Sony Z9D vs Sony Z9F

The Sony Z9F is better than the Sony Z9D, unless you watch movies in the dark from directly in front. The Z9F is much brighter in SDR, and a bit brighter in HDR. The 2018 Z9F has much better motion handling, with significantly faster response time and less input lag, great for gaming. The Z9F also has faster smart features, running a newer version of the Android TV operating system. The Z9D is a bit better in a dark room, as it has a better contrast ratio and better local dimming feature, but the image degrades rapidly when viewed at an angle.
