Although they have very similar scores, PerfectRec considers Samsung QN90B (LCD) to be good for sports, while the LG QNED90 (LCD) is only fair.
The Samsung QN90B is better for sports because it handles reflections more effectively and boasts a faster response time, enhancing motion clarity, whereas the LG QNED90, despite having wider viewing angles, falls short in both these critical areas for watching fast-paced sports. Additionally, the QN90B's superior gray uniformity minimizes distractions on the screen during gameplay, a somewhat important factor where the LG QNED90 has lower performance.

"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."
