Our Verdict
Toshiba C350 Series 2021
Amazon Fire TV 4-Series
The Amazon Fire TV 4-Series and the Toshiba C350 Fire TV 2021 use different panel technologies, each with strengths and weaknesses. The Amazon TV has much better contrast, so it's a better choice for a dark room. The Toshiba TV has wide viewing angles, but it's not a good choice for a bright room, as it can't overcome glare.
