Our Verdict
LG SJ8500
LG SJ9500
The LG SJ9500 is somewhat better than the LG SJ8500. The LG SJ9500 has better SDR peak brightness, which is important when you watch TV shows in a bright room. Also, the LG SJ9500 has a slightly better gradient and better black uniformity for HDR, which is great when you watch HDR content. The LG SJ8500, however, has lower input lag when you play HDR games, and better 4k input picture as its pixel dimming algorithm doesn't display the artifacts shown on the single color areas of the LG SJ9500.
