There's a discussion going on between whether dynamic mode or movie mode is the best for TV watching. Scott says that dynamic mode doesn't show content in the manner the creator intended, while movie mode gets you a lot closer to that. Leo says he tried it for a week and it was just way too bright. It also causes a loss in detail to watch in dynamic mode and Scott says that bright spots (called blooming) will begin to appear and if you're using an OLED screen, you'll wear it out faster. Another thing that can help is a bias light behind your TV. It helps for less eye fatigue.
Paul has limited vision and wants to know if there's a TV that's friendly to the blind. He wants to be able to Dim the screen because it's too bright to see details. Leo says to change it to Movie Mode in the settings and that will help. His TV is only 42", and Leo advises at least 55" for watching from 10' away.
