The 5 Best 34 Inch + Monitors - Winter 2021 Reviews

The Dell U3818DW is the best ultrawide monitor for office use we've tested. It's a massive 38 inch curved monitor that provides plenty of screen real estate so that you can place multiple windows side-by-side. To take advantage of its large screen size, it has a Picture-in-Picture/Picture-by-Picture mode that lets you display two input signals simultaneously, and you can control both devices with one set of peripherals using its integrated KVM switch.

It has full sRGB coverage and good Adobe RGB coverage, making it a good choice for content creators working in the SDR color space. Accuracy is excellent out of the box, which means that you might not need to calibrate it, saving you time and money. It has wide viewing angles to maintain image accuracy when viewing off-center, and the stand allows for height, tilt, and swivel adjustments. It doesn't handle reflections all that well and only gets decently bright, so glare might be an issue in well-lit, sunny rooms.

Unfortunately, the response time is bad, so it's not the best option if you want to game on the side. Also, it doesn't support HDR. It has speakers built-in if you don't have dedicated ones, and the backlight is entirely flicker-free to help reduce eye strain. Overall, it's a good, feature-rich ultrawide monitor that should satisfy most people, and even though it was first released in 2018, it's still one of the best 38 inch monitors we've tested.

The best large monitor that we've tested is the LG OLED48CXPUB. At 48 inches, it packs a lot of screen space, making it easy to open multiple windows at once. This is a TV that we've tested as a monitor, and it provides great all-around performance. You can read about the TV review here, but the monitor and TV results aren't comparable because of the different ways we test each.

This TV is different from ultrawide monitors because it maintains the 16:9 aspect ratio, so you won't get any black bars on the size when gaming or viewing content in full-screen mode. It has an OLED panel that delivers a near-instant response time, so fast-moving content looks smooth. It doesn't get bright enough to combat a ton of glare, but it has outstanding reflection handling if you want to use it in a well-lit room. OLEDs can individually turn off pixels, resulting in perfect blacks, making it ideal if you work in a dark room. Also, it has wide viewing angles, so the edges of the screen remain accurate if you sit close.

Unfortunately, the main downside to using an OLED is the risk of permanent burn-in. This happens with constant exposure to static elements, like a computer's user interface, so we suggest using it for varied content. If you want to use it for gaming, it has a 120Hz panel, VRR support, and HDMI 2.1 support. If you're in the market for the best large monitor, you should be pleased with this one.

The best 49 inch monitor we've tested is the Samsung Odyssey G9. Mainly designed for gaming, this super ultrawide offers good all-around performance. It has a 5120x1440 resolution and 32:9 aspect ratio, which is the equivalent of placing two 27 inch, 1440p monitors side-by-side. It has an aggressively curved screen, which somewhat helps with the viewing angles, but you still may notice inaccurate colors at the edges.

It has an extremely high 240Hz refresh rate that results in a good response time. Surprisingly, its response time is even better at 60Hz, so motion looks smooth no matter what frame rate you're using. It has native FreeSync support and G-SYNC compatibility to reduce screen tearing, and the input lag is extremely low. It performs well in both bright and dark rooms as it has a decent contrast ratio that allows it to produce deep blacks, and it gets bright enough to combat glare. If you're a photo editor, it has great coverage of the Adobe RGB color space and has decent out-of-the-box color accuracy.

Unfortunately, its ergonomics are limited, which is expected for a screen of this size, and it has a narrow swivel and tilt range. It's well-built, but due to the aggressive curve, it's very thick, and you'll need a deep desk to place it on. On the upside, it provides a good HDR experience because it displays a wide color gamut and gets bright enough to make highlights pop. If you're looking for the best 49 inch monitor, you should be happy with this one.
