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.

How We Test Monitors

We buy and test more than 30 monitors each year, with units that we buy completely on our own, without any 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 and custom tools to measure various aspects with objective data-based results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance against the competition, and whether or not it's easy to find.

Our Verdict

7.1
PC Gaming 

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.

Pros
  • Fast response time at all refresh rates.
  • Low input lag.
  • Supports FreeSync and is G-SYNC compatible.
Cons
  • Highlights don't pop.
  • Low contrast makes blacks look gray in dark rooms.
6.5
Console Gaming 

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.

Pros
  • Fast response time at all refresh rates.
  • Low input lag.
Cons
  • Can't take full advantage of consoles.
  • Highlights don't pop.
  • Low contrast makes blacks look gray in dark rooms.
7.3
Office 

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.

Pros
  • Bright enough to fight glare in some environments.

  • Good text and image clarity.
Cons
  • Doesn't swivel.
  • Disappointing reflection handling.

7.3
Editing 

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.

Pros
  • Bright enough to fight glare in some environments.

  • Good text and image clarity.
  • Accurate before calibration.
Cons
  • Doesn't swivel.
  • Disappointing reflection handling.

7.3
Brightness 

The LG 34GP83A-B has decent brightness. While it's bright enough to fight glare in some environments, it doesn't overcome the brightest glare. It also doesn't make highlights pop in HDR.

Pros
  • Bright enough to fight glare in some environments.

Cons
  • Highlights don't pop.
7.7
Response Time 

The LG 34GP83A-B has a good response time at all refresh rates.

Pros
  • Fast response time at all refresh rates.
Cons
None
5.1
HDR Picture 

The LG 34GP83A-B is disappointing for HDR. It has a low contrast ratio, so blacks look gray in dark rooms, and it lacks a local dimming feature.

Pros
None
Cons
  • Low contrast makes blacks look gray in dark rooms.
  • Lack of local dimming feature.
6.7
SDR Picture 

The LG UltraGear 34GP83A-B has okay picture quality in SDR. Its main strength is that it displays a wide range of colors, but blacks look gray in dark rooms due to its low contrast.

Pros
None
Cons
  • Low contrast makes blacks look gray in dark rooms.
8.7
Color Accuracy 

The LG 34GP83A-B has great color accuracy. While it has an accurate sRGB mode, it only has decent gray uniformity and the edges of the screen look darker than the center.

Pros
  • Accurate before calibration.
  • Decent gray uniformity.

    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.

    For more options, check out our recommendations for the best gaming monitors, the best ultrawide gaming monitors, and the best 34-49 inch monitors.

    Dell S3422DWG

    The LG 34GP83A-B and the Dell S3422DWG use different panel technologies, each with strengths and weaknesses. The LG's IPS panel delivers much better viewing angles, and it has a faster response time. The VA panel on the Dell delivers much better black uniformity and better contrast. 

    Dell Alienware AW3420DW

    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.

    Dell Alienware AW3425DWM

    The LG 34GP83A-B and the Dell Alienware AW3425DWM are both ultrawide gaming monitors, with a few differences, mainly due to their panel types. The LG has an IPS panel with wider viewing angles and less smearing with fast-moving objects, so it's a better choice for playing action games with someone next to you. However, the Dell monitor has an advantage with picture quality, as its VA panel has a higher contrast ratio for deeper blacks. The Dell is also the better choice for gaming in well-lit rooms, as it gets brighter, too.

    LG 34GN850-B

    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.

    This LG UltraGear 34GP83A-B has a gamer-oriented design with a black plastic body. Though the monitor has a simple aesthetic from the front, both the appearance of the tripod-based stand and the back of the monitor make it clear this is a gaming monitor.

    Build Quality

    The build quality is satisfactory. Though it has a basic plastic build it's fairly sturdy. However, the cable management slot at the back feels a bit flimsy.

    The ergonomics are mediocre. It has great height adjustment so you can set it to your preferred position for a long gaming session. However, it can't swivel, so it's more difficult to share your screen with another person while co-op gaming or working. The stand features a clip for cable management.

    The accuracy before calibration is excellent. It clamps colors to the sRGB color space well, and though it slightly oversaturates most colors it has great color accuracy. Additionally, the color temperature is very close to the 6500K target, and the white balance is very good. However, the gamma is slightly off, as most parts of scenes are a bit too bright.

    The refresh rate compliance is good. Although its response time isn't fast enough to make full color transitions before the monitor draws the next frame at its max refresh rate and at 120Hz, it's better at 60Hz.

    The CAD at the max refresh rate is good, but there's still some motion blur. The 'Normal' and 'Fast' overdrive settings have a similar total response time, but 'Fast' has less motion blur, while the 'Faster' setting has too much inverse ghosting.

    You need to use the console's HDMI override to get 1440p @ 60Hz. This isn't required with any other combination of resolution and refresh rate. The Xbox doesn't support HDR with 1440p or 1080p signals, so this isn't a limitation of the monitor. However, because the console doesn't support ultrawide signals, you'll see black bars on the sides unless you stretch the image.

    macOS Compatibility

    The LG 34GP83A works well with macOS. VRR only works up to 144Hz, so if you want to use the overclockable 160Hz, you need to use a fixed refresh rate instead. There aren't any noticeable issues with VRR in the desktop and games, except there's a thin gray bar at the top of the screen in games. When using a MacBook windows return to their original position when you wake the laptop up from sleep or open the lid.
