There are two variants of the Plugable DisplayLink 4K DisplayPort and HDMI Dual Monitor Adapter. One with 1Gbps Ethernet Port (USBC-6950UE) and one without (USBC-6950U).
My guess is the one without an Ethernet port should be cheaper, but sadly I can’t find it on Amazon.sg. I only found the one with an Ethernet port on Amazon.sg retailing for S$139. After a 5% discount voucher, I got it for S$132.05.
I love Amazon.sg’s delivery, especially when I am a prime member. I ordered it at 8.30 pm on 7th April 2022, and I received it the next day at 12:30 pm.
I am using the 16″ MacBook Pro with an M1 Pro chip. So the maximum number of external monitors it can support is just two. However, I have three external monitors on my desk. So I got this Plugable DisplayLink 4K DisplayPort and HDMI Dual Monitor adapter to use three monitors with my M1 Pro MacBook Pro.
It uses the DisplayLink DL-6950, which supports dual 4K monitors at 60 Hz via HDMI and/or DisplayPort. HDMI version is 2.0 while DisplayPort version is 1.2.
I don’t have an Ethernet port near my working desk, so I am not using the Ethernet port at all.
You have to download and install the DisplayLink Manager app for Mac, connect your monitor cables to the device, and plug the device into your Mac. That is it. Your Mac will auto-detect it as any regular monitor, and you can rearrange it in any way you like.
The Plugable DisplayLink 4K DisplayPort and HDMI Dual Monitor Adapter work flawlessly, which surprises me.
There is no lag when using it with my M1 Pro 16″ MacBook Pro with triple external monitors. I am impressed.
After knowing that the Plugable DisplayLink 4K DisplayPort and HDMI Dual Monitor Adapter work as advertised, I bought another one for my wife. So she can use it with her MacBook Air with an M1 chip, and she can use it with two external monitors instead of just one as limited by the chip.
Similarly, there is no lag on the M1 MacBook Air with dual external monitors.
I highly recommend the Plugable DisplayLink 4K DisplayPort and HDMI Dual Monitor Adapter if you want to extend beyond the number of external monitors limited by the M1 chip.
