If you're looking for overall picture quality and exceptional gaming performance, consider the LG B1 (OLED), although it may be slightly more expensive. This TV is especially strong in dark rooms but doesn't perform as well in bright environments. Alternatively, the Samsung QN90B (LCD) is a bit more affordable and offers better performance in bright rooms, but its picture quality and gaming performance are not quite as high as the LG B1. It comes with great speakers if sound is a concern. Both TVs have similar connectivity options. If you plan on using your TV as a large monitor, the Samsung has a slight edge in performance for this use. Give Feedback

"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."
