The QM7K spans conventional living-room sizes and a 115-inch installation that needs considerably more planning. What unites them is a quantum-dot LCD with a Mini LED backlight and Google TV. Panel size changes the backlight and some gaming limits along the way.

Pros
- Both Dolby Vision and HDR10+ work with compatible programming.
- A separate audio-return connection leaves fast HDMI inputs available on the tested 65-inch. 1
Cons
- Bright subtitles can expose the limits of zone dimming. 1
- The 65-inch test does not establish 115-inch performance.

- Dolby Vision IQ
- HDR10+
RTINGS saw deep blacks and enough daytime brightness for sports on the 65-inch, with some glow around bright details in dark scenes. The test team counted 966 dimming zones on its sample. A family-level maximum applies to a particular configuration, so it shouldn't be used as the count for every QM7K. 1
Gaming
- High-refresh 4K
- Game Accelerator at reduced resolution
On the 65-inch, two inputs accept 4K at 144 Hz and can run 1080p at 288 Hz. Dropping to 1080p trades fine detail for extra updates, useful for a fast PC game played from several feet away. The 55-inch has a different Game Accelerator ceiling. Check the size you plan to connect. 1
Size and Installation
- 55 to 115 inches
- Google TV
Smaller models can use a central stand, while the 98-inch uses two feet. At 115 inches the physical issue goes well beyond screen diagonal. Use that model's installation guide to establish mounting points, handling requirements and the route into the house before ordering. 1
Alternatives
For evening movies and a smaller room, an OLED avoids the haloing a zone-lit screen can show. The QM7K makes the stronger practical case when a large picture and daytime sport share the budget. Compare it with the preceding QM7 at the same size, since a larger TV's zone count doesn't prove that a smaller one is an upgrade.
Verdict
I'd shortlist the QM7K for a family room, especially if different streaming services and game systems share the screen. Treat the 115-inch as a distinct installation project within that family.
