Our Verdict
LG UM7300
LG SM8600
The LG SM8600 is a little better than the LG UM7300. The SM8600 has a faster response time, which is great for sports, and a wide color gamut, which is great for HDR. The UM7300 can get brighter, which is great for watching TV in a brighter room, and its Automatic Brightness Limiter doesn't change the brightness according to the scene.
