Our take on the Samsung Class S84D Series 77" 4K Ultra HDR Smart OLED Tizen TV

The Samsung S84D is a 77-inch 4K OLED TV running the Tizen smart platform with HDR10 support. OLED panels deliver per-pixel light control, so blacks are true black and contrast is very high, which suits dark-room movie watching. It sits below Samsung's flagship OLEDs, so it skips the brightest panel and the anti-glare coating those models carry. Buyers pick it for a big-screen OLED with Samsung's app and gaming features rather than for peak brightness.

What reviewers say

Owners of Samsung's S84D-class OLEDs praise the picture in dark rooms, the tidy Tizen interface and the gaming features. Common complaints are lower brightness than QD-OLED rivals and reflections in bright rooms.

What people mention
  • Picture qualityPraisedOwners say blacks are deep and contrast is excellent, especially for movies at night.
  • BrightnessCriticisedViewers in bright rooms find it dimmer than QD-OLED and Mini-LED rivals.
  • ReflectionsCriticisedThe glossy screen shows window and lamp reflections during daytime viewing.

Questions and answers

Is the S84D good for bright rooms?
It is best in dim or dark rooms. Peak brightness is lower than Samsung's QD-OLED sets and the screen is glossy, so daytime reflections are visible.
Does it support Dolby Vision?
No. It handles HDR10, so Dolby Vision content plays in standard HDR instead.
Is it good for gaming?
Yes. It has HDMI 2.1 inputs, low input lag and gaming settings in Tizen, and OLED motion is clean.
Should I worry about burn-in?
OLED can retain static images over long periods. Vary content and avoid leaving news tickers or game HUDs on for hours.
Do I need a soundbar?
For movies, yes. The built-in speakers are fine for everyday TV but lack bass and scale.
How does it compare with Samsung's S95D?
The S95D uses a brighter QD-OLED panel with an anti-glare coating. The S84D trades some brightness and glare handling for the same OLED contrast and Tizen platform.
