LG 34GP83A-B Monitor Review

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 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 disappointing 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.

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.

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.

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.

This monitor has some decent gray uniformity. There's some darkening around the edges, particularly at the top corners, but there's minimal dirty screen effect in the center.

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 excellent accuracy before calibration. It has an sRGB mode that locks the colors to the sRGB color space so that they don't look oversaturated, and the white balance is also great. The color temperature is close to the 6500K target, and gamma follows the target well for the most part, but most scenes are too bright. Also, using the sRGB mode locks out a few picture settings, including the Response Time, Black Stabilizer, and Color Temp, so if you want more customizable settings, you'll need to use a picture mode that's less accurate.

The accuracy is superb after calibration. The remaining color inaccuracies aren't visible to the naked eye, and the white balance is nearly perfect. Gamma is much better; however, some dark and bright scenes are slightly too bright.

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 an amazing HDR color gamut. It has fantastic coverage of the DCI-P3 color space used in most HDR content, but its coverage of the wider Rec. 2020 is limited.

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 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.

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.

You can use this monitor's overclock feature only when you have VRR enabled, and due to bandwidth limitations, the max refresh rate is limited over HDMI.

This monitor has native FreeSync support that works over DisplayPort and HDMI, but over HDMI, it only works from 48 to 85Hz, and the connection is unstable at times. Its G-SYNC compatibility only works over DisplayPort too. If you're looking for a monitor that natively supports G-SYNC, check out the LG 34GP950G-B.

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 'Normal' because it provides the fastest response time while keeping overshoot at a minimal level.

The response time at 120Hz remains fantastic. Motion looks smooth with the 'Normal' overdrive setting, and there isn't any overshoot like with 'Fast' and 'Faster'.

The LG 34GP83A-B's response time at 60Hz is great. 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. It's great because you don't need to change the overdrive setting if the frame rate of your game drops.

The LG 34GP83A-B 34 inch gaming monitor doesn't have Black Frame Insertion feature.

The backlight is entirely flicker-free, which helps minimize image duplication and reduce eye strain.

The LG 34GP83A-B has exceptionally low input lag to provide incredibly responsive gameplay.

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-B works well with the PS5. It downscales a 4k image, which results in a sharper image than a native 1440p signal. However, the PS5 doesn't support ultrawide gaming, so you'll see black bars on the sides.

This monitor works well with the Xbox Series X. It downscales a 4k image, which results in a sharper image than a native 1440p signal. 1440p @ 60Hz only works if you enable the HDMI override setting, which disables VRR. The Xbox doesn't support ultrawide gaming, so you'll see black bars on the sides.

The LG 34GP83A-B works well with recent M1 MacBooks. The 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. Windows return to their original position when you wake the laptop up from sleep or open the lid, which is great.

The LG 34GP83A has a few additional features, including:

• Crosshair: Adds a virtual crosshair on the screen.
• Black Stabilizer: Makes objects more visible in dark scenes.
• Reader Mode: Blue light filter to help reduce eye strain.
