Plugable4K DisplayPort and HDMI Dual Monitor Adapter for USB 3.0 and USB-C, Compatible with Windows and ChromeOS

After installing the DisplayLink driver, this works perfectly for adding a third external monitor to an M4 Macbook Air. I'm able to connect two monitors to my CalDigit TS3 Plus, then also connect this dongle to the CalDigit, for a total of three monitors (plus the built-in screen), using only one cable connected to the laptop.I did notice some stuttering on the (1440p) monitor connected through this dongle, but after changing its refresh rate in my display settings from the default 70hz to 60hz, the stuttering went away. There is a slight increase in latency and I'm not willing to say that the smoothness is 100% as good as the natively-connected monitors, but it's so good that I have a hard time discerning any difference.Be aware that Apple's "True Tone" feature does not apply to the monitor connected through this, so you'll need to disable it, or else one screen will have a neutral white balance and the other screens will get orangey in dim environments. Also be aware that the DisplayLink driver consumes CPU, depending on how much activity there is on the monitor connected through this dongle. When I run full-screen 1440p video, it consumes about 40% of one CPU core. With every office tasks, it's 10% or less. With a Youtube video playing just in one corner of an otherwise-static screen, it's about 15% of one core. Since I have ten cores, that seems like an acceptable tradeoff.

Worked great right out of the box. I run 4 monitors from a single computer, purchased 2 of these units to drive those monitors, and am one happy camper.

I never knew something like this existed!! Life saver!!! Does not require an electrical outlet like others, space saver, easy installation, great value for the cost. You can’t bet this!! Yes I do recommend!!

Works great for MacBook air and Windows laptop. Tried this on an HP i5 laptop, 2020, M2, and M3 MacBook air and so far all works and looks great! Feels solid and easy to set up. Make sure you download the driver's and easy peasy!

it arrived on time but the device is getting warm, and it is not allowing a signal to pass through the monitors.

Allows my Macbook M4 pro to utilize 2 external monitors in addition to one connected directly to the Mac's HDMI port, while also using the internal display. Just have to have DisplayLink Manager running. Works flawlessly.

Works great with my MacBook Air

If I was given the option of going down to only one external monitor or using this to get two monitors? I'd go down to one and use this as a coaster for my drink.I have a late 2019 15-inch Macbook Pro, running macOS 12.4 Monterey, 2.6 GHz 6-Core Intel Core i7. Not the newest computer but it does GREAT for work (internet browsing, a few programs, and emails)I was previously using 2 Apple USB-C AV Multiport Display adapters when I bought this. Each took up a port for my two 32" 4k monitors. I got this to try and reduce to only one port being used for both monitors for no other reason than to minimize and declutter my desk space.I downloaded the latest driver/support software for this after realizing "Plugable" was not the same as "plug and play" where it just works after plugging it in (like all my other adapters) Not a big deal however, and that's my fault for not reading the full description for this and absent-mindedly thinking that was part of their shtick on that name choice. Hey-o!Does it work? Yes. I got both monitors up and running in about 5 minutes.Does it work *well*? NO. Not even remotely well.SIGNIFICANTLY slower performance on both monitors (and the computer itself) than using two Apple adapters.At one point I thought my internet had gone down or was going down because of how poor the experience was. I had to verify on my phone that it wasn't the internet going down. We're talking normal website and email usage; I'm not over here streaming movies or broadcasting on Twitch all day. The mouse chugged and skipped around the screens like it was 1995 all over again and all the display settings were the same and optimized.It severely increased the battery drain:Without plugged into the power source my MacBook usually goes several hours on normal use. With this plugged in? It went from full battery to completely dead in about 30-45 minutes and it was only actively being used for 15 min of that...the rest was idling while I did my morning routine in the house.I had this sitting on my desk for a week before I finally switched over to using it and I had forgot how much I (over)paid for it. Returned immediately. Couldn't work a whole day with this. This may or may not be a good solution for PC people, but the price for this isn't even remotely worth what you get for it on a Mac.
