Elitebook 840 G4 / Universal Docking Station / USB transfer rate

HP Recommended
Elitebook 840 G4

Hello,

I've read the threads asking about the Elitebook 840 G4's compatibility with HP docking station, but what about universal ones? I purchased this with 2 external monitors, only to learn afterward that the various USB ports aren't compatible with this docking station because it needs a transfer rate of 10 Mbps. The computer does not even recognize that there are additional displays connected to it, but it does connect to the wireless mouse via the docking station.

 

I feel like I'm getting conflicting information on the differences between USB 3, USB 3.1, USB 3.1 Gen2, and USB C (though I know this is the port shaped like a thunderbolt). My Elitebook specs say USB 3.1 (which some websites say has a 10 Mbps transfer rate and others say has a 5 Mbps transfer rate). I know the USB C only has a transfer rate of 5. So, I bought this cable to connect the USB 3.1 to the dock instead of using the USB C cable that it came with. Still no luck. 

 

Since I haven't had luck with the cable, is there any way to upgrade the ports in the computer itself to accomplish this? If so, would I have to install additional firmware or drivers?

Any help is greatly appreciated. Thank you

Specs for the series

which says it has

 

(2) USB 3.1 Gen (1 charging)
(1) 1 USB-C (Up to 5 Gbps data transfer and 15 W power)
(1) DisplayPort 1.2
(1) VGA
(1) RJ-45 (Ethernet)
(1) Docking connector
(1) Headphone/microphone combo
(1) AC

 

That USB-C prort won't work with the dock you have. If you wish to connect to 2 external monitors, all you need for your machine is any USB-A dock which is DisplayLink Certified. Please enter your requirement on the following link and it will find for you few options on market today including some HP products:

840 G4 The USB-C interface of this model is only a basic data transmission function and does not support video output.
You can use the docking station based on the displaylink chip (need to install the displaylink driver)

Thank you for your reply,

I understand that it's not compatible with the docking station as is. But what about upgrading the USB port itself in the computer? This video shows how to replace it on other models, but my model isn't listed. Can it be upgraded so that the transfer rate is 10 instead of 5 Mbps?

Thanks again,

Elisa

Unfortunately, this idea cannot be realized.
The USB interface in the video is the USB-A interface on the left side of the computer, which is only the basic USB data transmission function and does not support other additional functions.
Maybe you can buy a new computer. The USB-C interface of EliteBook 8x0 G5/G6/G7 provides more functions. G4 is old.
