sustain across both outputs?
The ESTONE TJ-A038 provides a high-speed bandwidth of 32.4Gbps over its DisplayPort 1.4 input, shared between the DP 1.4 and HDMI 2.1 outputs.
Does the ESTONE TJ-A038 need active cooling or generate noticeable heat during all-day operation?
The unit is passively cooled with no fan; it draws power from the included DC 5V USB cable and remains cool under continuous use.
Which cable and source port must I already have to run dual 4K@120Hz displays on this switch?
You need a DisplayPort 1.4 source port and a certified DP 1.4 cable for the input, plus one HDMI 2.1 cable and one DP 1.4 cable for the two outputs.
