Our Verdict
LG SM9500
TCL 8 Series 2019/Q825 QLED
The TCL 8 Series 2019/Q825 QLED and the LG SM9500 have different panel types, each with its advantages and disadvantages. The TCL is more suitable for a dark room where it displays deeper and more uniform blacks thanks to its VA panel. On the other hand, the LG is a better choice if you often watch sports with a group of friends as the image remains accurate when viewed from the side. The LG has also a lower input lag, great for competitive gamers.
