So...my laptop is fully TB4 and capable of high refresh rate displays, with DP 1.4 output via USB-C/TB4, and I have a good gaming monitor that is DP1.4 and high refresh at 144hz....but couldnt get the dock to connect the monitor on either DP or HDMI at 144. With the DP, it may be due to the USB-C to DP adapter they included - potentially its not a TB4 compatible adapter? Further, the USB 3.0 ports are underpowered and wont drive an external webcam with integrated ring light - the web cam works just fine if plugged directly into my laptop, but wont work when plugged into the docking station. Finally, network adapter not recognized, either. Simply put, having to return this because, well, it just doesnt work...I guess there was a reason it was on a big sale yesterday. Will have to look for another TB4 docking solution....ugh.

Works as intended and solid product for its price!

Works great to connect a laptop, phone or tablet with a USB C output to a TV or projector with an HDMI input. Compact design. Could not ask for more.

The seller has updated this product, so I am updating my review. This USB-C dock is not what I reviewed. I reviewed a small dongle that was under $20, not a dock that is north of $200. This adapter does its job. I bought a desktop that only had USB-C without realizing it, and this gave me the connection I needed to get to my HDMI monitor. Picture quality is great and it sends through the signal at full resolution.

Did extensive research on an accessory to my M2Pro MacMini which would provide: a) Thunderbolt 4 front panel access to connect an external hard drive or other accessories that can handle up to Thunderbolt 4 rated data transfers, b) slots for SD & TF cards, and c) USB 3.0 ports for other accessories and flash drives. The MacMini has all its I/O ports on the back side of the computer which is a hassle when attempting to connect temporarily an accessory or portable hard drive. It also has no SD card slot. The IVIIN Thunderbolt 4 Docking Station is a great addition to a MacMini. The robust power supply and separate on/off power are great features which will ensure reliable connections between external accessories and my MacMini. The IVIIN Thunderbolt 4 Docking Station also provides, on the back side, a Thunderbolt 4 port, three USB 3.0 ports, and an HDMI port for more permanent accessory installations. The Docking Station also includes a USB-C to HDMI dongle for connecting a second display monitor. The installation was exceptionally simple - plug-in and play! No drivers needed. No Hassle! Overall, the IVIIN Thunderbolt 4 Docking Station is a great value addition to my MacMini providing me with exceptional flexibility in connecting accessories.

I needed an adapter to connect tablet to HDMI and this works perfectly. It will also be great for iPhone 15 that will change charging port.

This handy adapter does exactly what its supposed to do! Works as advertised and handy to have around and in my travel bag.

used this to connect an hdmi to my work pc, performs the intended function. not much else to say!

The USB C to HDMI adapter is very useful for me as I volunteer for my communitys television station and we often have to live stream and send a great deal of data transmission to a display screen. It has to have super speed to prevent lagging making it possible to even stream videos. Although I havent tried it, it states that it should also have a high resolution that can even support 3D gaming.

It is very lightweight yet the chord is very sturdy and well protected. Works perfect with my Mac. Best value you can get at this price!
