TCL QM8K QD-Mini LED TV vs Samsung QN90F Neo QLED TV

Both are bright Mini LED 4K sets with anti-glare panels and four HDMI ports. The TCL QM8K leans toward gamers and movie watchers: 144Hz native, Game Accelerator 288, up to 3800 dimming zones, Bang & Olufsen audio and Google TV with all three voice assistants. The Samsung QN90F is the safer all-rounder: 165Hz, a glare-free coating owners single out for bright rooms, strong built-in sound and higher owner ratings. Reviewers knock the TCL's sound at high volume; QN90F owners mainly complain about the remote.

  • Choose the TCL QM8K if you want the most dimming zones and gaming features for the money and will add a soundbar.
  • Choose the Samsung QN90F if you want a glare-resistant panel, strong built-in sound and the higher-rated set for a bright living room.

Rated 4.5 out of 5 from 529 ratings, the QM8K is well liked for its brightness, contrast and gaming features. Reviewers also flag weak sound at high volume and a high price, and some complain about the smart interface and setup rather than picture quality.

What people mention

  • BloomingPraisedReviewers report few halos around bright objects thanks to the dense dimming zones.
  • GamingPraisedPlayers like the 144Hz panel and low lag in game mode.
  • SoundCriticisedReviewers say sound quality is weak, especially at high volume, despite the Bang & Olufsen tuning.

Samsung QN90F Neo QLED TV

Questions and answers

Which is better for gaming?
The Samsung QN90F has the higher refresh rate at 165Hz. The TCL QM8K counters with Game Accelerator 288 and a 144Hz native panel. Both have four HDMI ports and low lag; pick the Samsung for the extra headroom, the TCL for its gaming menu features.
Which handles a bright room better?
Both have anti-glare panels and high brightness. QN90F owners repeatedly praise the glare-free screen in sunny rooms. The TCL's CrystGlow panel is also anti-reflective and reaches very high HDR brightness, so either works; the Samsung has the stronger owner track record here.
Do I need a soundbar with either?
With the TCL QM8K, yes, if you watch loud action or sports; reviewers call its sound weak at high volume. The Samsung QN90F's built-in sound draws positive comments, so a soundbar is optional.
Which lasts longer?
Neither maker publishes a lifespan figure, and both use similar Mini LED backlights. Owner ratings favor the Samsung slightly, but build quality is close. Buy the extended warranty if you keep TVs past five years.
Is the Samsung worth stepping up to over the TCL?
Step up if glare control, built-in sound and the higher owner rating matter more than dimming zones and gaming features. Stay with the TCL if you want the most dimming zones and plan to add your own audio.
Does either support Dolby Vision?
The TCL QM8K supports Dolby Vision. The Samsung QN90F uses HDR10+ and does not support Dolby Vision. If you stream a lot of Dolby Vision content, that favors the TCL.
