UGREENRevodok Pro 209 USB C Docking Station, DisplayLink 9-in-1 Dual 4K@60hz Monitor Dock for MacBook & Windows with 2 DP & 2 HDMI, 10 Gbps USB C & USB-A Data Ports, 100W PD, Gigabit Ethernet

I'm not using this device exactly as intended, I have a somewhat different scenario so I thought I would share my success in case it helps anyone.I have an LG 5K monitor and an ultrawide, and a Caldigit Thunderbolt dock. The 5K has to be connected via Thunderbolt, there are no other options for connecting this monitor. For the M1 Air, you have two Thunderbolt/USB-C ports so you can connect the 5K directly in one port, and then this device (UGREEN's DisplayLink adapter) can go in the second port and then you can connect the monitor to that, and it would work fine (I tested this).However as you can see from my images above I wanted one cable to connect and disconnect my peripherals. So my setup has the thunderbolt wire connecting to the laptop providing power, and data. That wire goes to my Thunderbolt Dock. From there, the passthrough Thunderbolt goes to the LG 5K (on the right). The USB-C port on the Thunderbolt Dock goes to this UGREEN DisplayLink adapter. Then my second monitor connects to this DisplayLink adapter. I've connected it with both HDMI and DisplayPort and both work without issue. However I'm using DisplayPort just because I feel it provides the best picture.Steps:1. Plug in Adapter2. Click "OK" when MacOS asks if you are fine with using this accessory3. Find the folder in Finder or on your desktop that has the driver (see 3rd image)4. Install driver5. Second display should work (without restarting it).Huge disadvantage as pointed out by another user:Playing movies and TV shows from protected sources will NOT work. For example, AppleTV app, Netflix on a browser, Vudu on a browser, they will all not show any visuals anymore. I imagine this is because all that software is design to prevent people from ripping the media and this DisplayLink software probably gets flagged by its protection scheme, but I'm not sure. It didn't matter if I moved the video over to my 5K monitor which is connected via Thunderbolt, because the DisplayLink is turned on, the visuals don't work.Now what's nice is, if I do want to watch a movie, I can simply hit the power button on this UGREEN DisplayLink adapter and it turns off the device, and then the movies work.So if you watch a lot of movies and TV from legit sources, then this will not help unless you're willing to turn it off and just have one monitor work, which is possible in my setup because the first monitor doesn't connect through this device. It may not work for you.

My work uses these for connecting multiple monitors in the office, so I purchased it for home. I purchased the 100 watt Anker USB-C power adapter (no power adapter included) because I am just an Anker fan, but this setup is amazing.My monitors have the Digital Video connectors and the 4k video is amazing through this dock.I would absolutely recommend this product.

My situation was I have a MacBook Air M2 and wanted to use 2 external monitors. I bought this dock and everything worked as advertised but I eventually returned the dock because of the hidden downsides. I knew I would have to download display link but I didn't know that the software would bog my computer down greatly; and I didn't know that I could not play video from AppleTV because the DisplayLink software and since I have a bunch of purchased movies that was a dealbreaker. Fwiw, you can get around the DRM issue with most other video sites by using chrome and disabling hardware acceleration. Ultimately, the significant drop in my computer's performance plus DRM stuff made it a nah dawg from me. I ended up getting a refurb MacMini for not much more and can run 2 monitors no sweat.

The manufacturer of this device and of any other device they make will not provide technical support for people who purchased their products from Amazon. You must contact the seller for technical support. The seller and the manufacturer are not the same. Once your return date has passed, you should not expect to get any response from the seller. Therefore, you will receive zero technical support for this product.With regard to the product itself, the screen flickers in and out in some situations on a MacBook. It also mounts a drive to your computer containing nothing but links to drivers. If you eject or unmount this drive, it just remounts immediately. So you will never get rid of that drive. Again, the only thing on this drive are links. Except if you’re on windows, in which it has an auto run file… Which is probably going to run something every time you start your computer… Virus?You are much better off buying one that is just a few dollars more from a company that is reputable like Pluggable. That is what I bought to replace this one that I bought.

Initially impressions. Feels great and works perfectly allowed me to have two external monitors on my mac M1 (through display link) wish there were more usb and usb-c on the back though. Hasn’t got hot good value for money and feels like quality. Good brand

It’s on the pricey side, but it does put my two 27” LG 4K monitors running at 60hz without any issue by using thunderbolt connector from the PC end and two HDMI cables to the 4k monitors.

I have a 2023 MacBook Air with M2Working great with two 2K monitors, I used it with two 4K monitors at work and it did look like it was struggling so if you want to use two monitors I would recommend 1 of them 4K and the other one 2K at maximum.

Laptops: Dell XPS 15 (9510), MacBook Pro 16 M1 ProPrice paid: $130I got tired of plugging in my two usb-c monitors every time I need to disconnect my laptops, plus the cables seemed to be pulling too much on the port. Having one cable is great.Dell: I plugged it in and both monitors worked with no additional effort. One thing I have noticed is the power delivery is never enough. I have seen this with other docks as well. Laptops want more than 100w, but most docks only deliver 90 or so.Mac: This did need the display link software to work. What’s nice is when you plug it in, a drive mounts with links to download the software. After that, it worked great.Ports: I hooked up 2 Dell 4k monitors using display port and they work great. No flickering, no random disconnects.The ports up front are great for when I need to charge my mouse, headphones or keyboard.Overall not a bad product.
