Choosing Between Today's Premium 98-inch TVs: TCL QM8 vs LG UT90

When you're looking to create a truly cinematic experience at home, 98-inch TVs represent the pinnacle of consumer displays. Today, we're comparing two impressive contenders: the TCL 98" QM8 Series ($2,999) and the LG 98" UT90 Series ($2,499). Both released in the last year, these TVs showcase how far large-format display technology has come.

Understanding the Category

The 98-inch TV category has seen dramatic improvements in both technology and affordability. Just two years ago, TVs this size cost upwards of $10,000. Now, thanks to manufacturing advances and increased competition, we're seeing excellent options at much more approachable prices.

These massive displays aren't just bigger versions of standard TVs - they require special consideration for:

• Room size and viewing distance (ideally 12-15 feet)
• Brightness and ambient light control
• Mount strength and installation requirements
• Processing power to handle the massive pixel count

Display Technology: A Key Differentiator

The TCL QM8 uses Mini-LED technology, which places thousands of tiny LED lights behind the screen for precise brightness control. With over 5,000 dimming zones, it can make parts of the screen extremely bright while keeping others completely dark. This creates stunning contrast that's especially noticeable in HDR content.

The LG UT90 uses a more traditional LED backlighting system with fewer dimming zones. While still capable of excellent picture quality, it can't match the precise control of the TCL's Mini-LED system. However, LG's processing technology helps compensate, particularly in handling color transitions and motion.

In my testing, the difference is most noticeable when watching HDR movies with lots of contrast, like space scenes or nighttime cityscapes. The TCL's ability to make stars pop against a perfectly black background is impressive.

Brightness and HDR Performance

Here's where we see the biggest technical gap between these TVs:

The TCL QM8 can reach an astounding 5,000 nits of peak brightness. For context, most TVs max out around 1,000 nits, and even direct sunlight is about 1,600 nits. This extreme brightness capability means:

• HDR content looks more dynamic and realistic
• The TV performs well even in bright rooms
• Highlights in movies and games really pop

The LG UT90 reaches about 2,500-3,000 nits, which is still excellent but noticeably less bright. However, it often handles color accuracy better out of the box, and some viewers might prefer its more natural approach to HDR.

Gaming Features

Both TVs support modern gaming features, but there are important differences:

TCL QM8:

• Two HDMI 2.1 ports supporting 4K/120Hz
• Variable Refresh Rate up to 144Hz
• Lower input lag in Game Mode
• Better HDR gaming performance due to higher brightness

LG UT90:

• Four HDMI 2.1 ports supporting 4K/120Hz
• Variable Refresh Rate support
• Good input lag performance
• Better for multi-console setups

For serious gamers, the TCL's superior brightness and contrast make it the better choice, though the LG's additional HDMI 2.1 ports offer more flexibility.

Smart Platforms and User Experience

The TCL QM8 runs Google TV, which offers:

• Extensive app support
• Good content recommendations
• Voice control via Google Assistant
• Chromecast built-in
• Regular updates and improvements

The LG UT90 uses webOS, featuring:

• Clean, intuitive interface
• Quick response times
• Good app selection
• Magic Remote functionality
• Better integration with other LG products

Both platforms work well, but Google TV tends to be more aggressive with recommendations and ads, while webOS offers a cleaner, more streamlined experience.

Home Theater Considerations

For dedicated home theater use, consider:

Screen Size and Viewing Distance:

• 98 inches requires about 12-15 feet viewing distance
• Room should be at least 15 feet deep and 12 feet wide
• Consider ceiling height (these TVs are over 4 feet tall)

Audio Integration:

• Both TVs support eARC for external audio systems
• TCL has slightly better built-in speakers
• Consider a dedicated sound system for either TV

Ambient Light Control:

• TCL's higher brightness handles ambient light better
• Both benefit from light control for optimal performance
• Consider blackout curtains for daytime viewing

Value Proposition

At $2,999, the TCL QM8 offers:

• Superior HDR performance
• Better gaming features
• Higher peak brightness
• More precise local dimming

At $2,499, the LG UT90 provides:

• More HDMI 2.1 ports
• Better out-of-box color accuracy
• Cleaner smart interface
• Solid overall performance

The $500 difference represents about 20% of the purchase price, making the TCL's superior performance a reasonable premium for enthusiasts.

Final Thoughts

Both the TCL QM8 and LG UT90 represent excellent values in the large-format TV market. The TCL offers superior technical performance and is worth the premium for enthusiasts who will appreciate its advantages. The LG provides excellent overall performance at a lower price point and might be the better choice for many users.

Remember that either TV will provide an impressive viewing experience, and your room setup and viewing preferences should guide your final choice. Consider professional installation for these massive displays, and don't forget to budget for a good sound system to match the impressive visual experience.
