LG QNED75B  TV Review

The LG QNED75B has bad peak brightness in HDR. It's bright enough to deliver a somewhat decent experience in most moderately lit scenes, but small highlight details like the sun reflecting off a car don't stand out at all. Bright outdoor shots are very dim and look flat.

Switching to Game Optimizer makes no difference to the TV's peak brightness in HDR.

The TV has poor peak brightness in SDR. It's bright enough to see bright scenes in a moderately-lit room, but it can't overcome glare from lights or windows facing the screen.

The LG QNED75B has terrible contrast. Blacks are raised and look washed out in all scenes. Although the TV is marketed by LG as a Mini LED model, this is deceiving and only refers to the physical size of the LEDs, as there's no local dimming feature.

There's no local dimming feature, so there are no lighting zones. This means there's no haloing around bright elements against a dark background or subtitles, but the entire image looks gray and washed out.

This TV doesn't have a local dimming feature, so it can't adjust the backlight of individual zones to brighten up highlights without impacting the rest of the image. This means that there are no distracting flickers or brightness changes as bright highlights move between dimming zones.

Switching to Game Optimizer doesn't result in any noticeable difference in dark scene performance. Blacks are still terrible and look gray in any content.

The TV has mediocre black uniformity. Black levels are very uneven across the screen, with some warmer spots near the center and darker areas near the edges. Unfortunately, there's no local dimming feature to improve it.

The LG QNED75B has okay color volume in SDR. It has decent coverage of the DCI-P3 color space, but can't display the full range of reds or greens. It can't display much beyond the DCI-P3 color space, resulting in much worse coverage of the BT.2020 color space. Color volume also varies considerably depending on the lightness of the scene, and it struggles to maintain color saturation in very light scenes.

The TV has disappointing color volume in HDR. It can't display dark, saturated colors at all due to its very low contrast and high black levels. Colors in bright scenes look washed out, and it can't display the full range of colors in either HDR color space.

The LG QNED75B has okay color accuracy before calibration. Its gamma tracking is all over the place, so some scenes look okay while others are crushed. There's also a bit too much red and not enough blue in brighter shades of gray, giving it a very warm color temperature in most scenes. Its color mapping isn't too bad, but there are a few noticeable issues with blues and reds.

The TV is very easy to calibrate and looks nearly perfect after a full calibration. Any remaining inaccuracies aren't noticeable.

The TV has good accuracy in HDR before calibration. The white balance is the biggest issue, with noticeable issues in bright and dark shades of gray. It has great color mapping, with only minor luminance errors. The average color temperature is excellent, but there's not enough blue in dark shades and too much blue in bright ones.

Calibrating the TV in HDR improves accuracy a bit. Color accuracy is even better, with very few noticeable issues. The white balance looks a lot better overall but there are still issues in very bright and very dark shades.

The TV has good PQ EOTF tracking. Black details are noticeably raised by the TV's low contrast, but midtones track extremely well. Content mastered at 600 and 1,000 nits rolls off gently near the TV's peak brightness. Content mastered at 4,000 nits rolls off even more gradually near its peak brightness, which helps preserve fine details in bright parts of the scene but limits how bright they get.

The TV has good low-quality content smoothing. It does a great job reducing macro blocking and other compression artifacts from streaming services, but there's a noticeable loss of fine details that gives the image a slightly waxy look.

The TV has great upscaling. Low resolution content like DVDs are upscaled well, with no obvious over sharpening.

The gradient handling is just decent. There's noticeable banding in dark shades of gray and blue, and all shades of green.

This TV adds very little input lag when set to Game Optimizer, which ensures a responsive gaming experience.

The TV supports all common resolutions up to 4k @ 60Hz. It displays chroma 4:4:4 properly with any signal, which is important for reading clear text from a PC.

The LG QNED75B supports VRR to help reduce screen tearing. Unfortunately, it's not very useful, as the refresh rate range isn't wide enough to work with sources that support Low Framerate Compensation (LFC), so you'll see tearing if your framerate drops below 48Hz.

Unfortunately, the TV has a very high CAD at the max 4k refresh rate of 60Hz, and motion looks very blurry when gaming. There's some overshoot in certain transitions, but it's not enough to cause noticeable inverse ghosting.

This TV doesn't support a 120Hz refresh rate.

Unfortunately, the TV has a very high CAD at the max 4k refresh rate of 60Hz, and motion looks very blurry when gaming. There's some overshoot in certain transitions, but it's not enough to cause noticeable inverse ghosting.

This TV is a 60Hz TV, so it only supports 4k @ 60Hz on the P55. It has Auto Low Latency Mode (ALLM), so it'll automatically switch to Game Optimizer mode when it detects a game being played, which gives you the lowest possible input lag for games.

This TV only supports 4k @ 60Hz Xbox Series consoles. It has Auto Low Latency Mode (ALLM), so it'll automatically switch to Game Optimizer mode when it detects a game being played, which gives you the lowest possible input lag for games. Unlike higher-end LG TVs, it doesn't support Dolby Vision.

The TV's relatively slow response time results in mediocre stutter results. There's some minor stutter in wide, slow-panning shots, but it's better than most LED TVs on the market and not very noticeable.

Adding low levels of motion interpolation actually adds judder, with the TV constantly alternating between a short frame and a long one. While the average frame hold time is lower compared to before, it's incredibly inconsistent and motion looks worse overall.

Unfortunately, the TV doesn't remove 24/25p judder from 60Hz sources like most cable TV boxes or a streaming device with the Match Frame Rate feature disabled. Watching movies from a Blu-ray player or with the native apps is fine, though.

There's no micro judder.

The TV has a poor response time when watching content. All motion is incredibly blurry.

Edge transitions look great, but there are some minor color artifacts around fast-moving objects.

The TV uses pulse width modulation (PWM) to dim its backlight, which introduces flicker that can bother people who are sensitive to it. Unfortunately, it flickers at a slow 240Hz in all picture modes and at all brightness levels, so it can cause headaches and eye strain if you're sensitive to flicker.

The TV doesn't have an optional backlight strobing feature, commonly known as black frame insertion (BFI), to help reduce persistence blur.

The glossy coating on the LG QNED75B does almost nothing to reduce the intensity of direct reflections. Lights and windows facing the TV are reflected back like a mirror and are very clear.

Ambient light has no impact on perceived black levels.

The total amount of reflected light is decent. Unfortunately, bright mirror-like reflections are clear and easy to see, but at least there are no diffraction artifacts like rainbow smearing.

Ambient light has no significant impact on the TV's perceived color volume.

One of the few positives of this TV is its good viewing angle. The image remains accurate even at a moderate angle, so it's an acceptable choice for a wide seating arrangement.

Unfortunately, the LG QNED75B has sub-par gray uniformity. The center of the screen is a bit patchy, which can be distracting when watching sports. The sides of the screen are also considerably darker than the center, which is noticeable in all content.

The TV uses an ADS panel with an RGB sub-pixel layout, so it renders text well as a PC monitor. It uses a KSF phosphor to produce reds, which is a bit better than simple color filters on lower-end models like the LG UA77.

The TV has a limited selection of inputs.

This TV supports eARC, which allows it to pass uncompressed high-quality audio from a connected source to your home theater system or soundbar. Unfortunately, it doesn't support any DTS formats commonly used on physical media.

Unlike most LG TVs, the LG QNED75B doesn't support Dolby Vision.

The TV has a fairly basic design. While the bezels are thin and it doesn't look too bad, it's not very premium, either.

The blade style feet sit at either end of the TV and there's no narrow position for a shorter table.

Footprint of the 75-inch stand: 51.1" x 14.3" x 3.5".

The back of the TV has a very cheap look to it. The inputs are all housed in a central electronics box, so they're difficult to reach without turning the TV. There are clips on either side of the TV to help with cable management.

The LG QNED75B has decent build quality. It's almost entirely made of plastic, so some of the body panels flex easily and feel a bit cheap. There are no obvious construction issues with it, though.

The TV ships with a simple remote with a full set of keys, which some people may actually prefer. The TV is compatible with LG's Magic Remote, though, so you can buy it separately if you want it.

The TV ships with version 26 of LG's proprietary webOS smart interface. It's easy to use, with support for multiple user profiles, a kids mode, and a huge selection of apps. This TV is also part of LG's Re:New program, so it'll eventually receive software updates to newer versions of webOS for the next few years.

Unfortunately, like almost all TVs on the market, the smart interface contains ads, and you can't disable them.

This TV was originally tested on firmware version 43.21.41.

Unfortunately, the TV has a sub-par frequency response. While most TVs lack deep bass, this one is even worse than usual, with very little bass response at all. It has a fairly well-balanced sound profile at low listening levels, but it can't get very loud. The TV has a digital room correction feature, but it requires the LG Magic Remote, which is sold separately.
