The point of a USB-C ultrawide is a single cable: video, laptop charging and data over one connection, replacing a power brick, a video cable and a hub. How well that works depends on the details. Charging here ranges from 65W to 95W, and only some models add a KVM switch, Ethernet or Thunderbolt 4.
Start with your laptop's own charger rating. A monitor that supplies at least that wattage over USB-C should be able to charge it at full speed; a lower figure may only slow the battery drain under heavy load.
The seven monitors below include six 34-inch 3440 x 1440 models and one 49-inch 5120 x 1440 model. Our comparison is based on published specifications, ports and price position, not hands-on testing.

Best Low-Cost USB-C Ultrawide1 of 7
LG 34WR55QK-B on Amazon (opens in a new tab)
The LG 34WR55QK-B is the least expensive way into a one-cable ultrawide: a 34-inch curved VA panel at 3440 x 1440 and 100Hz, with 65W USB-C charging, at the lowest price here at the time of writing.
Best for
- A thin-and-light laptop that needs one-cable video and charging for less.
Skip if
- Your laptop's charger is above 65W; the Samsung S65UA supplies 90W.
Why we like it
It adds a Reader Mode that reduces blue light, picture-by-picture for two sources side by side, LG's OnScreen Control software and a stand that adjusts for height and tilt.
65W suits many thin-and-light laptops but may not keep up with a higher-power laptop under load. It has no KVM switch or Ethernet.
Key dimensions & specs
- Panel: 34" curved VA, 3440 x 1440, 100Hz
- USB-C charging: 65W

Best for
- Office work by day and casual gaming after hours.
Skip if
- You don't need 120Hz; the LG covers the same basics for less.
Why we like it
It has 65W USB-C charging and built-in speakers, and Dell's Premium Panel warranty covers bright-pixel defects.
It costs more than the LG for the same 65W charging, and there's no KVM or Ethernet. As a VA panel, viewing angles trail the IPS UltraSharp models.

Best for Higher-Power Laptops3 of 7
Samsung ViewFinity S65UA on Amazon (opens in a new tab)

Best for
- Higher-power laptops that need wired networking through the monitor.
Skip if
- You also run a second computer; the Philips 346B1C adds a KVM switch.

It costs more than the LG and Dell 34 Plus, and there's no KVM switch. A 1000R curve is pronounced; if you prefer a flatter screen, check the curvature of the alternatives.

- USB-C charging: 90W

Best for

Skip if

Best for
- A work laptop and a personal computer sharing one monitor, keyboard and mouse.
Skip if

Why we like it
Philips lists 119% sRGB and 90% Adobe RGB coverage on its 3440 x 1440, 100Hz curved VA panel, and a four-year advance replacement warranty.
If you only use one computer, the KVM adds cost you won't use, and it costs more than the Samsung S65UA.

Best for
- Thunderbolt laptops on a desk with many wired peripherals.
Skip if
- Your laptop has standard USB-C only; the Philips 346B1C offers 95W and a KVM for less.
Why we like it
Its IPS panel runs 3440 x 1440 at 120Hz, with picture-by-picture, an ambient light sensor and G-Sync compatibility. It has a three-year warranty.
Thunderbolt only helps if your laptop supports it, the listing summary doesn't give a charging wattage, and it costs well above the other 34-inch models at the time of writing.
Key dimensions & specs

- USB-C charging: 90W
- KVM: automatic
- Ethernet: 2.5GbE

What to Look for in an Ultrawide Monitor with USB-C
Key buying criteria so you get the right fit the first time.
Match charging wattage to your laptop
Check your laptop charger's wattage. Models here supply 65W (LG, Dell 34 Plus, Philips 34E1C5600HE), 90W (Samsung, Dell U4924DW) or 95W (Philips 346B1C).
Decide on docking features
A KVM switch shares one keyboard and mouse between two computers; Ethernet adds wired networking; Thunderbolt 4 adds bandwidth for compatible laptops.
Choose panel type and refresh rate
VA panels here offer high contrast at lower prices; the UltraSharp models use IPS. Refresh rates run from 100Hz to 120Hz.
Size it to your desk
A 34-inch ultrawide suits most desks; the 49-inch Dell needs noticeably more width and depth.

Frequently Asked Questions
What does USB-C Power Delivery do on a monitor?
It lets one cable carry video and data while charging your laptop. The wattage decides how fast it can charge.
Is 65W enough?
It depends on your laptop. If your laptop's own charger is 65W or less, a 65W monitor should keep up. If it's higher, consider a 90W or 95W model.
34-inch or 49-inch?
A 34-inch 3440 x 1440 and a 49-inch 5120 x 1440 screen have similar pixel density; the 49-inch is simply wider. The decision is mostly about desk space and whether you want one screen in place of two.
Which monitors can run two computers?
The Philips 346B1C and the Dell U4924DW have built-in KVM switches.
Do I need Thunderbolt 4?
Only if your laptop supports it and you need its extra bandwidth for peripherals. Standard USB-C covers video, charging and data for many setups.
Bottom Line
For a single laptop, the LG 34WR55QK-B covers one-cable video and 65W charging for the least money; the Samsung S65UA steps up to 90W and Ethernet, and the Dell S3425DW adds 120Hz.
For two computers, the Philips 346B1C combines a KVM with 95W charging at 34 inches, and the Dell U4924DW does the same at 49 inches for far more. The UltraSharp U3425WE is for Thunderbolt laptops, and the Philips 34E1C5600HE for a built-in webcam.
