QM6K (55-inch)

The QM6K is the entry point into real mini-LED, a 55-inch set that brings local dimming, quantum-dot color, and Dolby Vision down to a budget that used to buy only basic edge-lit LCDs.

Read the product overview

It is a 2025 model aimed squarely at value shoppers, so it is brighter and more contrasty than any standard LED TV in its price band, though its modest zone count and 60Hz-to-120Hz panel (depending on configuration) mean it is a step below the brighter QM851G. For a secondary TV, a bedroom, or a first 4K HDR set on a strict budget, it delivers a genuine modern picture without asking for much money. Just temper expectations on peak brightness and gaming features against the pricier mini-LEDs above.

How we assess prices

We use in-stock offers checked within 72 hours. Scores compare the current offer with that retailer’s observations from the last 90 days, requiring at least 14 observed days and a price from about 30 days ago. Suspect records withhold the score. Retailer conditions and prices can change.
