TCL QM8K First Look: Unboxing, Setup and Gaming
The 2025 TCL QM8K is a premium QD-Mini LED Google TV built around a native 144Hz CrystGlow WHVA panel, full-array local dimming and broad HDR support. During this first look, Tech Steve found the image bright, vivid and colorful, with useful anti-glare performance and good off-axis viewing. Gaming highlights include 4K/120Hz console support, 4K/144Hz PC support on two HDMI inputs, VRR, ALLM, Dolby Vision Gaming and a configurable game bar. The main tradeoffs are that only two HDMI ports support signals above 4K/60Hz and the advertised ultra-high-frame-rate modes require reduced resolution.
Video summary
Tech Steve unboxes and assembles the 2025 TCL QM8K, demonstrates the height-adjustable centered pedestal, examines its approximately two-inch-deep chassis and reviews its connections. He highlights the nearly borderless design, anti-reflective CrystGlow WHVA panel, Google TV platform and B&O-branded audio system. His initial viewing impressions describe a bright, vivid and colorful image with good viewing angles and useful glare reduction. He also demonstrates the game bar and connects both a PlayStation 5 and Xbox Series X. The PS5 reports support for VRR up to 120Hz, HDR and multiple 1440p and 1080p rates, while the Xbox confirms 4K/120Hz, Dolby Vision Gaming, ALLM and VRR support.
Tech Steve Takeaway
The TCL QM8K is a strong option for shoppers who want a bright Mini LED picture, broad HDR compatibility and high-refresh gaming without moving to OLED. Its centered stand makes the 65-, 75- and 85-inch versions easier to place, but gamers with several high-bandwidth devices should plan around having only two 4K/144Hz HDMI inputs.
Picture quality
Tech Steve's initial impression was that the QM8K produces a bright, vivid and colorful image. He also observed good viewing angles from the CrystGlow WHVA panel and effective glare reduction in a room with lights and windows. The QD-Mini LED backlight combines quantum-dot color with full-array local dimming, while TCL's Halo Control System is designed to improve backlight precision and reduce visible blooming. These observations are preliminary rather than a complete picture-quality evaluation.
HDR performance
The QM8K supports Dolby Vision IQ, Dolby Vision Gaming, HDR10+, HDR10 and HLG. TCL advertises up to 5,000 nits of peak HDR brightness across the series, but that figure is a manufacturer peak claim rather than a sustained or Tech Steve measurement. Support for both Dolby Vision and HDR10+ provides flexibility across streaming services, discs and games.
Gaming performance
The native 144Hz panel accepts up to 3840 x 2160 at 144Hz with VRR through HDMI 1 and HDMI 2. PlayStation 5 testing showed 4K/120Hz, HDR and VRR support, while Xbox Series X testing confirmed 4K/120Hz, Dolby Vision Gaming, ALLM and VRR. The game bar provides signal status, aiming assistance, magnification, shadow enhancement, picture presets and an optional movable refresh-rate display. Game Accelerator supports up to 1080p/288Hz on the 65-, 75- and 85-inch models; the 98-inch model is limited to 1080p/240Hz. These reduced-resolution modes are not 4K and do not change the panel's native 144Hz refresh rate.
Motion handling
The QM8K uses a native 144Hz panel and supports VRR up to 144Hz at 4K through its two high-refresh HDMI inputs. TCL's Motion Rate 480 is motion-processing branding based on frame insertion, not a 480Hz physical panel. Detailed film-cadence and motion-interpolation testing was outside the scope of this first look.
Sound quality
The integrated B&O-branded audio system includes up-firing Dolby Atmos drivers and supports Dolby Atmos, DTS:X and DTS Virtual:X. Available sound modes include Movie, Speech, Music, Games, Night, Sports and Custom. Tech Steve showed the speaker-related chassis design but reserved listening impressions for a complete review.
Smart TV experience
Google TV provides the main smart interface, personalized content organization and app access. The QM8K also supports Chromecast, Apple AirPlay 2, Apple HomeKit, Google Assistant and Amazon Alexa. Tech Steve completed the Google TV setup and demonstrated the supplied silver voice remote, which includes conventional navigation, channel and volume controls plus app shortcuts.
What we like
- Bright, vivid initial picture with strong color presentation
- Native 144Hz panel with verified 4K/144Hz VRR support
- Dolby Vision IQ, Dolby Vision Gaming and HDR10+ compatibility
- Anti-reflective CrystGlow WHVA panel with good observed viewing angles
- Useful game bar with VRR, ALLM, aiming and shadow controls
- Narrow height-adjustable centered pedestal on 65-, 75- and 85-inch sizes
- B&O-branded audio with up-firing Dolby Atmos drivers
- Google TV with Chromecast, AirPlay 2 and voice-assistant support
What to consider
- Only HDMI 1 and HDMI 2 support 4K signals above 60Hz
- Advertised 288Hz gaming requires 1080p resolution and is not available at 4K
- The 98-inch model tops out at 1080p/240Hz in its reduced-resolution mode
- The 98-inch model's dual feet require approximately 73 inches of furniture width
- The 85- and 98-inch models use an uncommon 600 x 500 mm VESA pattern
- Published 5,000-nit brightness is a manufacturer peak claim rather than a Tech Steve measurement
Tech Steve verdict
The TCL QM8K combines a bright-looking QD-Mini LED image, effective anti-reflective treatment, broad HDR format support and a native 144Hz panel. It is particularly attractive for console and PC gamers because it supports 4K/144Hz VRR, Dolby Vision Gaming and a useful game bar, although only HDMI 1 and HDMI 2 handle signals above 4K/60Hz. Movie and streaming shoppers benefit from Dolby Vision IQ, HDR10+, Google TV and full-array local dimming, while wide seating arrangements should benefit from the WHVA panel's viewing characteristics. The 65-, 75- and 85-inch models are the easiest to place because of their narrow centered pedestals. The 98-inch model delivers the largest image and the series' documented 3,800-zone claim, but it requires very wide furniture unless wall-mounted and has a lower 1080p high-frame-rate ceiling than the smaller sizes.
