Our verdict

The 55QM6K is a compelling feature-focused choice for buyers wanting Mini LED local dimming, broad HDR compatibility, and high-refresh gaming. Buyers prioritizing intense HDR highlights or placement opposite bright windows should compare higher-tier options; the quoted independent review tested the 75-inch QM6K rather than this exact size.

Pros

  • +Mini LED local dimming and quantum-dot color provide a more capable display feature set than basic non-dimming LCD designs.
  • +Native 144 Hz refresh, VRR, and automatic low-latency mode make it a well-equipped gaming option.
  • +Broad HDR-format support, Google TV, and eARC cover common streaming and home-theater needs.

Cons

  • −HDR impact is a compromise: RTINGS' QM6K-series testing found limited HDR brightness rather than premium-level highlights.
  • −The 55-inch model lacks the matte screen coating offered on the 85- and 98-inch QM6K models, making direct reflections an important placement consideration.

Frequently asked

Yes. The supported HDR formats include Dolby Vision IQ, HDR10+, HDR10, and HLG.

Can I connect an eARC soundbar?

Yes. One of its four HDMI inputs supports eARC.

How much space does the 55-inch model need, and can it be wall-mounted?

With its stand, it measures 48.40 inches wide, 29.90 inches high, and 11.89 inches deep. The specified VESA mounting pattern is 300 x 300 mm; follow the TV and mount instructions for installation.
