This is a very common scenario and a lot simpler to understand and get working than a direct USB-C connection - ironically. The USB device that you connected to reported a problem, or there’s a problem with the device driver. This power delivery is typically not as much as your laptop's actual charger, but it will still charge your machine usually - just more slowly than the original charger.

Dell’s U4924DW is a curved ultrawide but has a less aggressive curve than alternatives focused on gaming, which in turn makes it more suitable for work tasks. It also benefits from a sturdy, elegant design, a small yet effective stand, and VESA mount compatibility for both 200x100mm and 100x100mm mounts. The monitor also supports picture-by-picture and picture-in-picture modes that let users view two input devices at once. It’s perfect for use in either a home or corporate office. For charging speeds we recorded the maximum wattage at which the cable could charge an Asus ROG Strix 15 gaming laptop over its USB-C port using USB-Power Delivery with an Aukey 100 watt USB-PD charger as the source while the laptop was under load.USB-PD today is limited to 100 watts (with a 240-watt spec on the way). Any USB-C to USB-C cable should handle 3 ampsat 20 volts, or 60 watts.All of the USB-C to USB-C cables fell into the standard 60-watt or 100-watt camps. If you want this cable to charge your laptop, it should support the wattage your monitor delivers over this connection. This is normally about 60 to 65W. If you have a spare cable lying around, it might not be good enough, unfortunately, as most HDMI cables don’t tell you what version they are.You’d think you could tell whether a cable is USB-C 2.0 cable by looking at the wires in the connector but that’s not the case. Some cables use connectors with pins that aren’t hooked up to anything. USB 4 has tried to avoid falling into the naming trap. There are only two versions of USB 4: USB 4, and USB 4 v2.0. Regular USB 4 has a maximum transfer rate of 40 gigabits per second, and USB v2.0 has a maximum transfer rate of 80 gigabits per second. Be aware, however, that the USB-C cable’s 20Gbps throughput may not allow for video to be passed to premium displays like the NZXT Canvas S27Q at its full 1440p, 165Hz refresh rate. Those specifications probably assume that you’re using a dedicated video port like DisplayPort, instead, as well as its separate video cable. You can certainly connect the display to your laptop using both a video cable and the USB-C cable simultaneously, however.

Dell Premium Panel Exchange * allows a free monitor replacement during the limited hardware warranty period, even if there is only a single broken pixel.

Make sure your PC (or phone), the external display, and the cable all support DisplayPort or MHL alternate modes. USB 2.0 is USB 2.0, and anywhere you see it you can be sure that you'll have a maximum transfer speed of 480 megabits per second. The LG DualUp 28MQ780-B is a USB-C monitor with a unique 16:18 aspect ratio that’s almost exactly square. It can rotate into a 18:16 aspect ratio if you’d prefer. The monitor is much taller than most monitors and, as a result, has an adjustable stand that clamps to the rear of your desk instead of a normal desktop stand. Usually, a task which should essentially be “plug this into this” becomes complex and time consuming. However, don’t let this dissuade you from accomplishing your monitor goal, just make sure you do plenty of research before buying a cable, and make sure it’s the one you need. Both USB-C to DisplayPort and USB-C to HDMI cables are, in 2020, readily available from Officeworks, JB-HiFi, most computer stores etc. All should in theory work ok for up to 4k/60hz.

The monitor’s 15.6-inch 1080p OLED panel delivers exceptional color accuracy, gamut, and contrast. It surpasses many full-sized OLED monitors and nearly all portable monitors. This makes it a great choice for productivity, though it also looks excellent when viewing movies or playing games. Dust or dirt inside the USB port on your device might be preventing the charger from being inserted correctly. The MHL Alternate Mode lets you project video and play audio on an external display that supports MHL.The best monitor with USB-C that we've tested is the Dell U2723QE. It's an impressive monitor for productivity purposes with a massive USB hub as it has three USB-C ports, each serving a different purpose. One supports DisplayPort Alt Mode with 90W of power delivery, which is the port you connect your laptop to if you want to display an image and charge it simultaneously. Another USB-C slot is a downstream port with 15W of power delivery, so you can use it to charge your phone or other small devices. The third USB-C port is an upstream port for the KVM switch, which allows you to control different devices with a single keyboard and mouse connected to one of the five USB-A ports. We didn’t test the temperature of each cable’s housing, but we did test the cheapest cable by running it at 5 amps and 20 volts for an hour. The housing heated up by 50 degrees Fahrenheit, and the cable itself became relatively warm (see the thermal image below). Not ideal, but it did this without failure. We subjected other cables to two-hour loads without failure, as well. Ideally, it should explicitly mention video support up to the resolution and speed you need... (video over USB-C is also known as 'USB-C Alternate Mode')

If your laptop uses either Thunderbolt 3 or Thunderbolt 4 or USB4 — all of which use a 40Gbps data connection and a USB-C port on your laptop — you should probably have no issues connecting your laptop to the monitor at the full refresh rate using a Thunderbolt cable. Just consult your laptop’s specifications and/or manual to make sure.
