Which is better for gaming?

Both run a 144Hz native panel with Game Accelerator 288 and four HDMI ports. The QM9K adds Motion Rate 480 and Auto Game Mode, so it edges ahead on motion clarity.

Is the QM9K worth the extra over the QM8K?

At the current prices it is not extra: the QM9K has sold for $999.99 since October 31, 2026, below the QM8K's $1,299.99. It also has more dimming zones and higher rated brightness.

The QM9K is rated up to HDR6500 versus up to 5,000 nits on the QM8K. Both are bright enough for a sunlit room.

Which handles blooming better?

The QM9K's LD6000 dimming with up to 6,000 zones and Halo Control System targets halo-free images, and buyers praise its blooming control. The QM8K uses all-domain halo control but does not publish a zone count.

Do both support Dolby Vision?

The QM9K lists Dolby Vision, HDR10, HDR10+ and HLG. The QM8K's listing only says HDR, so confirm Dolby Vision before buying it.

Neither maker publishes a lifespan figure, so there is no basis to pick one on durability. Compare the warranty terms at checkout instead.

TCL 65-inch QM8K Mini LED QLED 4K TV vs TCL QM9K Series 4K UHD QD-Mini LED QLED Smart Google TV

Both are 65-inch QD-Mini LED TCL sets with 144Hz panels, four HDMI ports, Wi-Fi 6 and Bang & Olufsen audio. The QM9K is the step-up model: more dimming zones (up to LD6000), higher rated brightness (up to HDR6500), IMAX Enhanced, and it has traded as low as $999.99 since October 31, 2026. The QM8K is $1,299.99 at Queen City Homestore as of November 5, 2026, so the QM9K is the better buy unless the QM8K's price drops below it.
