LG QNED90T/LG QNED91T review: Two minute review

The LG QNED91T, the company's flagship 4K model in its mini-LED ‘QNED’ range, is a TV with mixed performance. It’s stacked with smart and gaming features that will keep many people happy, but the picture and sound quality are inconsistent, succeeding in some areas, but failing in other crucial ones. It’s worth noting that in the US, this TV is called the LG QNED90 and comes with a pair of feet instead of a central pedestal stand.

Priced at $1,799 / £1,699 / AU$2,995 for the 65-inch version I tested, this is roughly in the same category as many other mini-LED sets of this size, meaning the QNED91T has plenty of competition. 

Picture quality is the most inconsistent aspect of the QNED91T. It has fantastic picture detail and colors that stand out in brighter scenes, but poor backlight control results in blooming issues that are especially visible in darker scenes. Off-center viewing also results in faded contrast and even more obvious backlight blooming. Unfortunately, this keeps the QNED91T from fulfilling its true potential, falling short of some of the best TVs such as the Samsung QN90C, another mini-LED model. 

Audio quality on the QNED91T is again mixed, with meaty bass and clear dialogue having to coexist with average virtual surround sound performance and an uneven sound balance. The TV’s AI Sound Pro mode can improve the balance but sacrifices bass performance in turn. Some may find the QNED91T’s built-in sound adequate, but most would benefit from adding one of the best soundbars. 

Design-wise, LG took a simple approach with the QNED91T, favoring functionality over looks. Its bulky weight makes it feel reassuringly solid but adds a more old-school appearance. That’s not necessarily bad, but it’s something for those who place design high up in their list of requirements to bear in mind. 

LG’s smart webOS smartTV platform continues to be one of the best. The version on the QNED91T, webOS 24, presents a sleek home menu with plenty of opportunities for customization and organization, and it’s both visually appealing and user-friendly. Not much has changed since last year’s webOS 23. There are new features such as an AI Chatbot and customizable profiles, though the latter feature is currently only available in the US. 

The QNED91T is a great performer when it comes to gaming, and has all the gaming bells and whistles you could need. Gameplay is smooth and responsive in any situation. But the QNED91T is sadly held back from greatness by the same picture issues that plague it with movies and, despite valiant effort, won't find itself amongst the best 120Hz TVs. 

Although it has some great features, the QNED91T's picture quality issues are hard to overlook. It thrives in some settings, but ultimately there’s too much inconsistency for the QNED91T to rank among the best TVs.

LG QNED90T/LG QNED91T review: Benchmark results

LG QNED90T/LG QNED91T review: Features

• Built-in with LG’s a8 AI Processor 4K 
• Mini-LED backlight with LG’s NanoCell layer 
• Dolby Vision support 

Serving as the flagship QNED, which combines a mini-LED backlight with LG’s quantum dot NanoCell technology, the LG QNED91T aims to deliver bold brightness and color while maintaining good contrast – something it does with mixed results. 

The QNED91T features LG’s a8 AI Processor, the same found in other 2024 models including the LG B4 and LG QNED87/85, that aims to emulate the performance of last year’s LG C3, particularly in terms of brightness – which it achieves. 

The a8 AI Processor enables features for AI Picture Pro, including AI Super Upscaling and Dynamic Tone Mapping, and AI Sound Pro, including Virtual Surround and AI Clear Sound. It’s also responsible for AI Picture Wizard, which helps you create your preferred picture settings. This is done by choosing your favorite images from a group of different types such as bright landscape, sunset, nighttime and more, which Ai Picture Wizard uses to create your personalized setting. 

For HDR, the QNED91T supports Dolby Vision, HDR10 and HLG formats, but not HDR10+. 

The QNED91T is well stocked with gaming features, with four HDMI 2.1 ports supporting 4K 120Hz, VRR including AMD Freesync, and ALLM and HGiG support. It also features LG’s Game Optimizer, which activates the optimum settings for gaming and allows customization of gaming settings on the fly such as black level, genre and more. 

Audio is provided by a 2.2 speaker system totaling 40W of power with support for Dolby Atmos and DTS:X. While it's not the most mind-blowing of speaker configurations, it provides sufficient punch and there are several preset sound modes including AI Sound Pro. 

The QNED91T comes with the latest iteration of LG’s smart TV platform, webOS 24. While there haven’t been any major changes, the home page has been redesigned. It still has Quick Cards, which enable you to organize apps into categories such as Music, Sports, Games and more. It also supports all major apps including Netflix, Prime Video, Disney Plus as well as Freeview Play and its apps in the UK such as BBC iPlayer and ITVX.  

New features in webOS 24 include an AI Chatbot assistant and the ability to create up to 10 profiles that store each user’s settings and personalized TV and movie recommendations. LG has also committed to five years’ worth of updates on select TVs, including the QNED91T, meaning the latest iteration of webOS will appear via a firmware update for the next five years. 

• Feautres score: 4.5 / 5

LG QNED90T/LG QNED91T review: Picture quality

• Excellent detail and bold colors 
• Backlight blooming issues  
• Limited viewing angle  

The LG QNED91T faces much competition in the mini-LED TV category from the likes of Samsung, Sony, TCL and Hisense, with the latter two providing more budget-friendly options. Sadly, it falls short of some of its major rivals. 

Mini-LED TVs tend to excel at brightness and the QNED91T on the surface has a bright picture, particularly when displaying HDR images. When I measured it on a 10% HDR white window, the results were 1,274 nits and 1,132 nits in Standard and Filmmaker Mode respectively. It also yielded 671 and 601 nits respectively in those modes when I measured a 100% full-screen HDR white window. Those are good numbers overall, but they fail to match the likes of the Samsung QN90C, Sony X95L and Hisense U8K. 

After some casual viewing with both HD and 4K HDR sources and cycling through the various picture presets, I established that the most accurate picture mode was Filmmaker Mode, although Standard and Cinema are two alternatives that deliver a brighter image. 

First starting with broadcast TV, the QNED91T did an effective job of upscaling, but lower-resolution pictures still had a comparatively fuzzy appearance. HD broadcast TV had cleaner textures overall with good contrast and color, and when viewed in Standard mode, a brighter look as well. 

Moving onto 4K HDR movies with Filmmaker Mode’s default settings active, the QNED91T demonstrated excellent image detail in faces and clothing when watching Top Gun: Maverick. This impressive detail carried over to demo footage on the Spears & Munsil UHD Benchmark Blu-ray. Rocky landscapes and forests had refined edges and a good sense of depth. Studio shots of owls and lizards again showed realistic detail, with feathers and scales having a 3D-like quality. 

The QNED91T also excelled when it came to color. Viewing the throne room lightsaber sequence in Star Wars: The Last Jedi, streamed through Disney Plus, the vibrant reds carried plenty of vivid punch and never looked overblown. Lightsabers took on a bold, glossy sheen that showcased the QNED91T’s HDR highlights. Turning back to Spears & Munsil, green trees and blue skies popped off the screen. 

When measuring the QNED91T’s UHDA-P3 and BT.2020 color gamut coverage using Portrait Displays’ Calman calibration software, the QNED91T yielded 96%  and 72.2% respectively. Those are both good results so it’s no surprise colors in 4K HDR programs looked good. Color accuracy Delta E values averaged out to 1.1 (we typically look for below 3) in Filmmaker Mode, which is an outstanding result. 

When viewing both the opening Darkstar flight sequence in Top Gun: Maverick and the Batmobile chase sequence in The Batman, the QNED91T demonstrated excellent motion handling, even in Filmmaker Mode with all motion settings turned off. Quick panning shots and long left-to-right sequences showed little to no sign of judder or stutter and motion was incredibly smooth. 

The Batman is also where the QNED91T started to show weaknesses in the picture department. Black levels were decent in some cases and contrast was rich enough, but when viewing dark scenes such as the first crime scene investigation, backlight blooming was very apparent. Lights in the darkened hallway had a clouding effect that changed the deep, black shadows to a dark gray. 

Changing the Local Dimming,  set to Low by default, to High in the TV’s Brightness settings reduced some backlight blooming issues. But this also resulted in some black crush, with objects in dark scenes such as the bat symbol on Batman’s chest in The Batman starting to disappear. Even then, some backlight blooming was still present. 

An issue that some mini-LED TVs suffer from is poor viewing angles, although models such as the Samsung QN90C and Sony X95L have features to improve this. Unfortunately, viewing angles were an issue with the LG QNED91T. When viewed off-axis, backlight blooming, particularly in dark scenes, became apparent, with large, blocky squares of the backlight shining through at extreme angles. Contrast and color saturation also faded when the TV was viewed from off-center seats. 

Finally, although I didn’t expect the LG to beat the Samsung S95D’s OLED Glare Free screen or the anti-reflection features of its more premium mini-LED sets, I expected the QNED91T to handle reflections better than it did. Under harsh lighting conditions in our testing lab, mirror-like reflections were an issue, which made darker scenes very difficult to see. And with the overhead lights dimmed, other light sources in the room were still reflected on the TV’s screen. 

• Picture quality score: 3.5 / 5

LG QNED90T/LG QNED91T review: Sound quality

• Decent bass levels 
• Clear dialogue  
• Average virtual surround sound 

With a 40W, 2.2 speaker configuration and Dolby Atmos/DTS support, the QNED91T has perfectly adequate built-in audio, though it lacks the sound prowess of rivals such as the Sony X95L. The QNED91T’s speakers may suit some, but generally one of the best soundbars would be an improvement. 

I found Cinema with its warmer profile to be the best sound preset. The QNED91T displayed strong dialogue clarity across most movies and TV shows I watched, from broadcast TV to intense action movie sequences. During the chaotic Batmobile chase in The Batman, speech came through clearly despite loud background noise and a driving score. 

Bass was another highlight, aided by the Cinema sound preset’s warm profile and the QNED91T’s deeper design. Even with the QNED91T’s relatively average power, the rumble of the Batmobile from The Batman and jets in Top Gun: Maverick had plenty of heft and weight. 

Despite Dolby Atmos support, I found the QNED91t’s effects processing to be average. Some effects were present, such as screeching wheels in the Batmobile chase in the Batman but the pounding rain was missing altogether. And in Top Gun: Maverick, background effects from within the cockpit were lost behind the rumble of the engines. 

With AI Sound Pro active, the overall volume and surround sound effects were heightened, but I found dialogue to be on the harsher side and bass reduced. While some may prefer this brightening of the mix, I preferred the Cinema sound preset. 

• Sound quality score: 3.5 / 5

LG QNED90T/LG QNED91T review: Design

• Solid, central stand (on model tested in UK) 
• Chunkier than other TVs 
• Somewhat old-school, basic look 

The QNED91T has somewhat of an old-school design, with a deeper-than-average body and matte gray appearance on the back that harks back to older LCD models. It isn’t the deepest TV on the market (look at the Panasonic MZ2000 for that) but it's still surprisingly chunky. The bezel is trim, however, giving the picture nearly the full scale of the screen. 

With a central, metal stand (on the 65-inch version I tested in the UK), the QNED91T feels reassuringly solid and sturdy. However, it’s worth noting that this is a weighty TV at around 35 kg with the stand attached. In the US, the QNED90 comes with support feet and while I can’t comment on their appearance, the TV itself weighs in at 69.2 lbs with its feet attached. 

Connections are housed in a rear panel and feature four HDMI 2.1 and three USB ports, optical digital audio, and an RF for broadcast and satellite TV. The QNED91 also has  Bluetooth and Wi-Fi capabilities as expected. 

Like most LG TVs, the QNED91T comes with LG’s Magic Remote. This has a central wheel and arrows for scrolling and navigation, or its pointer can be used instead. It also has a built-in mic for voice control and quick access options for apps including Netflix and Prime Video. 

• Design score: 4 / 5

LG QNED90T/LG QNED91T review: Smart TV & menus

• LG’s webOS 24 smart TV platform
• Quick Cards for app organization
• Home menu trimmed down from previous generation     

The QNED91T features webOS 24, the latest iteration of LG’s smart TV platform. The home menu has been trimmed down and tidied compared to previous versions, with a smaller top banner allowing more space for apps and tailored recommendations. All in all, it’s a welcome redesign. 

Carrying over last year’s Quick Cards, which lets apps be organized by category such as Music and Office, there is the introduction of a more refined Sports card and an an Accessibility feature. The Sports card features the useful My Team function that allows you to receive live updates, scores and recommended videos based on your chosen team from sports such as baseball, basketball, soccer, American football and more. Accessibility includes the AI Chatbot, which can be used to diagnose and solve technical issues such as ‘The screen is too dark’ or ‘The volume is too low’. I found it effective enough, brightening the screen when asked, but it did seem on the basic side. 

LG's webOS 24 continues to be amongst the best smart TV platforms for settings and menus, with the Quick Menu providing an easy way to change important settings such as picture and sound modes without having to navigate away from the screen. There are also plenty of advanced adjustments for those who like to play with picture and sound settings. 

•  Smart TV & menus: 4.5 / 5 

LG QNED90T/LG QNED91T review: Gaming

• Four HDMI 2.1 ports
• LG Game Optimizer 
• Picture still affected by backlight blooming  

The QNED91T has a good stock of gaming features across its four HDMI 2.1 ports, including 4K 120Hz, VRR with AMD FreeSync support, ALLM and HGiG. LG’s Game Optimizer also provides the best settings for gaming and allows adjustment on the go using an easy to access and navigate menu. 

Playing Battlefield V on Xbox Series X felt smooth and responsive on the QNED91T. When in graphically intense battle sequences or when quickly scoping across landscapes to spot enemies, I saw no signs of tearing, stuttering or judder. Setting the game genre to FPS on the Game Optimizer enhanced this further by smoothing out quick camera cuts. 

When I measured the QNED91T’s input lag using the Leo Bodnar 4K HDMI input lag tester, it gave a result of 15ms at 4K 60Hz. Although still an acceptable result, that’s higher than what you typically find on the best gaming TVs. 

For graphics, the QNED91T excelled and suffered in the same areas as it did with movies. Colors in brighter sequences were still vibrant and punchy, and textures were clear on every part of the weapon and surrounding environment. But backlight blooming was still an issue, and that meant night missions in Battlefield V took on a gray rather than a black tone, and lamps within a stealth mission had a halo around them that bled into the night sky overhead.  

• Gaming score: 4 / 5

LG QNED90T/LG QNED91T review: Value

• Competitive mini-LED market 
• Good range of smart features 
• Inconsistent picture affects value  

The QNED91T is priced at $1,799 / £1,699 / AU$2,995 for the 65-inch version I tested, though there are price reductions available (up to 20% off in some cases). At that price, there is plenty of new TV competition in 2024 such as the 65-inch Hisense U8N, which is priced at $1,499 / £1,799 / AU$2,795 (although we’ve seen it as low as $1,099 in the US). And there’s also the Samsung QN90D, though it's priced at a much more premium $2,699 / £2,699 / AU$3,995 for the 65-inch model.

Despite a good list of smart and gaming features, it’s tough to overlook that the QNED91T’s picture is similar to a budget TV due to its backlight blooming and viewing angle issues. It’s also tough to overlook that 2023 TVs such as the Hisense U8K and Sony X95L offer better performance and are available for less.

How I tested the LG QNED90T/LG QNED91T

• Tested using SDR and HDR sources
• Tested in a lab with varying lighting conditions
• Measurements taken using Portrait Displays' Calman Calibration software

After some initial causal viewing, I determined the LG's Filmmaker Mode picture preset was the most accurate. I used this for my subjective testing and for measurements using specialized equipment.

For subjective testing, I viewed both lower-resolution and high-definition broadcast TV, and HDR sources such as 4K Blu-ray. I used reference scenes from several movies to test for black levels, contrast, color, motion and more. I also used these same reference scenes to test the QNED91T's built-in audio performance.

To test gaming performance, I used an Xbox Series X and used Battlefield V, looking for smoothness of gameplay while analyzing graphics quality. I also used a Leo Bodnar 4K HDMI Input Lag Tester to test the QNED91T's input lag. 

For objective testing I used specialized equipment including a test pattern generator, colorimeter and Portrait Displays' Calman calibration software to record the results. I tested SDR and HDR brightness levels, color and grayscale accuracy and color gamut coverage.
