Q: I have an issue with my thunderbolt 4 dock that when i plug in a usb hub to a usb port on the dock, that only some devices work. same with this one?

Same issue here. I have two 16-port USB hubs that worked fine with the T3. After updating to the T4 with an M2 Mac, it failed to recognize any device in either of the two 16-port USB 3.0 hubs while plugged into any of the 4 USB Type A connectors on the back of the T4. I did solve this though, by using a Type A to USB C adapter on the two 16-port hub cables and plugging them into the two FRONT USB-C connectors. While not an ideal location, all devices on both of the 16-port hubs are now seen and seem to operate without issue. I believe they would have worked also on the USB-C/Thunderbolt 4 connectors on the back of the T4, however, I have two external drives connected to those.

Q: I want to connect 4 monitors to my M1 Max, will this going to help me?

M2 silicon supports various configurations depending on which one you have. You can connect 1 monitor to 1 thunderbolt port, then a second monitor to the display port (use an adapter if the monitor doesn't have a display port) finally connect the 3rd monitor to a second thunderbolt port. This is a slight issue it seems with the TS4 firmware. remember the m2 pro chip only supports 2 external monitors while the max chip supports 4.

Q: Can the TS4 operate without the power adapter plug in?

I always enjoy reading the Questions asked here on AMZ. Reviews can also be as entertaining. Can the TS4 operate without the power adapter plug in? with its 98watts to charge your laptop along with up to 20W USB-C ports - where would all this power come from one might ask? Alas, it comes with 1 x Power Supply (230W) to the rescue! Note: Requires macOS 11.4 (Big Sur) or above.

Q: Will this support simultaneous use of two lg ultrafine 5k displays with a 2021 m1 macbook pro 14?

NO! NO IT CAN NOT. I have an M1 Max 16" MBP, two 27MD5KL LG Ultrafine 5K monitors (the ones available through the Apple Store), and they do NOT work with the TS4. Had this confirmed by CalDigit Tech Support. Check out my forthcoming review here on this topic. MBP has 3 TB4 cables connected to it: one to each of the two monitors, and one to the TS4. FYI/FWIW: Somewhere along the line, perhaps somewhere on the Apple site, I read that dual monitors must be plugged into TB4 ports on opposite sides of the MBP, one on each side. Doing it this way, I do seem to get crisper resolution vs plugging both into the left side.
