Follow these instructions to set up your Dell UltraSharp monitor using a USB-C connection.
Figure 1
Picture in Picture (PIP) and Picture by Picture (PBP) lets you use your monitor simultaneously with two computers connected to the monitor. The KVM feature lets the user control up to two computers from a single set of keyboard and mice connected to the monitor.
Some large-screen Dell Ultrasharp USB-C monitors come with these features to help users maximize their productivity.
Dell Ultrasharp Monitor with USB-C | PIP or PBP | KVM |
---|---|---|
U3219Q | Yes | Yes |
U4320Q | Yes | No |
U4919DW | Yes | Yes |
See the documentation of your Dell monitor for step-by-step instructions to set up PIP, PBP, or KVM Switch.
The USB-C cable provided with your Mac may not support both video and charging simultaneously. Use the USB-C or Thunderbolt 3 cable that is shipped with your Dell monitor.
Depending on the model, not all USB-C ports on the monitor support a power delivery feature to charge your Mac. Always connect to the USB-C port with power delivery logo (65 W or 90 W) on the monitor. See Table 1 for more information about power delivery support on Dell UltraSharp monitors with USB-C. For example, the Dell UltraSharp U3219Q monitor supports up to 90 W power delivery through USB-C (Figure 2).

Yes, it can charge your Mac. However, the time required to fully charge your Mac is longer if your Mac requires more than 65 W or 90 W. If your Mac requires more than 65 W or 90 W, we recommend using the power adapter provided with your Mac for optimized charging.
Ensure that the display resolution in System Preferences is set to Default and not Scaled.
Try setting larger fonts in your Mac's System Preferences. Go to your Mac's System Preferences > Display and then select Larger Text from the Display tab.
macOS does not allow users to control the sound volume or screen brightness of externally connected devices using the computer's keyboard controls. Use the monitor's OSD control buttons to adjust the speaker volume or screen brightness.
Dell does not recommend using a third-party dock or adapter to connect your Ultrasharp monitor with a Mac computer.
Depending on the UltraSharp monitor model, the supported USB bandwidth over a USB-C connection is either USB 2.0 or USB 3.0. Using USB 3.0 devices such as webcam, or Ethernet adapter on monitors that only support USB 2.0 speeds over USB-C may lead to intermittent performance of the connected devices.
Some Dell UltraSharp monitors (for example, U2719DC) allow users to switch the USB bandwidth over USB-C from USB 2.0 to 3.0 using USB-C Prioritization setting > High Data Speed. See the documentation of your Dell monitor. For example, the USB-C Prioritization option in the U2719HC OSD menu (Figure 3).
