Our Verdict
Vizio M Series 2018
LG SM8600
These two TVs have different panel types, each with their advantages and disadvantages. The Vizio M Series 2018 has a VA panel and is a better choice for those who watch TV in a dark room and sit straight in front. The LG SM8600 has an IPS panel and is more suitable for those who watch TV with some lights on and often sit at an angle. The Vizio can display deeper and more uniform blacks in a dark room and has better HDR performance. The LG, apart from the better refection handling and the wider viewing angles, has a motion interpolation feature for the soap opera effect fans. The LG also supports 1440p and has a lower input lag, which is great for playing video games.
