The LG 35WN65C-B is a 35-inch curved ultrawide display that LG released in 2020. It's available at Costco as the LG 35WN65C-B.AUS, and it sits alongside the LG 35WN75C-B, which is essentially the same monitor but with USB-C input. It focuses on office features as its 21:9 aspect ratio offers plenty of screen space to open multiple windows at once. However, it's limited on other features like an ergonomic stand and an sRGB mode for color accuracy. While there aren't many features built-in, LG offers programs you can download to improve your workflow. It supports OnScreen Control to help place those windows in a position you like and Dual Controller, which acts as a KVM switch so that you can control two sources with the same keyboard and mouse, but it doesn't work on macOS.
Our Verdict
The LG 35WN65C-B is a decent monitor for most usages. It's decent for office use and good for content creation because it has a large screen that offers plenty of space for multitasking, the text clarity is good, and it has decent out-of-the-box accuracy. However, it has limited ergonomics and narrow viewing angles, so it isn't the best for sharing your work with others and doesn't get bright. It's also decent for gaming as it has a few gaming features like variable refresh rate (VRR) support and low input lag, but it has bad motion handling. Lastly, it's decent for SDR media consumption as it displays deep blacks, but it doesn't get bright enough to make highlights pop for a satisfying HDR experience.
- Large ultrawide screen.
- Good text clarity.
- Good for moderately-lit rooms.
- Great native contrast.
- Struggles in bright environments.
- Narrow viewing angles.
- Limited ergonomics.
- Bad motion handling.
The LG 35WN65C is decent for office use. The 35-inch screen is great for multitasking as you can easily open multiple windows at once, and the 3440x1440 resolution results in clear text. It looks good if you're sitting directly in front, but it isn't ideal for sharing your screen with others as it doesn't offer any swivel adjustments and has narrow viewing angles. While it performs well in rooms with a few lights around, it doesn't get bright enough to fight a ton of glare either.
- Large ultrawide screen.
- Good text clarity.
- Good for moderately-lit rooms.
- Two USB 3.0 ports.
- Struggles in bright environments.
- Narrow viewing angles.
- Limited ergonomics.
The LG 35WN65C-B is decent for gaming. It's a good choice for dark room gaming as it displays deep blacks but doesn't have a local dimming feature to further improve it. It has a 100Hz refresh rate with variable refresh rate support to reduce screen tearing and has low input lag for a responsive feel. Unfortunately, motion looks bad, as it has a slow response time that results in black smearing and some inverse ghosting.
- FreeSync VRR and G-SYNC compatibility.
- Low input lag.
- Great native contrast.
- Bad motion handling.
- Limited to 100Hz refresh rate.
- No local dimming feature.
The LG 35WN65C is decent for watching multimedia content. The 21:9 aspect ratio is ideal for watching widescreen movies, and it looks great in dark rooms thanks to its high native contrast ratio, but it doesn't have a local dimming feature. Unfortunately, it isn't the best for watching content with friends because it has narrow viewing angles that make the image look washed out from the sides, and it has limited ergonomics, meaning the screen is hard to adjust.
- Large ultrawide screen.
- Good for moderately-lit rooms.
- Great native contrast.
- Narrow viewing angles.
- Limited ergonomics.
- No local dimming feature.
The LG 35WN65C-B is good for content creation. The large screen and ultrawide format allow you to open multiple windows at once or view more of your video timeline without scrolling too much. It also has decent out-of-the-box accuracy but lacks an sRGB mode to limit the colors to the sRGB color space. Unfortunately, it doesn't offer swivel adjustments and has narrow viewing angles, so it isn't ideal if you need to share your work with a coworker or client.
- Large ultrawide screen.
- Good text clarity.
- Good for moderately-lit rooms.
- Two USB 3.0 ports.
- Decent out-of-the-box accuracy.
- Struggles in bright environments.
- Narrow viewing angles.
- Limited ergonomics.
- No sRGB mode.
The LG 35WN65C is okay for HDR. It displays deep blacks in dark rooms and displays a wide range of colors in HDR, but it doesn't get bright enough to make them look vivid. It also doesn't have a local dimming feature to further improve the black levels or to make small highlights pop against the rest of the screen, so it doesn't deliver a satisfying HDR experience.
- Great native contrast.
- No local dimming feature.
- Doesn't get bright to make highlights pop.

Popular Monitor Comparisons
The LG 35WN65C-B is a decent budget-friendly ultrawide monitor with a few office-oriented features. It performs well for what it's meant for, but you can also find better ultrawides in the same price range, like the Dell S3422DWG.
See our recommendations for the best ultrawide monitors, the best curved monitors, and the best work monitors.
The Gigabyte G34WQC is a more versatile monitor than the LG 35WN65C-B. The Gigabyte is the better choice if you want to use it in a well-lit room as it gets much brighter, and if you also want to use it for gaming, it has a higher refresh rate and better motion handling. The Gigabyte also has a few extra features like a Picture-by-Picture mode built-in, but the LG has two USB ports, which the Gigabyte doesn't have.
The AOC CU34G2X is better overall than the LG 35WN65C-B. The AOC is mainly a better gaming monitor as it delivers better motion handling thanks to its higher refresh rate. Even if you want to use it for office use, the AOC has more USB ports and has Picture-by-Picture and Picture-in-Picture modes, which the LG only has if you download a driver.
The LG 38WN95C-W and the LG 35WN65C-B are both ultrawide office monitors, but they have a few differences. The 38WN95C-W has many more features like a USB-C input and a higher resolution with a bigger screen. It also gets much brighter, making it the better choice to use in a well-lit room. The 38WN95C-W also has wider viewing angles, making it ideal for sharing your screen with others as the image remains accurate from the sides.
The Acer Nitro XV340CK Pbmiipphzx is a better monitor overall than the LG 35WN65C-B. The Acer is more versatile for gaming as it has a higher refresh rate and better motion handling. It also has much better ergonomics and better viewing angles if you want to use it to share your screen with someone else. However, if you're placing your monitor in a dark room, the LG is the better choice as it displays deeper blacks.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
