Our Verdict
LG B7/B7A OLED
LG B8 OLED
The LG B8 is somewhat better than the LG B7A. The LG B8 has slightly better motion handling due to the black frame insertion (BFI) feature, which is great if you play video games. Also, the LG B8 performs somewhat better in temporary image retention if you use it as a PC monitor, although this could be due to panel variance. On the other hand, the LG B7A has marginally better input lag in HDR gaming and marginally better viewing angles, although both TVs are very good in that respect.
