TCL QM7L 55" Mini LED 4K TV vs Samsung QN43QN90F Neo QLED 4K TV

The TCL QM7L is the stronger pick for most people: at 55 inches it is a bigger screen with far more dimming zones (up to 2,100+) and much higher peak brightness (up to 3,000 nits), which matters for HDR and bright rooms. The Samsung QN90F is a 43-inch set with a 165Hz panel, four HDMI ports and Samsung's polished Tizen smart platform, so it suits smaller rooms, desk setups and gamers who want more inputs. Build quality is solid on both, but owners of TCL Mini LED sets often note panel-to-panel variation and weaker sound, while Samsung buyers pay more for the brand and get a more refined interface.

• Choose the TCL QM7L if you want the biggest, brightest picture for movies, sports and HDR in a normal living room and can live with two HDMI 2.1 ports and Google TV.
• Choose the Samsung QN90F if you need a smaller 43-inch screen, four HDMI inputs, a 165Hz refresh and Samsung's Tizen apps and gaming hub.
