Using a Desktop PC Comfortably with a DisplayPort to USB-C Cable (DP Alt Mode + USB)

Hello. This is Shia.
I bought a cable to connect a desktop PC that doesn't have a USB-C port supporting DP Alt Mode to a monitor with USB-C input, so I'd like to write a quick review.
The one I purchased splits USB-C into DisplayPort and USB-A. Therefore, if you are using a display with USB-C input that has a built-in USB hub function, you can not only output video via USB-C but also have the desktop PC recognize USB devices like keyboards and mice connected to the display.

What I bought

I bought a DisplayPort to USB-C cable from a manufacturer called Fairikabe.

Although it is expensive for a cable that only supports unidirectional conversion from DisplayPort to USB-C, it allows a desktop PC to connect video output and USB with a single USB-C cable, just like a laptop that supports DP Alt Mode. I think it is very convenient if you have a display with USB-C input that has a built-in USB hub function like the one below.

Review

It arrived in a surprisingly sturdy bag.

What I took out is shown below, and you can see the DisplayPort, USB-A, and two USB-C terminals.

The DisplayPort terminal looks like this, and it is printed with 'Source' so you don't make a mistake.
Connect this terminal to the video output terminal of your desktop PC.

The USB-C for connecting to the display has a display icon printed on it.

The USB-C for power supply had a lightning bolt mark on it.
This USB-C is mainly necessary when supplying power to a mobile display, and usually, it does not need to be connected.

The USB-A for communicating with USB devices connected to the display has no special markings.
Connect this to your desktop PC.

There are many terminals and it is confusing, but when connecting a desktop PC and a monitor, if you connect them as follows, video should be displayed on the monitor, and you should be able to operate the desktop PC using the keyboard and mouse connected to the display.
At least with the DELL U2723QE I am using, I was able to confirm that I could output the screen at 4K60Hz and use the keyboard and mouse without any particular problems.

Note that when I tried it on several desktop PCs, it seems that there are cases where the USB-A is incompatible with the USB controller, and there were times when the keyboard or mouse connected to the display were not recognized unless connected via a suitable USB hub.
If it does not work well, please try connecting the USB-A via a USB hub instead of connecting it directly to the USB port of the desktop PC.

(Note)
It seems there is compatibility with USB hubs, as some did not recognize the connection.
The chips installed may vary depending on the manufacturing date, but at least the following USB hubs were recognized.
If USB recognition does not work well, please try a few different USB hubs.
