A:Answer As far as I know, it is a glass screen similar to the C1. However, in reviews, it received top scores with how it handles screen reflectivity and I have mine mounted in a bright room with huge windows opposite the TV and the vibrant picture does drown out reflections where they're not distracting. When it's off, you will see lots of reflections just because it's a black glossy screen.
Also, I had an LED TV prior, and this OLED is def bright enough even in my bright room with lots of sunny windows.
