The 7 Best Ultrawide Monitors With USB-C for a One-Cable Desk, Ranked & Reviewed

Our verdict: A 34 inch IPS with Thunderbolt 4, ten USB 3.2 Gen2 ports and Ethernet in one box.

The U3425WE is a 34 inch IPS ultrawide at 3440x1440 and 120Hz. It is the only Thunderbolt 4 monitor in this ranking, with ten USB 3.2 Gen2 ports in total, Ethernet, picture-by-picture, an ambient light sensor and G-Sync compatibility, under a 3-year warranty.

It wins because it turns the monitor into a proper dock. Thunderbolt 4 carries video, data and power through one cable, and the port count lets a laptop plug into a keyboard, drives and a network without a separate hub. IPS panels also hold their colors from the side better than the VA panels used by most rivals here. The price is the catch: it sits in the $500 and up bracket, and some of that cost pays for features a simple home setup will not touch.

Buy it if you work from one laptop and want a single-cable desk that lasts. Skip it if you do not need Thunderbolt or this many ports.

Our verdict: A 49 inch, 5120x1440 IPS Black monitor with 90W USB-C, KVM and 2.5GbE.

The U4924DW is a 49 inch IPS Black monitor at 5120x1440, the widest panel here. It has 90W USB-C power delivery, an automatic KVM switch, 2.5GbE Ethernet, 11 USB ports in total, dual 9W speakers and 100% sRGB coverage.

It ranks second because a 49 inch screen is effectively two 27 inch panels without a bezel in the middle, which suits traders, coders and anyone who wants side-by-side documents. The automatic KVM lets one keyboard and mouse control two computers, a feature the 34 inch Dell lacks. The cost is desk space and money: a 49 inch curve needs a deep, wide desk, and the price lands in the $500 and up bracket. At 1440 pixels tall it also has the same vertical resolution as the 34 inch models.

Buy it if you want the ultimate wide workspace and have the desk. Skip it if your desk is under about 55 inches wide.

Our verdict: The only 34 inch pick with a built-in KVM switch, plus 95W USB-C and Gigabit Ethernet.

The Philips 346B1C is a 34 inch VA ultrawide at 3440x1440 and 100Hz. It has 95W USB-C power delivery, a built-in KVM switch, a Gigabit Ethernet port, 119% sRGB and 90% Adobe RGB coverage, and a 4-year advance replacement warranty.

It takes third place because it hands you the strongest charging in the group at 95W while including a KVM in the $200 to $500 bracket. If you share a keyboard and mouse between a work laptop and a personal PC, the KVM saves you a switch box. The 4-year advance replacement warranty is the best coverage here, because a replacement ships before you send yours back. The tradeoff against the IPS Dells is the VA panel, which has deeper blacks but narrower viewing angles.

It is a strong buy for hybrid workers juggling two computers. Skip it if you want an IPS panel or Thunderbolt.

Our verdict: A 1000R curved 34 inch with 90W USB-C, Ethernet and HDR10 for a mid-range price.

The ViewFinity S65UA is a 34 inch, 1000R curved VA monitor at 3440x1440 and 100Hz. It provides 90W USB-C power delivery, HDR10 support, a built-in Ethernet port, TUV-certified eye care and a 3-year warranty.

It places fourth because it gives you 90W charging, a strong figure that covers most large laptops, plus Ethernet in the $200 to $500 bracket. The 1000R curve is the tightest of the group and wraps around your field of view, which many users like for immersion and some find a bit much for spreadsheets. HDR10 is a label more than a showpiece on a VA panel without local dimming. It lacks the KVM of the Philips and the speed of the Dell S3425DW.

Buy it if your laptop wants 90W and you like a strong curve. Skip it if you want a KVM.

Our verdict: A 34 inch curved VA with up to 120Hz, 0.03ms response and 65W USB-C.

The S3425DW is a 34 inch curved VA monitor at 3440x1440 and up to 120Hz. It lists a 0.03ms response time, the fastest here, with 65W USB-C power delivery, 99% sRGB, 95% DCI-P3 and 3000:1 contrast. It has built-in speakers and Dell's Premium Panel warranty.

It ranks fifth because speed and color are strong, but the 65W USB-C limits it for large laptops, and it has no Ethernet or KVM. For an ultrabook that draws well under 65W, that is fine. The 120Hz refresh gives smoother scrolling and gaming than the 100Hz rivals, and the 95% DCI-P3 coverage suits photo and video work. The 3000:1 contrast is the VA advantage, with deeper blacks than IPS in a dim room.

Buy it for mixed work and play with a light laptop. Skip it if you need more than 65W.

Our verdict: A 34 inch curved VA with a 5MP Windows Hello webcam, mic and a 4-year warranty.

The Philips 34E1C5600HE is a 34 inch curved VA monitor at 3440x1440 and 100Hz. It has 65W USB-C power delivery, a built-in 5MP webcam with Windows Hello and a noise-canceling mic, dual 5W speakers and a 4-year advance replacement warranty.

It ranks sixth because the webcam is its identity. For video calls it removes the need for a separate camera, and Windows Hello gives you face login without extra hardware. The other tradeoff is power delivery: 65W suits lighter laptops only. It has no KVM or Ethernet port. A monitor webcam sits at the top of the screen, which gives a flattering call angle, but it is hard to replace if it fails, so the long warranty matters.

Buy it if you spend your day on video calls. Skip it if you already own a good webcam.

Our verdict: A 34 inch curved VA with 65W USB-C, Reader Mode, PbP and a height-adjustable stand.

The LG 34WR55QK-B is a 34 inch curved VA monitor at 3440x1440 and 100Hz. It supports 65W USB-C power delivery, Reader Mode, picture-by-picture, OnScreen Control software and a stand with height and tilt adjustment.

It ranks last because the spec sheet stops at the basics: no KVM, no Ethernet, no stated warranty detail and only 65W of charging. That does not make it a poor monitor; it makes it the plainest. Reader Mode softens the display's blue light, and OnScreen Control lets you split windows with a few clicks. A height-adjustable stand is a real convenience that some rivals leave out.

Buy it if you want the simplest USB-C ultrawide and a clean setup. Skip it if you need docking features.
