However, when I plug the USB-C to HDMI adapter directly into the MacBook Air's Thunderbolt port, it works. It seems like the video signal from my MacBook Air is not being passed through the downstream Thunderbolt port in the TS3+ for some strange reason. The monitor attached to the active Displayport to HDMI adapter works, but the monitor attached to the USB-C to HDMI adapter does not. I am using an active Displayport to HDMI adapter and a USB-C to HDMI adapter. I am trying to connect my 2020 MacBook Air to two 1080p HDMI monitors through my Caldigit TS3+ dock, but I am having difficulty.

I am losing patience and hope.Is the 2020 Macbook Air able to pass a video signal through the TS3+ downstream Thunderbolt port? If it helps, this is the display I'm connecting to: KA251Q | Monitors - Tech Specs & Reviews - Acer I tried to reset the System Management Controller on my macbook by shutting down and Shift-Control-Option and the power button, and then turning it back on. Uninstall Display Drivers -> restart -> install new display drivers again -> restart -> connect Monitor + Macbook againĬlear recent items -> unplug all devices -> shut down -> reboot with command + option + s + power button -> connect everything again once logged Yes, my mouse was lagging a bit while my monitor was attempting to connect, so I think it knows it's there, but I could not connect it. After switching on my monitor and waiting for it to connect, I realised that my macbook was not registering the device.

I then connected the end of the HDMI cable to my monitor's HDMI dock. I made sure to first shut down and restart my laptop, and when fully booted connect the mini display adapter into my mac, and connect one of the HDMI cables to the adapter. However, I have connected everything up with no success.

I have always been wanting to connect my macbook air to an external monitor, so after researching the best types for macbooks, I figured connecting my macbook via HDMI to a monitor would work.
