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. Power Delivery 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. You could potentially find a VGA to HDMI converter but they’re usually disproportionately costly for the quality of the connection you experience in the end. You might find that occasionally monitors will have an additional port to allow you to connect the signal from your device to each monitor by “daisy chaining” from one monitor to the next, although it’s worth pointing out this isn’t very common. One of the major advantages of DisplayPort over USB-C is that you can use it more easily in newer, slimmer devices such as notebooks, tablets, phones, or displays. Since the USB Type-C connector is the latest USB interface that almost all new devices sport, this reduces the number of ports required on any one device.
That’s not all. The GW2790T has built-in speakers and a microphone, which makes it an all-in-one video conferencing display. The microphone admittedly isn’t the best, but it’s fine for video conferencing. Your PC has a low battery, so it has temporarily limited the amount of power it can provide to the device. No video data will be received by the display, hence there will be no image on the screen. Doing this will not harm your device. A warning message might also be displayed on the screen of the USB product to notify the user about the incompatibility. Connectivity is excellent. The monitor has a USB-C port with DisplayPort Alternate Mode and up to 90 watts of Power Delivery for charging a connected device. It also drives a USB hub with a total of five additional USB-A ports, ethernet, and DisplayPort-out. That’s enough to connect a wired mouse, keyboard, and display—and still have several ports left over for external drives or your smartphone.Make sure your PC (or phone), the external display, and the cable all support DisplayPort or MHL alternate modes. Your PC might not provide enough power to the USB device. Please connect your device to external power, or try using a different PC.
Make sure the device or dongle is connected to the USB-C port on your PC that supports the correct Alternate Mode. For example, if you're connecting a Thunderbolt Alternate Mode device, make sure you connect to the USB-C port that supports Thunderbolt™. What you are specifically looking for, then, is a video capable USB-C cable that supports up to the video throughput you need (usually these mention 10Gbps speeds and video, AKA 'alt-mode' support). The main issue with these cables, apart from their age, is that they don't support audio transmissions, so you’ll need to connect a separate audio connector to rig yourself up properly. 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. The Asus ProArt PA348CGV is a spectacular ultrawide USB-C monitor. It manages to serve a huge range of people, from gamers to prosumers and professionals, without letting anyone down.A PC with USB Type-C connectors has larger power limits. If the connector supports USB Power Delivery, it can charge even faster at greater power levels.
To get this working, though, you need to be very careful with cable selection. If your monitor comes with a USB-C cable, then this is the obvious choice of cable to use, and should 'just work'. However not every monitor comes with every cable.The Alternate Mode feature must be supported on the PC or phone's hardware and software, and the connected device or dongle. You might also need a specific USB-C cable. The monitor cable types used to connect displays to desktop and laptop PCs have changed dramatically over the years. There have been improvements in bandwidth and reductions in latency, and hosts of new features introduced. Where older cables could only transmit low-resolution analog video, more modern cables can transmit digital video and audio. Some can even handle power as well, while others let you do advanced daisy-chaining of multiple monitors on a single string of cables.
Notes: USB Type-C has a new feature called Alternate Modes which allows you to use non-USB connections with the USB-C cable and connection. There's no setting to turn on—your device automatically uses the appropriate mode if it's supported. Here are the display Alternate Modes that your cable may support: Again, it has standard looks and doesn’t have fancy frills like the braided exterior, textured connectors, and the likes. It’s a simple USB-C to DisplayPort cable, and that’s about it. 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.In addition to his extensive writing experience, Chris has been interviewed as a technology expert on TV news and radio shows. He gave advice on dark web scans on Miami's NBC 6, discussed Windows XP's demise on WGN-TV's Midday News in Chicago, and shared his CES experiences on WJR-AM's Guy Gordon Show in Detroit. Make sure the device or dongle is connected to the USB-C port on your PC (or phone) that supports the correct Alternate Mode. For example, a DisplayPort Alternate Mode adapter should be connected to the USB-C port on your PC (or phone) that supports DisplayPort Alternate Mode. The USB device that you connected to reported a problem, or there’s a problem with the device driver.
