Usb-c Port Monitor

[Irati Klute]

USBC ports on monitors are useful for connecting USB-C laptops directly to your display. Unlike other video connection types, most USB-C monitors also deliver power to the source, so you can charge your laptop and display an image using a single cable. However, it's important to remember that not all monitors deliver the same amount of power, as some don't have enough to charge your laptop while using it, and with those monitors, you'll still need an external power source. USB-C can also serve as an upstream port, meaning you can connect your hard drive or other USB devices to the monitor and transfer data to your computer.

Besides its USB-C features and power delivery, you should consider your budget and what you need the monitor for when looking for a USB-C monitor. Getting a high-resolution display with sharp text clarity is useful for office work, and one with great image accuracy is beneficial for content creation.

We've bought and tested over 315 monitors, and below, you'll find our picks for the best USB-C monitors, including the best 4k USB-C monitor. You can also check our recommendations for the best monitors for MacBook Pro and MacBook Air, the best office monitors, and the best 4k monitors. You can read more about USB-C here.

Note: We recently published Test Bench 2.0 and are in the process of updating our reviews to reflect this. As such, it may seem that two similar monitors have very different scores, but scores aren't comparable between different test benches.

The best monitor with USB-C that we've tested is the Acer Nitro XV275K P3biipruzx. Its USB-C port delivers 90W of power and supports DisplayPort Alt Mode, so you can charge most laptops and display an image from your computer with a single cable. It also has two USB-A ports. Once you connect to the monitor with a single cable, you'll find its performance to be excellent for almost anything you want to do. If you're using it for productivity tasks, it has fantastic text clarity, and the monitor gets very bright, so you won't have any trouble seeing content clearly in a bright room. It also has fantastic ergonomics, so it's easy to share your monitor with someone else, whether it's for work or while watching a movie. Additionally, it's great for professional editing with its extremely accurate sRGB mode.

The Acer also has fantastic HDR performance. It gets bright enough for highlights to pop against the rest of the image, which is great if you're editing HDR videos or photos. It also has Mini LED backlighting, so deep and inky blacks are visible in dark rooms when working in HDR. While the Acer excels at most tasks, if you're looking for a monitor with more of a focus on USB connectivity, consider the Dell U2723QE. It has five USB-A and three USB-C ports, one of which you can use with its KVM switch. However, it doesn't handle reflections well, so it doesn't work as well in very bright environments, and it has far worse HDR performance.

While most USB-C monitors support DisplayPort Alt Mode, some have Thunderbolt, which is what Mac computers and some Intel-based laptops support. It has a few advantages over DisplayPort Alt Mode, like higher power delivery and bandwidth, but it isn't available on as many monitors. Regardless, if you're looking for a monitor with Thunderbolt support, check out the Dell U4025QW. It connects to your computer via a USB-C port that supports Thunderbolt 4. It's rated to provide up to 140W of power to your laptop and allows a 40Gbps rated speed.

This monitor has useful extra features like a Picture-by-Picture mode, which is great if you want to view images from two sources side by side. It offers enough space to multitask as it has a massive 40-inch screen with a 21:9 ultrawide aspect ratio and 5120x2160 resolution, producing sharp text. It also has a KVM switch that makes it easy to multitask with different computers. If you don't like the ultrawide format, consider the 27-inch Apple Studio Display, which supports Thunderbolt 3 but is more optimized to use with a Mac computer.

If you find the Acer Nitro XV275K P3biipruzx a bit out of your price range or don't need Thunderbolt and its gaming or HDR performance, check out the ASUS ProArt Display PA279CRV. Like the Acer, its main USB-C port delivers 90W of power. It also has a 4k resolution, resulting in extremely sharp text, and its 27-inch screen is big enough to open two windows side by side. It's meant for content creation as it has a remarkably accurate sRGB mode and other picture modes for various color spaces you may need to work with.

However, its performance for most uses is worse than that of the Acer. It doesn't get as bright, though it's still quite capable of overcoming most glare. It also doesn't perform as well with HDR content, but this is what you have to expect with a less expensive monitor. The ASUS does have three USB-A ports, while the Acer only has two, so you can connect more devices.

If you find the ASUS ProArt Display PA279CRV too expensive, consider a cheaper monitor like the Dell S2722QC, which often goes on sale too. It has a smaller USB hub than the ASUS, as it has two USB-A ports and a single USB-C port, which is the main trade-off for getting something cheaper. It supports DisplayPort Alt Mode and power delivery of up to 65W, which is still enough power to charge smaller laptops but isn't enough to charge power-hungry laptops.

It's good for productivity as it has Picture-in-Picture and Picture-by-Picture modes, which is great if you want to connect two sources. It's also a great choice if you need to use it in a well-lit office space, as it has good reflection handling and is bright enough to overcome glare. Lastly, it has wide viewing angles and excellent ergonomics, so you can easily adjust the screen to an ideal viewing position and show content to someone next to you.

While you can find the Dell S2722QC at a budget-friendly price when it goes on sale, the ASUS ProArt Display PA278CV is another good option if you're on a budget and find the Dell slightly out of your price range. The main trade-off is that it has a lower 1440p resolution than the Dell, but while it has lower pixel density, the text clarity is still decent. Luckily, its USB-C port supports DisplayPort Alt Mode and 65W of power delivery, so you can easily connect a smaller laptop to display an image and charge it using a single cable.

Despite its low cost, it still has a few extra features, like its outstanding ergonomics that make it easy to adjust and a dedicated sRGB mode. This results in exceptional accuracy before calibration, as colors are accurate. Unfortunately, it doesn't support HDR, which is disappointing if you need that for video editing. If that's important to you, the Gigabyte M27Q P is another budget option that supports HDR, but its USB-C port is limited to 18W of power delivery, which isn't enough to charge laptops.

Jun 05, 2024: Replaced the LG 40WP95C-W with the Dell U4025QW as 'Best Thunderbolt,' as it has better performance and more features. Renamed 'Best Upper Mid-Range' to 'Best Mid-Range' and 'Best Mid-Range' to 'Best Lower Mid-Range' for better consistency with other recommendations. Replaced the LG 38WN95C-W with the LG 40WP95C-W as a Notable Mention.

Oct 12, 2023: Removed the Apple Studio Display as 'Best Monitor For Mac' because it doesn't fit into the scope of the article; renamed the Dell S2722QC to 'Best Mid-Range' to better reflect its market position; added the Gigabyte M32U to Notable Mentions.

Im trying to connect a 3rd monitor to my laptop through the usb c port. I already have a hp 24w monitor connected through the hdmi port, and have bought a QGeem usb c to hdmi adaptor to connect a 2nd hp 24w monitor but it does not register that its even plugged in, the monitor just stays dark and says input signal not found. i don't no wear the problem is, ive read my laptop has the correct graphics to support a 3rd screen. ive gone into the display settings and usb settings but its not even showing there's anything plugged in so im a bit stuck.

I am trying to connect two external monitors to my Spectre via the two USB-C ports. Both external monitors work fine, when connected to either of the Spectre USB-C ports, but only one at a time. When I connect both monitors at the same time, only one monitor (the first connected) works.

The laptop and S270n monitor also have an HDMI port but my preference is to connect to the S270n via USB-C, as this means I can use just one power supply (the S270n one) to also power the laptop (thus reducing desk clutter). The S14 monitor only has a single USB-C port (nothing else) for both power supply and video signal.

So my ideal set-up would be to connect S270n monitor to one of the Spectre USB-C ports (to supply power to the laptop and receive video signal from it) and connect the S14 monitor to the other Spectre USB-C port (to supply power and video signal from the laptop to the S14 monitor).

Both monitors work, from either of the laptop USB-C ports, if only one of the monitors is connected. So both laptop USB-C ports are capable of video transmission. But I cannot get both monitors to work simultaneously, regardless of which monitor is connected to which laptop USB-C port.
