ViewSonic Ultrawide ViewSonic VG3457CV 34" 1440p Ultrawide Curved Review
The ViewSonic VG3457CV packs a 5MP webcam and 100W USB-C into a 34-inch curved screen. It's a productivity powerhouse, but is its average performance a dealbreaker?
The 30-Second Version
This is a productivity-focused ultrawide with elite connectivity (96th percentile) and great ergonomics. Its 100Hz performance is just average, but the built-in 5MP webcam and 100W USB-C docking are huge conveniences. Buy it to clean up your home office, not to win esports tournaments.
Overview
The ViewSonic VG3457CV is a 34-inch ultrawide built for a desk, not a backpack. It scores a 78/100 for office use in our database, thanks to a feature set that's squarely aimed at productivity and video calls. You're getting a 3440x1440 curved VA panel, a pop-up 5MP webcam, and a USB-C port that delivers 100W of power to your laptop.
Right away, the numbers tell a story of extremes. Its connectivity lands in the 96th percentile, which is huge for a monitor. It's also in the 88th percentile for ergonomics, meaning you can adjust it just about any way you want. But its raw performance score is smack in the middle at the 50th percentile. That 100Hz refresh rate is fine, but it's not built to be a gaming or creative powerhouse.
Performance
Let's be clear: this isn't a speed demon. The 100Hz refresh rate and 5ms response time put its performance score right at the median for monitors we track. For office work and video, that's perfectly adequate. You won't see much ghosting in spreadsheets, but competitive gamers should look elsewhere.
Where it shines is in the details that make a workday easier. That 100W USB-C port is a one-cable solution for power, video, and data. The 5MP pop-up webcam is a legit upgrade over most built-in laptop cams, and the 350-nit brightness is bright enough for most well-lit rooms. The 1500R curve on the 34-inch screen helps keep everything in your peripheral vision without being too aggressive.
Pros & Cons

Cons
- Raw performance is merely average (50th percentile), capped at 100Hz. 10th
- It's a heavyweight at 9.5kg (21 lbs), so moving it is a two-person job.
- The 350-nit brightness, while fine for offices, isn't ideal for very bright rooms.
- VA panel viewing angles, while good, aren't as consistent as IPS for color-critical work.
- The price spread is wild, ranging from $630 to over $1400 depending on the vendor.

Value & Pricing
The value proposition here is entirely about features over frame rates. If you need a webcam, a dock, and a big curved screen for under a grand, this monitor makes a strong case. Just be smart about where you buy. We're seeing a price range from $630 to $1444 across different retailers. At the lower end of that spread, it's a compelling package. At the high end, you're paying a massive premium for the same hardware.
vs Competition
Stacked against other ultrawides, the VG3457CV carves its own niche. It's not competing with the Samsung Odyssey G9 on refresh rate or the ASUS ROG Swift on OLED contrast. Instead, it's going after the Dell UltraSharp crowd with better built-in features. Compared to a standard 34-inch business monitor, you're trading some color accuracy (it's in the 85th percentile for color) for the convenience of the pop-up cam and the 100W USB-C. For a pure productivity setup, those features can be worth more than a higher refresh rate.

Common Questions
Q: Is the USB-C port Thunderbolt?
Yes, the spec sheet lists it as a USB-C port with Thunderbolt connectivity. This supports the 100W power delivery, video output, and data transfer all through one cable.
Q: Is this monitor good for gaming?
It's okay for casual gaming. With a 100Hz refresh rate (50th percentile for performance), it's smoother than 60Hz but far from the 144Hz+ standard for serious gaming. The 5ms response time is decent but not competitive-grade.
Q: Does the webcam support Windows Hello?
Yes, the manufacturer description states the 5MP pop-up IR webcam is Windows Hello compatible, allowing for facial recognition login.
Who Should Skip This
Hardcore gamers and professional color graders should look elsewhere. The 100Hz refresh rate and 50th percentile performance score mean you're leaving a lot of frames on the table compared to dedicated gaming monitors. Similarly, while its color score is good (85th percentile), professionals needing absolute color accuracy for print or video work will want a monitor with factory calibration and an IPS panel for better viewing angle consistency.
Verdict
We'd recommend the ViewSonic VG3457CV to hybrid workers and office users who want to simplify their desk setup. The combination of the webcam, the powerful USB-C port, and the adjustable stand solves real problems. Just don't buy it for gaming or color-critical video editing. Its performance is fine, not fantastic. Shop around for that sub-$700 price, and it becomes a very smart buy for what it is.
