The LG 34GP83A-B is a great ultrawide gaming monitor. It has a large, curved screen that provides amazing immersion when gaming and tons of real estate for work. It has fast response time, low input lag, and you can overclock its 144Hz refresh rate up to 160Hz to deliver smoother and more responsive gameplay. Viewing angles are decent, fine for sharing content casually or co-op gaming; however, there's some loss of image accuracy when viewing from the side, so it might not be ideal if you need to share work that requires precision. Unfortunately, while it gets bright enough to overcome glare easily, it isn't enough to deliver a true HDR experience. Also, it has a low contrast ratio that makes blacks appear gray in the dark. On the upside, content creators should be happy to hear that it has full sRGB and excellent Adobe RGB coverage, superb gradient handling, and no color bleed.
The LG 34GP83A-B is a good monitor for most uses. It has low input lag, exceptional response time, and a high refresh rate, making it great for gaming. Its large, high-resolution screen delivers an immersive viewing experience for media consumption and provides plenty of space for work. While it supports HDR, it can't deliver a satisfying HDR experience because it has a low contrast ratio, no local dimming, and doesn't get bright enough to make highlights pop.
The LG 34GP83A-B is good for office use. It has a large screen that provides plenty of space for multitasking and a high resolution to render text clearly. There's some loss of image accuracy when viewing from the side; however, it should be fine for sharing documents or spreadsheets that don't require perfect image accuracy. Its reflection handling is just okay, but it gets bright enough to overcome glare. Unfortunately, the stand only allows for tilt and height adjustments.
The LG 34GP83A-B is a great gaming monitor. It has incredibly low input lag and exceptional response time, and its 144Hz refresh rate can be overclocked up to 160Hz for even more responsiveness. It's compatible with FreeSync and G-SYNC to deliver a nearly tear-free gaming experience. Its large, high-resolution screen feels immersive, which is great for playing atmospheric games like RPGs. Unfortunately, it's not the most ideal for gaming in the dark because it has a low contrast ratio that makes blacks appear gray.
The LG 34GP83A-B is good for media consumption. It has a large, high-resolution screen that delivers an immersive viewing experience. Viewing angles are decent, although there's still some loss of image accuracy when viewing off-center. It's well-suited for bright rooms because it overcomes glare easily, but it isn't ideal for dark rooms due to its low contrast ratio. Sadly, the stand only allows for height and tilt adjustments.
The LG 34GP83A-B is good for content creation. Its ultrawide format lets you open multiple windows side-by-side and makes it easier to lay out your timeline when editing videos. It has full sRGB and excellent Adobe RGB coverage, superb gradient handling, and no color bleed. The viewing angles are only decent, so it's not the best for sharing work that requires the highest accuracy. Its reflection handling is just okay, but it gets bright enough to fight glare.
The LG 34GP83A-B is decent for gaming in HDR. It has low input lag, fast response time, and a high refresh rate to deliver a smooth gaming experience. However, the overall HDR experience is just okay because it has a low contrast ratio, no local dimming, and it doesn't get bright enough to make highlights stand out. Also, enabling HDR limits the refresh rate to 144Hz.
The LG 34GP83A-B 34 inch ultrawide gaming monitor looks nearly identical to other monitors in the UltraGear lineup, like the LG 34GN850-B. It has thin borders on all sides and a wide V-shaped stand. The back is plain, except for the red accent ring around the inputs.
The stand is wide and deep; however, the feet are fairly thin, so you can still use the space between them to put other things. It supports the monitor well, and there's very little wobble.
The LG 34GP83A-B has poor ergonomics. It only allows for height and tilt adjustments.
Like most LG UltraGear monitors, the back is plain except for the red ring and logo. There's a quick-release feature to remove the stand for VESA-mounting, and the small hook in the middle of the stand is for cable management.
Both the screen and the stand are quite thick, so you need a deep desk to put it on.
The LG 34GP83A-B's build quality is decent, almost identical to the LG 34GN850-B. Although it's all plastic, it feels sturdy, and the stand supports the screen well. It doesn't feel particularly premium, but there are no obvious gaps in the construction. That said, the cable management hook feels pretty flimsy.
The LG 34GP83A-B has a sub-par contrast ratio, slightly lower than the advertised 1000:1 contrast. This makes blacks look grayish in dark rooms. Note that the contrast ratio can vary between individual units.
The LG 34GP83A-B 34 inch gaming monitor doesn't have a local dimming feature. The video above is provided for reference only.
The LG 34GP83A-B has great peak brightness in SDR, close to the advertised 400 cd/m². It's very consistent when displaying different content, and it's bright enough to overcome glare in most lighting conditions.
We measured the SDR peak brightness after calibration in the 'Gamer 1' Picture Mode with Brightness set to max.
The HDR peak brightness is okay, close enough to meet the 400 cd/m² requirement for its DisplayHDR 400 certification. It can bring out some highlights in games, especially if you game in a dark environment, but it's not enough for a true cinematic HDR experience.
We measured the HDR peak brightness in the 'Gamer 2' Picture Mode with HDR enabled and Brightness set to max.
The LG 34GP83A-B has decent horizontal viewing angles. Black level and gamma change much quicker when moving to the right than to the left. It should be fine for co-op gaming or sharing content casually, but it might bother professionals who need perfect image accuracy.
Decent vertical viewing angles. Images remain relatively accurate even if you mount the screen above eye level.
Impressive gray uniformity. There's some darkening around the edges, particularly at the top corners, but there's almost no dirty screen effect in the center. Uniformity is much better in near-dark scenes. Note that gray uniformity varies between units due to manufacturing tolerances.
Black uniformity is mediocre. There's visible backlight bleed along the top and bottom edges, as well as some clouding throughout the screen. The photo above doesn't show the entire screen due to the monitor's aspect ratio and the photo's crop. Uniformity is significantly worse at the bottom corners, which you can see in this photo. Note that black uniformity varies between units.
The LG 34GP83A-B has great accuracy out of the box. Most colors and shades of gray are only slightly inaccurate and hard to spot. The color temperature is warmer than our 6500K target, resulting in a reddish tint. Gamma doesn't follow the sRGB curve all that well; most scenes appear brighter than they should. We used the dedicated sRGB mode for testing; however, enabling this mode locks the Contrast, RGB, and Gamma settings. Note that accuracy varies between individual units.
Accuracy is superb after calibration. The remaining color inaccuracies aren't visible to the naked eye, and white balance is nearly perfect. The color temperature is much closer to our 6500K target, just a tad on the cooler side. Gamma is much better; however, some dark and bright scenes are still slightly too bright.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit due to manufacturing tolerances, even for the same model.
The LG 34GP83A-B has an exceptional SDR color gamut. It covers the entire sRGB color space used in most content and has excellent Adobe RGB coverage, which is mostly used for photo editing.
Exceptional SDR color volume. It only has trouble displaying dark colors due to its low contrast ratio.
The LG 34GP83A-B has a good HDR color gamut. It has good coverage of the DCI P3 color space used in most HDR content, and its coverage of the wider Rec. 2020 is decent.
Note: The DCI P3 coverage is much lower than the advertised 98% coverage. This is normal and is due to the way we measure DCI P3. We measure it by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors to the DCI P3 primaries. This results in a lower but arguably more accurate measurement.
Good HDR color volume. It has difficulty producing dark colors because it has a low contrast ratio, and it also has trouble with bright blues and greens.
The LG 34GP83A-B doesn't show any sign of image retention after displaying a high-contrast image for ten minutes. However, this varies between individual units.
Superb gradient handling. You shouldn't see any banding in most content. Setting the color depth to 10-bit limits the refresh rate to 144Hz.
There's no color bleed on the LG 34GP83A-B.
The reflection handling is okay. You might have some issues with glare if there's sunlight, but the screen gets bright enough to compensate.
Text clarity is good. Windows ClearType (top photo) makes the letters appear bolder, especially diagonal lines like on the R and N. However, it also makes vertical lines look slightly thinner, like on the T and I.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The LG 34GP83A-B has exceptional response time at its max refresh rate. Motion looks clear, and there's almost no blur trail behind fast-moving objects. The best overdrive setting is 'Fast' because it provides the fastest response time while keeping overshoot at an acceptable level.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The LG 34GP83A-B's response time at 60Hz is outstanding. Although the image isn't as clear as at max refresh rate, there's still little to no blur trail. The best overdrive setting at 60Hz is 'Normal' because 'Off' is slower, and there's too much overshoot with the 'Fast' and 'Faster' options. This means that you might have to change the overdrive setting if your in-game frame rate drops.
The backlight is entirely flicker-free, which helps minimize image duplication and reduce eye strain.
The LG 34GP83A-B 34 inch gaming monitor doesn't have Black Frame Insertion feature.
The LG 34GP83A-B's 144Hz refresh rate can be overclocked up to 160Hz; however, it's only possible over a DisplayPort connection, and Adaptive Sync must be enabled in the monitor's OSD settings. Over HDMI, the refresh rate is limited to 85Hz, and FreeSync only works between 48Hz and 85Hz. G-SYNC only works over DisplayPort.
We noticed that FreeSync is a bit unstable over HDMI and requires many attempts to get it working. Also, it doesn't seem like there's any LFC (Low Frame Compensation) when using HDMI.
The LG 34GP83A-B has exceptionally low input lag to provide incredibly responsive gameplay. We don't have a measurement for HDR input lag because we lack the necessary tools to measure input lag with HDR over a DisplayPort connection, and we can only achieve a maximum refresh rate of 50Hz at 10-bit over HDMI. That said, we don't expect any noticeable increase in latency when in HDR. The maximum refresh rate at 10-bit over DisplayPort is 144Hz.
The LG 34GP83A has a large, high-resolution screen that delivers an immersive gaming experience and provides tons of screen space for multitasking. However, keep in mind that not all games support an ultrawide format, so you might see black bars at the sides, or the image might be stretched to fill the screen.
The LG 34GP83A has a few additional features, including:
There's a single joystick below the LG branding in the center of the bottom bezel. You can use it to turn the monitor On/Off and navigate the on-screen menu.
