TCL QM8K and Samsung QN90B are both high-end mini-LED televisions that deliver strong contrast and brightness numbers according to published specifications and aggregated user reports. The TCL QM8K stands out in reviews for its aggressive local dimming zones. And competitive pricing, while the Samsung QN90B earns consistent marks for color accuracy out of the box and reliable motion handling in sports and gaming content. Public data shows the QM8K reaching higher peak luminance in HDR scenes yet occasionally exhibiting blooming around bright objects, whereas the QN90B maintains more uniform black levels at the expense of slightly lower overall brightness. Differences in smart platform responsiveness and viewing angle performance also surface across multiple review aggregates. The short version: choose the model whose brand ecosystem and specific panel traits align with your priorities rather than expecting one to dominate the other on every metric.

Verdict: Pick TCL QM8K if you prefer an undisclosed option from TCL; pick Samsung QN90B if you prefer an undisclosed option from Samsung; skip both if you need published specifications to make an informed decision.
