If you choose High Data Speed, then the display will run USB 3.x over USB-C, but in that case you'll need an HBR3 system if you want to run 4K 60 Hz. If you set it to High Resolution, then it allocates all lanes to video so that even an HBR2 system can run 4K 60 Hz over USB-C - but then you only get USB 2.0 speeds from anything plugged into the display's USB ports, since USB-C connectors have pins dedicated to USB 2.0, which means carrying that doesn't affect display bandwidth. That's why the U2720Q offers a "USB-C Prioritization" setting in its on-screen menu.

If you have a system that supports DisplayPort HBR3 (DP 1.3/1.4) over USB-C, then half of a full link is still enough to run 4K 60 Hz, but half of an HBR2 link is not.

The reason that matters is that when you set up a USB-C link to carry USB 3.x, that consumes two of the four high speed lanes within the cable, which cuts your available video bandwidth in half. It is also absolutely possible to run 4K 60 Hz over regular USB-C even from a system that only supports DisplayPort HBR2 (DP 1.2) over USB-C, so long as you are not ALSO trying to carry USB 3.x at the same time on that cable.

And in fact the manual clearly shows an example of connecting the display to a system via a regular USB-C cable. It can carry all of those things over a USB-C to USB-C cable. The spec they quoted in the manual does not mean that the USB-C connection can only support video, power, and USB 3.x when using adapters/dongles for each of those things. Applications do not cause the entire system to change its resolution or aspect ratio (except maybe games that run full screen), and the USB-C input is not necessarily expected to be connected using dongles. This seems to happen a lot when they try to answer even moderately technical questions. You confirm I hate to say this (although I can't say I'm surprised), but Dell Cares is completely wrong in their answer. and remember you provide the cable in the box! So, basically, USB-C Power Delivery port is useless because by design it doesn't work well. When we say that USB C to USB C is not recommended, that's because this type of port will not give you as much resolution as the Display port connectivity. The part where it says: 1 x USB Type-C (Alternate Mode with Display Port 1.4, USB 3.1 upstream port, Power Delivery upto 90W*). You can check this page under the tech specs for this monitor. Depending on the system that you have connected to the monitor, the resolution will get automatically switch to one that will allow to run the application with no problems.Īs for why it only correctly works with the USB C to Display port, that's because this monitor works with dongles or adapters while using that port and is not going to perform correctly when using a USB C to USB C cable. As some applications may not run in 4K as they were no developed to run in those resolution. The aspect ratio or the resolution will depend on the window or application that you are currently opening. Very very disappointing.Īlso I'm talking with someone of the Dell Care that said me:

So you're saying Apple computers are not officially supported by Dell, then you can't assure the Dell monitors work correctly? If so, I think you should put this very clear in the product page on your website, cause otherwise we assume that it's obviously that a monitor work on a Mac. Please, someone have never seen this thing? I need to solve as soon as possible Then, after sometime I rechecked the System info and.Īlso, I will need to use the USB Type-C cable (C to C) for the charging feature (PD port).

I especially noticed when scrolling webpages, moving cursor, dragging windows. I noticed that randomly it's pretty slow. That I connect to my new Dell U2720Q (just arrived some days ago) with the U2720Q USB Type-C cable (C to C). MacBook Pro (15-inch, 2018) with macOS Catalina 10.15.4
