Our Verdict
LG B8 OLED
LG SM8600
The LG B8 and the LG SM8600 use different panel technologies, each with their strengths and weaknesses. The B8 uses an OLED panel, which delivers outstanding dark room performance and crystal-clear motion, thanks to the nearly-instantaneous response time. Unfortunately, the B8 also has a chance of permanent burn-in, which is not an issue on the LG SM8600.
