Our Verdict

Samsung QN90F

TCL QM8K

The TCL QM8K is much better than the Samsung QN90F. The TCL delivers a more impactful HDR experience thanks to its higher peak brightness and much better local dimming, with deeper, more uniform blacks and smoother zone transitions. The TCL also delivers better colors, with a wider color gamut and better color saturation.

    I bought the QM8K, which I use about 90% of the time as a monitor, and I preferred it over the QN90F, even though the QN90F is listed as one of the best “monitor TVs.”

    Other than reflections—which can matter in some monitor setups—the QM8K comes out on top in most other areas, most notably because it uses RGB instead of BGR. Also, when using a TV as a monitor, local dimming usually gets turned down, so native contrast ratio becomes more important.

    Here you guys have the TCL above the Samsung QN90F but on the following link you have the Samsung above the TCL: https://www.rtings.com/tv/reviews/best/tvs-on-the-market Which one is it

    I think you misread, as the QN90F isn’t even mentioned in that link, it’s the S90F, which is a different TV.
