How does the S85F differ from the S90F?

The S90F uses a QD-OLED panel with a quantum-dot layer, which adds color brightness and volume. The S85F uses a standard OLED panel, so it gives the same true black and contrast but less color punch in bright scenes.

Is OLED brightness enough for a bright room?

OLED brightness is lower than most LED and QLED sets, and the S85F is dimmer than Samsung's QD-OLED models. It looks best in a room where you can control the light, especially for dark movies.

Is a 77-inch screen too big for my room?

At 77 inches it suits rooms with roughly 8 to 12 feet of viewing distance. It is a good step up from 65 inches without going to the 83-inch class.

Does it support 4K and high frame rates?

Yes, it is a 4K panel, and Samsung's S85F line supports high frame rates for gaming and sports. Check the port list for the HDMI version you need.

Should I worry about burn-in?

OLED pixels can retain a static image over long periods, such as news tickers or game HUDs. Vary content and use the TV's screen-care features to lower the risk.
