TCL vs LG: Battle of the 98-Inch Giants

When you're shopping for a 98-inch TV, you're not just buying a display—you're creating a home theater centerpiece that will dominate your living space for years to come. At this massive size, every technical detail matters more because flaws become magnified across that enormous screen. Today we're comparing two very different approaches to the 98-inch market: the premium TCL 98" QM7K from 2025 and the budget-focused LG 98" UT90 from 2024.

Understanding What Makes 98-Inch TVs Special

The 98-inch TV category sits at the intersection of luxury and practicality. These displays offer cinema-like immersion that smaller TVs simply can't match, but they also expose every weakness in display technology. Poor contrast becomes glaringly obvious. Motion blur is more distracting. Color inaccuracies stand out like sore thumbs.

At the time of writing, 98-inch TVs fall into two distinct price tiers. Budget models typically cost around $1,500-2,000 and use traditional LED backlighting with basic features. Premium models range from $2,500-4,000+ and incorporate advanced technologies like Mini-LED backlighting, quantum dots, and high refresh rate gaming features.

The key considerations for any 98-inch purchase include display technology (which determines contrast and brightness), gaming capabilities (refresh rates and input lag), smart platform longevity, and most importantly, how well the TV performs in your specific room conditions. A TV that looks amazing in a bright showroom might disappoint in your dark basement theater, and vice versa.

The Contenders: Two Different Philosophies

The TCL QM7K represents TCL's 2025 flagship approach: pack premium Mini-LED technology into a competitively priced package. TCL has been aggressively pushing into the premium TV space over the past few years, and the QM7K showcases their latest QD-Mini LED innovations with features that typically cost thousands more from other brands.

The LG UT90 takes a different approach, prioritizing screen size over cutting-edge features. Released in 2024, it's LG's answer to buyers who want the biggest possible display without premium pricing. This strategy makes sense—sometimes having a massive screen with decent performance beats having a smaller screen with perfect performance.

Picture Quality: Where Technology Meets Reality

The most significant difference between these TVs lies in their fundamental display technologies, and this gap has only widened as Mini-LED technology has matured.

Contrast and Black Level Performance

The TCL QM7K uses QD-Mini LED technology with up to 2,500 individual dimming zones. Think of these zones as tiny spotlights that can turn on and off independently. When you're watching a movie with a night scene, the TV can make specific areas completely black while keeping bright elements (like a street lamp) brilliantly illuminated. This creates what's called local dimming, and having 2,500 zones means incredibly precise control.

The LG UT90 uses traditional LED backlighting with approximately 100 basic dimming zones. While this is still technically local dimming, it's like comparing a precision surgeon's scalpel to a butter knife. With fewer zones covering much larger areas, you'll often see "blooming"—where bright objects cause unwanted light spill into dark areas around them.

In practical terms, this difference is dramatic. The TCL QM7K achieves a native contrast ratio of 8,000:1, meaning white areas are 8,000 times brighter than black areas. The LG UT90 typically manages around 1,200:1. When watching dark movies like horror films or space epics, the TCL delivers true blacks that make the LG UT90 look gray by comparison.

Peak Brightness and HDR Performance

Peak brightness determines how well a TV displays HDR (High Dynamic Range) content, which includes most modern movies and shows. HDR content contains information about how bright specific elements should appear—like the sun reflecting off water or a car's headlights at night.

The TCL QM7K reaches 3,000 nits peak brightness, which is genuinely impressive for any TV, let alone one at this price point. For context, a typical sunny day measures about 10,000 nits, while indoor lighting ranges from 100-500 nits. The ability to hit 3,000 nits means HDR highlights have real punch and sparkle.

The LG UT90 peaks at around 800 nits, which is adequate for most content but limits HDR impact. You'll still see HDR benefits like improved color and contrast, but those eye-catching specular highlights—think lightsaber blades or explosions—won't have the same dramatic effect.

This brightness difference also affects daytime viewing. The TCL QM7K can easily overcome room glare and maintain image quality in bright living rooms, while the LG UT90 may struggle in very bright conditions.

Color Reproduction and Quantum Dots

Color reproduction is where the TCL QM7K's quantum dot technology really shines. Quantum dots are microscopic particles that, when hit by light, emit very pure colors. This allows the TV to display nearly 100% of the DCI-P3 color space used by movie studios, producing over one billion distinct colors.

The LG UT90 uses standard LED color filters, achieving about 85% DCI-P3 coverage. While this still produces good-looking images, you'll miss some of the subtle color gradations and vibrant hues that make modern content pop. The difference is most noticeable in nature documentaries, animated films, and content specifically mastered for wide color gamuts.

Both TVs handle standard HD and 4K upscaling well, but the TCL QM7K's AI-powered processing tends to produce cleaner results with less artifacting when watching lower-quality content like streaming video or cable TV.

Gaming Performance: Console Wars Meet Display Tech

Gaming has become a crucial consideration for large TVs, especially as consoles like the PlayStation 5 and Xbox Series X push higher frame rates and resolutions.

Refresh Rates and Response Times

The TCL QM7K supports a native 144Hz refresh rate with its Game Accelerator 288 system, which can handle variable refresh rates up to 288Hz for 1080p content. This means games appear smoother with less motion blur, and fast-paced action stays crisp. The TV also supports AMD FreeSync Premium Pro, which synchronizes the display refresh rate with your console or PC's output to eliminate screen tearing.

The LG UT90 offers 120Hz refresh rate with basic VRR (Variable Refresh Rate) support. While 120Hz is perfectly adequate for current console gaming, the TCL QM7K provides more headroom for future gaming developments and PC gaming at higher frame rates.

Input lag—the delay between pressing a button and seeing the result on screen—is crucial for competitive gaming. Both TVs offer dedicated game modes that reduce processing delays, but the TCL QM7K achieves lower input lag thanks to its more advanced processing pipeline.

HDMI and Connectivity

The TCL QM7K includes two HDMI 2.1 ports capable of 4K at 144Hz, plus two HDMI 2.0 ports. This means you can connect multiple high-end gaming devices without compromising performance. The LG UT90 offers four HDMI ports but with more limited bandwidth for high refresh rate gaming.

For serious gamers building a setup around a 98-inch display, the TCL QM7K provides more flexibility and future-proofing. However, casual gamers using standard consoles will find the LG UT90 perfectly adequate.

Audio: Size Meets Sound

At 98 inches, you'd expect impressive audio to match the massive visual experience, and there's a notable difference between these models.

The TCL QM7K features audio tuning by Bang & Olufsen, the renowned Danish audio company. It includes a 2.1.1 channel system with a dedicated subwoofer for the 98-inch model, plus Dolby Atmos support for spatial audio effects. This creates a more immersive soundscape where audio moves around the room to match on-screen action.

The LG UT90 uses a basic 20W stereo system that's functional but unremarkable. While the sound is clear for dialogue and casual viewing, it lacks the depth and impact that matches a 98-inch visual experience.

That said, most serious home theater enthusiasts pair large TVs with dedicated sound systems anyway. If you're planning to add a soundbar or surround sound system, the audio differences become less significant, though the TCL QM7K's superior audio processing and Dolby Atmos passthrough still provide benefits.

Smart Platforms: The Software That Runs It All

Smart TV platforms determine your daily interaction with the TV, and both brands take different approaches.

The TCL QM7K runs Google TV, which provides access to a vast ecosystem of apps and services. Google TV receives frequent updates and typically supports new streaming services quickly. The hands-free voice control with far-field microphones is genuinely useful—you can change channels or search for content without finding the remote.

The LG UT90 uses webOS 24, LG's proprietary platform. WebOS offers a clean, intuitive interface that many users find easier to navigate than Google TV. However, it sometimes lags behind in app support and updates compared to Google's platform.

Both platforms handle the essential streaming apps (Netflix, Amazon Prime, Disney+, YouTube) without issues. The choice often comes down to personal preference and integration with other smart home devices.

Home Theater Considerations

In a dedicated home theater environment, the performance differences between these TVs become magnified. The TCL QM7K's superior contrast ratio and peak brightness create a more cinematic experience that justifies the premium pricing.

For dark room viewing—which is ideal for most movie watching—the TCL QM7K delivers blacks that rival OLED technology while providing higher peak brightness. This combination is particularly effective for HDR movie content where you need both deep shadows and brilliant highlights.

The LG UT90 works better in brighter rooms where its contrast limitations are less noticeable. If your TV will primarily live in a bright living room with lots of windows, the performance gap narrows considerably.

Screen size becomes more critical in larger rooms. A 98-inch display works best when viewed from 8-12 feet away. Closer than 8 feet and you might see individual pixels; farther than 12 feet and you lose some of the immersive benefits of the large size.

Value Proposition: Premium vs Budget Approach

At the time of writing, these TVs represent fundamentally different value propositions. The TCL QM7K costs approximately $1,000 more than the LG UT90, but delivers technology typically found in TVs costing $4,000 or more.

The TCL QM7K makes sense if picture quality is your primary concern and you have the budget for premium features. The Mini-LED technology, higher brightness, and superior gaming capabilities provide tangible benefits that justify the price premium for many buyers.

The LG UT90 excels at maximizing screen size within a budget. If your main goal is having the biggest possible display for watching sports, cable TV, or streaming in a bright room, the cost savings could be better spent on audio equipment or other home theater components.

Who Should Buy What?

Choose the TCL QM7K if:

• You have a dedicated dark room or theater space
• Picture quality and contrast are top priorities
• You're a serious gamer who wants high refresh rates
• You regularly watch HDR movies and shows
• You can justify the premium pricing for superior technology

Choose the LG UT90 if:

• Maximum screen size within budget is most important
• Your TV will primarily live in a bright, well-lit room
• You're a casual viewer who doesn't need cutting-edge features
• You prefer to spend savings on audio equipment or other components
• You're already invested in LG's ecosystem and prefer webOS

The TCL QM7K represents where TV technology is heading: Mini-LED backlighting with precise control, high brightness for HDR impact, and gaming features that take advantage of next-generation consoles. It's a future-focused purchase that should remain relevant for many years.

The LG UT90 prioritizes practicality and value, delivering a massive screen with solid performance at a more accessible price point. Sometimes that's exactly what you need.

Both TVs will transform your viewing experience simply by virtue of their massive size, but the TCL QM7K does so with significantly more technological sophistication. Whether that sophistication is worth the extra cost depends on your priorities, room setup, and budget. Choose wisely—at 98 inches, this decision will literally loom large in your home for years to come.
