  • β€’Extremely bright display with peak brightness up to 5,000 nits, making it perfect for viewing in bright rooms.
  • β€’Dolby Vision IQ and HDR10+ support enhances HDR content for dynamic and immersive visuals.
  • β€’Google TV interface is smooth, fast, and comes with ample 64GB storage for apps, plus easy access to popular streaming services like Netflix and Disney+.

  • β€’The bezeess, sleek metal design adds a premium aesthetic to the large 75-inch screen.

Cons

  • β€’Sound quality, while decent, is not exceptionalβ€”many users recommend connecting to an external AV receiver or sound system for best audio.
  • β€’Remote control lacks numeric buttons and dedicated HDMI or picture mode shortcuts, which can complicate use and universal remote programming.
  • β€’Some apps, like DirecTV, can experience lag or occasional slowdowns in the Google TV environment.
  • β€’Upscaling loweesolution content (720p or 1080p streams) can be inconsistent, sometimes resulting in grainy or soft images depending on the source.
  • β€’Ethernet port is limited to 100 Mbps speeds; users wanting faster wired internet must invest in a separate USB 3.0 1Gbps Ethernet adapter.
  • β€’A learning curve exists for disabling smart features or motion enhancements fully, requiring use of basic setup or PC mode for optimal viewing preferences.
  • β€’Gaming performance specifically hasn't been thoroughly tested by users yet, so expectations are mostly based on specs rather than handn experience.

Bottom Line

If you're after an impressively bright, vivid 75-inch TV with top-tier contrast, rich colors, and the latest HDR and gaming features, the TCL 75QM851G is a standout option packed with flagship tech at a competitive price point. Its Dolby Atmos sound and deeply immersive picture quality make it well suited for movie buffs and gamers alike. However, if you rely heavily on smart TV apps that need flawless responsiveness or want a remote with all the bells and whistles, this might feel a bit limited. For those seeking better audio out of the box or faster Ethernet without adapters, pairing it with an external receiver or stream box like the Nvidia Shield Pro could elevate the experience even more. If you're curious about other options with potentially stronger sound or smoother app performance, we can help explore those as well.
