The LG 34GP83A-B is a 34-inch, 1440p ultrawide gaming monitor with a maximum refresh rate of 160Hz. As a part of LG's UltraGear lineup it sits alongside other ultrawide monitors, like the similar but cheaper 34-inch LG 34GP63A-B, and the higher-end 34-inch OLED LG 34GS95QE-B. It competes with other 34-inch ultrawide monitors, like the Dell S3422DWG and the Gigabyte M34WQ. It has several additional features, such as a crosshair overlay to assist with aiming, a black stabilizer mode to help make objects more visible in dark scenes, and a reader mode to help reduce eye strain.
Our Verdict
The LG 34GP83A-B is decent for PC gaming. It has FreeSync and G-SYNC compatibility to reduce screen tearing, and its 160Hz max refresh rate is good enough for most gamers but not for competitive gaming. It has low input lag for a responsive feel and a fast response time, so fast-moving objects look crisp. However, its disappointing contrast causes deep blacks to appear gray in a dark room, and highlights don't pop in HDR.
- Fast response time at all refresh rates.
- Low input lag.
- Supports FreeSync and is G-SYNC compatible.
- Highlights don't pop.
- Low contrast makes blacks look gray in dark rooms.
The LG 34GP83A-B is okay for console gaming, but it has some limitations. It has a fairly fast response time at both 60Hz and 120Hz, so fast-moving objects look crisp. It also has low input lag for a responsive feel while gaming. However, it doesn't support VRR with the PS5. Additionally, with the Xbox Series X|S, you have to choose between having a 60Hz refresh rate with HDR and a downscaled image or a 120Hz refresh rate without HDR. It also has limited picture quality as blacks look gray in dark rooms, and highlights don't pop. Finally, the consoles don't support ultrawide gaming, so you'll see black bars on the sides.
- Fast response time at all refresh rates.
- Low input lag.
- Can't take full advantage of consoles.
- Highlights don't pop.
- Low contrast makes blacks look gray in dark rooms.
The LG 34GP83A-B is decent for office use. It has good text clarity, and its 34-inch screen allows you to open multiple windows at the same time. It also has very good brightness, but visibility is still an issue in a bright room due to its disappointing reflection handling. However, it doesn't swivel, so sharing your work with a colleague is more difficult.

Disappointing reflection handling.
The LG 34GP83A-B is decent for content creation. It has good text clarity, and you can open multiple windows at the same time due to its large 34-inch screen. Additionally, it has great color accuracy before calibration, and it displays a wide range of HDR colors, which is great if you're editing photos or videos in a wider color gamut. However, its disappointing contrast causes deep blacks to appear gray in a dark room, and highlights don't pop in HDR, so it's not good for editing HDR content. Additionally, it can't swivel, so sharing your screen with colleagues is more difficult.

Popular Monitor Comparisons
The LG UltraGear 34GP83A-B is decent for PC gaming, as fast-moving objects look fairly crisp and its ultrawide screen provides an immersive experience. However, it's not the best choice if you care about HDR image quality. Its highlights don't get bright enough to pop, and deep blacks appear gray in a darker room. It competes with much cheaper ultrawide monitors that have slightly worse motion handling but get brighter in HDR and have better contrast, such as the Dell S3422DWG. If you're willing to spend a bit more you can also get an ultrawide OLED with vastly better motion handling and image quality, such as the Dell Alienware AW3423DWF, and it's a much better choice for gaming if you can afford it.

The LG 34GP83A-B and the LG 34GN850-B are almost identical in design, features, and performance. The main differences are that the 34GN850-B has slightly better response time at max refresh rate, and it gets a bit brighter in HDR, although not by much.
The LG 34GP83A-B is better than the Dell Alienware AW3420DW for most uses. It has a higher 160Hz refresh rate compared to the Dell's 120Hz, and its response time is significantly better. Also, its higher peak brightness makes it more ideal for well-lit rooms, and it supports HDR. The Dell has better ergonomics because it allows for swivel adjustment, and it has more USB ports. In terms of VRR support, the LG is compatible with FreeSync and G-SYNC, while the Dell has native G-SYNC support and FreeSync compatibility.
The LG 34GP83A-B and the LG 34GP950G-B are pretty similar overall. The 34GP950G has slightly better reflection handling, and the unit we bought has better gray uniformity, but this can vary between units. The 34GP950G has a local dimming feature, but it's pretty bad, so this doesn't add much over the 34GP83A-B. Finally, there's a slight difference in the supported gaming technologies. The 34GP950G is a native G-SYNC monitor, whereas the 34GP83A-B is just G-SYNC compatible, so if you have an NVIDIA graphics card and want to get the most out of it, the 34GP950G might be the better choice.
The Gigabyte M34WQ is better than the LG 34GP83A-B. The Gigabyte has better ergonomics, much better reflection handling, and an optional backlight strobing feature. The Gigabyte is better for productivity as it has a few extra office features built-in, including a keyboard video and mouse switch (KVM), which allows you to switch between two sources with one set of input devices. On the other hand, the LG is better for some gamers as it has a faster response time.
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.
