Which dock, laptop, display? Does the dock do anything? USB peripherals work? Network works?

I am new to using the Club 3d docking station.  I previously had a Dell docking station.  New laptop as well, Acer Nitro V15.  My cooling fan is plugged into the docking station.  My Acer monitor is the only item not working.

List the model numbers of your docking station, laptop, and display.

There are many Acer Nitro V15 models.

Club-3D has multiple docks.

Different displays may have different HDMI requirements.

Is it the Club 3D CSV-1564W65 USB Gen1 Type-C Triple Display Dynamic PD Charging Dock ?

The CSV-1564W65 appears to use a DisplayPort 1.2 MST hub limited to two lanes of HBR2. The total pixel clock for all displays must be less than 360 MHz (assuming RGB 8bpc).

You are connecting only one HDMI display so it should be able to handle 4K30 (297 MHz HDMI) or 1440p60 or 1080p120.

The CSV-1564W65 must be connected using a USB-C 5 Gbps or 10 Gbps or 20 Gbps or passive Thunderbolt 3 or 4 or 5 cable to a USB-C or Thunderbolt or USB4 port that supports USB-C DisplayPort Alt Mode.

A charging cable is not sufficient. You should be able to connect USB devices up to 5 Gbps to the dock. If that’s true, then the cable is ok.

Is your Acer model number this: Acer Nitro V 15 ANV15-51-50Z1 | NH.QNAAA.003 with RTX™ 2050? It appears that the only USB-C DisplayPort Alt Mode capable port is the Thunderbolt 4 port.

Do you have any USB-C to DisplayPort or HDMI adapters or cables that can be used to test the video output of the Thunderbolt port?

On my docking station, there is only one port for an HDMI Cable.
