But to display an image, you'll also need a PC capable of USB C alternate mode (even though this isn't explicitely mentioned in the LG manual, but that's the only way DisplayPort can be transported via USB C). So yes, for data only, it can use USB 2.0. Please connect the USB C-C or USB C-A cable to the PC. The USB port on the product functions as a USB hub.

In that case, an USB 2.0 to USB-C adapter will work.īut there's nothing in the manual that indicates it will do that, so the only way to find out is to either ask Dell, or try it out. Now it might be possible that the USB controller in the monitor is really really smart, and also supports an USB 2.0 connection, without power delivery or display port signals, where it just acts as a simple USB hub. So it's not only a USB-C type port, it also needs alternate mode, so the USB host adapter in the computer you plug it into must be capable of this mode (and not all host adapters are).
9ġx USB Type C (Alternate mode with DP1.2, USBģ.1 upstream port, Power Delivery PD up to 45W) Overall similar in terms of ports but it has a built-in kvm switch so I have to change no cables at all. Now I've started using Dell U3419W and it's even better. This was my initial assumption as this was always the case when a built in display upstream USB port was of an older type USB-A (regardless 2.0 or 3.0).Ģ020 EDIT: I'd gone with Lenovo ThinkVision P27h monitor for quite a while and it worked as I wanted it to. This would surely exclude it.Ĭonclusion: such a setup is possible, it's wrong though to assume an USB-C upstream with USB 3.0 downstream ports built in display imply the display does have an USB hub. The predecessor of my laptop was not charging when connected to this display model. USB-C upstream port on the S2718D display is not capable of acting as a HubĪnd as I've found out the LG could do it, I can turn to pick this one. Perhaps it's worth mentioning, this display supports charging over USB-C (45 Watt) and I would like to use this feature for charging laptop, not sure wouldn't it 'try charging' the desktop PC over the adapter and damage it.Ī relevant piece from LG 27UD88 display user manual for the discussion in comments.ĮDIT2: I've got an answer from DELL customer service so if anyone was interested it's no. Type C connector can support Reversible plug orientation and Cable direction. Type C connector is the new design for USB 3.1 and can support charging and data transfer. This adapter can convert the data which is USB-C head used into the ordinary USB 3.0 data cable. USB-C USB 3.1 Type C Female to USB 3.0 A Male Data Adapter for Macbook Tablet Mobile Phone How about the peripherals though? Is there any chance it would work if a female USB-C to male USB 3.0 adapter or cable was used between the desktop and the display? If there is no chance, any other solution? Input source is not an issue as desktop would be connected over HDMI.
Now comes the tricky part, desktop PC doesn't have an USB-C port. I would like being able to switch the display between the laptop and a desktop PC with the least cable swapping possible whilst peripherals (mouse and keyboard) stay connected to the monitor's USB downstream ports. Let say I would pick DELL S2718D display. As I need to buy a new display anyway, I wanted to make my life easier with an USB-C one cable connection to my laptop (Razer Blade Stealth, it shouldn't matter for the question though).
