A:Answer Since it is an LG OLED panel, the peak brightness is pretty predictable. Unless it uses Panasonic's "special internal cooler" to pump brightness up to 1000 nits, the Vizio OLED will be between 650 (on the low end, similar to a B9) and 800 nits (on the high end similar to the C9), but likely around 700 to 750 (similar to the CX). All OLED TVs pretty much fall into this range and we don't expect the Vizio to be any different. Remember that over 800 nits, you will increase. your risk of burn-in (thus Panasonic's special cooler).
