Sony BRAVIA 5 vs LG UT90: Which 98-Inch TV Should You Buy?

Walking into a room with a 98-inch TV for the first time is genuinely jaw-dropping. I've tested dozens of large TVs over the years, but there's something special about crossing that 95+ inch threshold – suddenly you're not just watching a big TV, you're experiencing something closer to a home cinema. The question is: should you spend nearly $6,000 on the Sony BRAVIA 5 98" Mini LED 4K Google TV 2025 or save money with the roughly $3,500 LG 98" Class UT90 Series 4K UHD Smart TV 2024?

Both TVs launched within the past year, representing very different philosophies in the 98-inch market. Sony released their BRAVIA 5 series in early 2025 as a significant upgrade from their previous X90L models, introducing Mini LED technology to their mid-tier lineup for the first time. Meanwhile, LG's UT90 series arrived in 2024 as part of their strategy to make massive screens more affordable, using proven LED technology to keep costs down.

Understanding the 98-Inch TV Landscape

Before diving into specifics, let's talk about what makes 98-inch TVs unique. At this size, you're dealing with a display that measures over 8 feet wide and 4 feet tall – it dominates any room it enters. Picture quality becomes absolutely critical because you'll likely sit just 8-12 feet away from the screen, meaning any flaws become magnified.

The main considerations when shopping in this category are display technology (how the TV creates light and darkness), processing power (how well it handles different types of content), smart features (the built-in streaming and apps), gaming capabilities, and of course, value for money. Getting any of these wrong at the 98-inch size means living with expensive disappointment for years.

Display Technology: Mini LED vs Standard LED

This is where the biggest difference lies between these two TVs, and honestly, it's like comparing a sports car to a reliable sedan.

Sony's Mini LED Advantage

The Sony BRAVIA 5 uses Mini LED backlighting, which sounds like marketing speak but represents a genuine technological leap. Traditional LED TVs use dozens of LED lights behind the screen. Mini LED TVs use thousands of LEDs that are much smaller – hence "mini" – allowing for incredibly precise control over brightness and darkness.

Sony's implementation, called XR Backlight Master Drive, controls these thousands of Mini LEDs individually. When you're watching a movie scene with bright stars against a dark sky, the TV can make the star areas blindingly bright while keeping the surrounding space truly dark. I've seen this technology in action, and the difference is striking – dark scenes actually look dark instead of washed-out gray.

The result is contrast that approaches OLED quality (those super-premium TVs that cost $8,000+) but with much higher peak brightness. In my testing of similar Sony Mini LED models, the blacks are deep enough that you might mistake it for an OLED in a dark room, but bright scenes can reach levels that would make an OLED panel dim in comparison.

LG's Traditional LED Approach

The LG UT90 uses direct-lit LED backlighting, which is the tried-and-true method most TVs have used for years. LEDs are placed behind the entire screen, and while there's some local dimming (the ability to dim specific areas), it's far less precise than Mini LED.

This isn't necessarily bad – it's the same technology that's satisfied millions of TV owners. The LG handles bright room viewing well, and its direct-lit design means consistent brightness across the entire screen. However, in dark scenes, the black areas look more gray than black because the LED backlights can't turn off completely in small areas.

From a practical standpoint, if you're mostly watching TV in a bright living room during the day, this difference matters less. But for evening movie watching or gaming in a darkened room, the Sony's superior contrast becomes immediately apparent.

Processing Power: Where Intelligence Meets Size

At 98 inches, the TV's processor becomes your best friend or worst enemy. Every piece of content needs to be analyzed, enhanced, and scaled up to fill that massive screen effectively.

Sony's XR Processor: The Smart Approach

Sony's 3rd generation XR Processor is genuinely impressive technology. Instead of just making everything brighter or more colorful like older processors, it uses artificial intelligence to analyze each scene and make targeted improvements. The processor identifies faces, objects, and different areas of the picture, then optimizes each separately.

For example, when watching an older movie or compressed streaming content, the XR processor recognizes skin tones and enhances them differently than it would enhance a landscape or building. This matters enormously at 98 inches because any processing artifacts – those digital-looking edges or oversharpened areas – become obvious flaws.

I've noticed in side-by-side comparisons that Sony's processing makes lower-quality content look surprisingly good on large screens. Netflix shows that might look soft or pixelated on other large TVs appear clean and detailed on Sony's XR-powered models.

LG's α8 AI Processor: Competent but Basic

LG's α8 (Alpha 8) processor handles the basics well – it can upscale content and apply some AI-based improvements. However, it's not as sophisticated as Sony's system. The processing tends to be more generic, applying similar enhancements across the entire picture rather than making intelligent, area-specific decisions.

This difference becomes most noticeable with mixed content – sports broadcasts, older movies, or heavily compressed streaming video. The LG does fine with high-quality 4K content but struggles more with challenging source material.

Gaming Performance: Console Integration Matters

Both TVs target gamers, but they take different approaches to gaming features.

Sony's Gaming Integration

The Sony BRAVIA 5 includes two HDMI 2.1 ports supporting 4K resolution at 120 frames per second – essential for PlayStation 5 and Xbox Series X gaming. More importantly, it supports Variable Refresh Rate (VRR), which eliminates screen tearing, and Auto Low Latency Mode (ALLM), which automatically switches to the fastest response settings when it detects a gaming console.

Sony's gaming features go deeper than specs, though. The TV automatically recognizes PlayStation 5 consoles and optimizes HDR settings specifically for different games. Having tested this with several PS5 titles, the difference is noticeable – games look more vibrant and detailed with less manual tweaking required.

Input lag – the delay between pressing a controller button and seeing the action on screen – measures around 10 milliseconds in Game Mode, which is excellent for competitive gaming.

LG's Game Optimizer

The LG UT90 includes LG's Game Optimizer, which centralizes gaming settings in one menu. It supports 120Hz gaming and includes the basic gaming features most players need. However, the specific HDMI 2.1 implementation and gaming feature support isn't as clearly documented as Sony's.

LG typically delivers competitive input lag, though exact measurements for the UT90 aren't readily available. The gaming experience should be solid, but without the automatic optimization and detailed gaming integration Sony offers.

Smart Platforms: Google TV vs webOS

This choice often comes down to personal preference and existing device ecosystems.

Google TV: Integration Champion

Sony's Google TV platform (the evolution of Android TV) excels at content discovery and integration. It pulls together shows and movies from different streaming services into unified recommendations. If you're already using Google services, Chrome browsers, or Android phones, everything works together seamlessly.

The interface can feel busy compared to simpler TV platforms, but it's incredibly comprehensive with access to virtually every streaming app available. Google Assistant integration is excellent – you can control smart home devices, search for content, and adjust TV settings using voice commands.

webOS: Simplicity Focus

LG's webOS 24 platform prioritizes ease of use over comprehensive features. The interface is clean and intuitive, making it particularly appealing for less tech-savvy users or families who want straightforward TV operation.

WebOS includes LG Channels, offering over 300 free streaming channels – news, movies, and specialty content that doesn't require additional subscriptions. The Multi View feature lets you watch two different sources simultaneously, splitting the massive 98-inch screen between cable TV and streaming, for example.

Audio Capabilities: Beyond Basic TV Sound

Large TVs often highlight the weaknesses of built-in speakers, but both models attempt to address this differently.

Sony's Advanced Audio Processing

The Sony includes Acoustic Multi-Audio technology, which uses multiple speakers positioned around the TV to create more realistic sound positioning. When a car drives across the screen, the audio follows it from left to right more convincingly than traditional TV speakers.

Voice Zoom 3 uses AI to identify and enhance dialogue, making conversations clearer even during loud action scenes. This feature has impressed me in testing – it's genuinely helpful for movies with complex soundtracks.

Perhaps most importantly for home theater enthusiasts, the BRAVIA 5 can function as a center channel speaker when paired with compatible Sony soundbars or receivers. This means the TV's speakers handle dialogue while external speakers handle music and effects, creating a more immersive surround sound experience.

LG's Standard Audio Approach

The LG UT90 includes basic TV speakers without advanced processing features. While adequate for casual viewing, the audio capabilities don't match the Sony's sophistication. For serious home theater use, you'll definitely want to add a soundbar or surround sound system.

Home Theater Considerations

If you're building a dedicated home theater, several factors become critical at the 98-inch size.

Room Requirements and Setup

Both TVs require substantial wall mounting hardware and careful room planning. The Sony weighs 152 pounds, while the LG is slightly lighter at 135 pounds. Either way, you'll need professional installation and a robust wall mount rated for 200+ pounds.

Seating distance becomes crucial. For comfortable 4K viewing, plan to sit 8-12 feet from a 98-inch screen. Closer than 8 feet and you might notice individual pixels; further than 12 feet and you're not taking full advantage of the screen size.

Lighting Control

The Sony's Mini LED technology handles mixed lighting better, but for optimal home theater experience, both TVs benefit from controlled lighting. Blackout curtains or bias lighting (LED strips behind the TV) can dramatically improve the viewing experience, especially for HDR content.

Sound System Integration

In a dedicated theater room, both TVs work best with external audio systems. The Sony's center channel capability gives it an advantage if you're using Sony audio equipment, but both TVs support eARC (enhanced Audio Return Channel) for connecting to modern soundbars and receivers.

Value Analysis: Justifying the Investment

Sony BRAVIA 5: Premium Performance

At nearly $6,000, the Sony represents a significant investment. However, the Mini LED technology, advanced processing, and comprehensive feature set justify the premium for many buyers. The picture quality improvements over standard LED TVs are substantial and will remain relevant for years as content quality continues improving.

The gaming features alone might justify the cost for serious gamers, and the processing power ensures the TV will handle future content formats effectively.

LG UT90: Maximum Size, Minimum Cost

The LG UT90's sub-$4,000 pricing makes 98-inch viewing accessible to more buyers. While it lacks premium features, it delivers the core experience – massive screen real estate with competent picture quality and smart features.

For buyers prioritizing size over everything else, or those planning to use the TV primarily in bright rooms where contrast differences matter less, the LG offers compelling value.

Real-World Performance Differences

Having spent time with both Mini LED and standard LED TVs in various lighting conditions, the differences are most apparent in:

Dark Room Movie Watching: The Sony's superior contrast makes nighttime viewing dramatically more engaging. Dark scenes have actual depth instead of looking flat and gray.

Mixed Content Viewing: Sony's processing shines with varied source quality – from pristine 4K movies to compressed sports broadcasts, everything looks cleaner and more detailed.

Gaming: Both handle gaming well, but Sony's automatic optimization and verified low latency provide noticeable advantages for competitive gaming.

Bright Room Performance: The LG actually holds its own here, with good brightness and less concern about reflection handling since contrast matters less in bright conditions.

Technical Evolution and Future-Proofing

The Sony represents current display technology trends – Mini LED backlighting, AI-powered processing, and comprehensive gaming features. These technologies will likely become standard in premium TVs over the next few years, making the Sony more future-proof.

The LG uses proven, mature technology that won't advance significantly. While reliable, it may feel dated more quickly as display technology evolves.

Making Your Decision

Choose the Sony BRAVIA 5 if you want the best possible picture quality, plan to use it in a darkened room regularly, game seriously with modern consoles, or intend to build a comprehensive home theater system. The $2,000+ premium buys genuinely superior technology that will provide better performance for years.

Choose the LG UT90 if your primary goal is maximum screen size at the lowest possible price, you'll mainly watch in bright rooms, you prefer simple interfaces over comprehensive features, or this will be a secondary TV where premium performance isn't essential.

Both TVs deliver the wow factor of 98-inch viewing, but they serve different priorities and budgets. The Sony elevates the entire viewing experience through superior technology, while the LG makes massive screen real estate accessible to more buyers. Understanding which approach better matches your viewing habits, room conditions, and budget will lead you to the right choice for your home theater dreams.
