Review on 💻 Cable Matters USB C Hub with HDMI 4K, 80W Charging, Gigabit Ethernet, and 3X USB in Black - Thunderbolt 4/USB4/Thunderbolt 3 Compatible Dock for Surface Pro 7, MacBook Pro, Dell XPS by Richard Payne

Short story. I've been using this adapter as a dock replacement for a few months. It worked fine with my BIOS version 1.8.0. (I'm having trouble with BIOS version 1.6.3.) I just plug in my computer and my monitor, keyboard, sound, and power supply work. It sleeps and wakes up. And it works with closed or open laptop. When I restart I get a warning that the power output is 40w and not the 45w my computer can max out, but it works and charges the battery well. Buyer information: When you buy this hub/multi adapter, you should be aware of "Alt Mode" and "DisplayLink". These are two different ways for the computer to send video to the adapter via USB-C. (The adapter then converts the video to send over HDMI, DVI, RGB, etc.) This device uses DisplayPort Alternate Mode, also known as Alternate Mode. Alternate mode is natively supported by my computer hardware. Some other devices use "DisplayLink" which is different and requires a separate software driver. DisplayLink will probably work on all computers, but the driver uses the processor. You can usually tell if an HDMI device is using Alternate Mode if it says it only supports 4K monitors at 30fps; DisplayLink normally does 60 frames per second. (This may change after 2019 when Alt-Mode devices support newer versions of the HDMI standard that provide 4K at 60 fps.) Alt-Mode supports only 1 monitor in its base version; Your hardware must support "MST" ("Multi-Streaming") in order to use multiple monitors via a single USB-C port. (Also, check if the adapter supports multiple monitors—some have VGA, HDMI, and DisplayPort, but you can only use one at a time.) "DisplayLink" always supports multiple monitors. No technology is the "best" - each has compromises. My settings: My computer is a Dell XPS 13 (2018 model 9370) running Ubuntu 18.04.2. BIOS version 1.8.0. I'm not sure what version my Thunderbolt firmware is, but it's at least version 33.00. The computer's power adapter (45W) is connected to the USB-C pass-through power connector. HDMI port connected to my monitor: Dell U2415 at 1920x1200. USB ports connected to Yeti Blue microphone and Apple aluminum keyboard. An Apple Mighty Mouse is connected to the keyboard. I don't use Ethernet on a daily basis, but I've only tested Ethernet separately and it worked fine. When I used version 1.6.3 of the BIOS I actually had problems. When my device was on and I had an adapter plugged in with the HDMI already connected, it didn't work. (The monitor never woke up. "xrandr" didn't show the DP-1 device.) When everything was plugged in and my computer went to sleep when the computer woke up, the monitor stayed in sleep mode. ("xrandr" showed a "DP-1" device. The mouse pointer and window manager behaved as if it were still connected, but the external monitor remained idle and black.) Both issues were resolved by the HDMI cable was disconnected and then reconnected. Video quality is good. I notice a slight lag when playing games like Minecraft, but I haven't noticed it when using work apps like Emacs etc. I bought this adapter again so I can keep it in my travel bag for presentations.
