Common questions

Before you buy

Is the Samsung 77 S99H Samsung's brightest OLED?

It uses OLED HDR Pro, described as Samsung's brightest OLED panel, so HDR highlights punch hard while the self-lit pixels keep blacks perfect.

Does it support Dolby Vision?

No. Samsung uses HDR10+ instead of Dolby Vision, so Dolby Vision content falls back to standard HDR. Both are dynamic HDR formats.

How is the S99H different from the S93D?

The S99H is the brighter, higher-tier model with a 165Hz panel and FloatLayer design, while the S93D is a slightly more affordable 144Hz OLED.

How big a room do I need?

A 77 inch screen suits rooms where you can sit roughly three metres or more back, so it is best in a larger living room or dedicated space.
