Possible to connect to monitor (HP Z27) with Display Port and carry USB data?

[benfrain]

I currently have a HP Z27 monitor. It has a USB-C/thunderbolt connector which is connected to a MacBook pro.

A standard keyboard and mouse are connected to the monitor with USB-A

I would like to connect a 10th Gen NUC to this monitor and share the keyboard and mouse with it.

If I connect the NUC to the monitor via a thunderbolt out on NUC => display port in on monitor, should that carry USB data back and forth? Or would I also need to connect an additional USB lead between the two?

My analysis,

1. If the monitor has a USB-C/Thunderbolt input, you can use a USB-C-to-USB-C straight-thru cable to pass both the DisplayPort and USB 3.x signals to the monitor. If the monitor then shares the keyboard and mouse with the NUC and Mac (whichever is "active"), you should be good to go.
2. If, on the other hand, you use a USB-C-to-DisplayPort dongle or cable from the NUC, the DisplayPort signals will be isolated and only they will be passed to the monitor.
3. If you have a monitor with separate DisplayPort and USB 3.x (Type B) inputs, you can use a USB-C Hub to split apart the DisplayPort and USB 3.x signals and then pass both, using separate cables, to the monitor.

I presume that you will use #1.

Hope this helps,

Not sure if this is a limitation with the monitor. It seems that the USB hub part of the monitor is unable to be shared with more than one 'input' device.

The MacBook has the USB-C/Thunderbolt connection so USB KB/mouse connected to the monitor work fine

However I connect the NUC to the monitor alongside, it doesn't seem to pick up on the KB/mouse connected to the monitor.

I have tried:

• HDMI out from NUC to HDMI in on monitor, with USB-C out from NUC to USB-C on monitor (the HP has two USB-C ports)
• HDMI out from NUC to HDMI in on monitor, with USB-A out from NUC to USB-A in on monitor

However, the USB A => USB A cable I have tried is very old. I've ordered a new USB3 A => A to try.

Likewise I am unsure if the extra USBC => USBC cable is actually a Thunderbolt cable (suspect not) so I have ordered a Thunderbolt 3 cable to test too.

Will update findings here for completeness although I think this is actually nothing to do with the NUC and more to do with the monitor!
