M1 Macbook air + LG Ultrafine 5k & LG Ultrafine 4k

[CranBerryBlack]

I am wondering if there is a solution to output both the LG Ultrafine 5k and 4k displays using a displaylink adapter or hub from my M1 Macbook air.

Is this a possibility at all?

It should be possible. But it also depends on what 5K monitor do you have.

If you have 5K monitor with 5120x2880 resolution, then you will definitely need a Thunderbolt docking station (for connecting the 5K monitor) and a DisplayLink graphical adapter that you could connect to the docking station (for connecting the 4K monitor).

I work at i-tec Technologies, so I will let you know about our products.
You can use any of the following TB3 docking stations: https://i-tec.pro/en/shop-window/?catg=docking-stations&kon=Thunderbolt-3
And either of the following graphical adapters:

If you have a 5K monitor with 5120x1440 resolution then basically any docking station with DL-6950 chipset can be used.

I had 2x 4k60 screens connected to my MacBook Air through a Dell D6000 Dock with Display Link

@CranBerryBlack, did you have any success? I'm in a similar boat, but with two LG 4K monitors. I'm using a Wavlink UG69DK1 dual 4K docking station. But because the LGs only have usb-c inputs, I've tried to use an HDMI-USB-C cable into the Wavlink, and a Displayport-USB-C cable into the Wavlink. Neither work. The DisplayLink application does register the device (i.e., on the preferences screen, I see the orientation option, which lists the monitor name properly), but there is no image.

(The HDMI-USBC and DisplayPort-USBC cables are of the right type, intended to convert a video signal *from* HDMI/Displayport).
