LG B5 OLED TV vs Samsung S84H OLED 4K Smart TV (65")

Both are 65-inch 4K OLEDs at 120 Hz, so the picture fundamentals are close. The LG B5 wins on size range and format support: it comes in 48 to 83 inches and handles Dolby Vision, which the Samsung S84H does not. The Samsung S84H wins on connectivity and gaming inputs: Wi-Fi 6E, Bluetooth 5.3 and four HDMI ports, one with eARC. Owners of both praise OLED contrast and viewing angles; the common complaints are brightness in bright rooms and burn-in risk with static content. Buy the LG if you want a smaller or larger size or watch Dolby Vision content. Buy the Samsung if you have several consoles and devices to plug in.

  • Choose the LG B5 if you want Dolby Vision, a size other than 65 inches, or the webOS app layout.
  • Choose the Samsung S84H if you need four HDMI ports, Wi-Fi 6E, or AirPlay from Apple devices.

What reviewers say

Samsung S84H OLED 4K Smart TV (65")

Owners of Samsung's OLED line consistently praise the contrast, the anti-glare coating and the gaming features, and call Tizen fast and well stocked. The recurring complaints are the missing Dolby Vision and the modest built-in audio.

What people mention
  • Picture qualityPraisedOwners call the contrast and color depth the main reason to buy, especially for dark-room movies.
  • GamingPraisedReviewers report low input lag and smooth 120 Hz play on current consoles.
  • Dolby VisionCriticisedBuyers note that Dolby Vision content plays in HDR10 instead, a gap next to LG and Sony OLEDs.
  • SoundCriticisedThe built-in speakers are described as thin, with most owners adding a soundbar.

Questions and answers

Which is better for a bright living room?
Neither is a bright-room standout; OLED panels trade peak brightness for contrast. The Samsung's anti-glare coating and HDR10+ tone mapping help a little with reflections, but a bright room favors a mini-LED set over either.
Which has better gaming features?
The Samsung S84H, mainly because of its four HDMI ports, so a console, soundbar and streaming box can stay connected. Both run at 120 Hz, so motion is similar.
Does the LG B5 support Dolby Vision?
Yes. The LG B5 handles Dolby Vision, HDR10 and HLG. The Samsung S84H supports HDR10+ and HLG but not Dolby Vision, which matters if you watch Dolby Vision movies and shows.
Which lasts longer?
Both use OLED panels with similar burn-in risk, so lifespan depends on viewing habits. Avoid leaving static logos or tickers on for hours, and enable the screen-shift and pixel-refresh settings on either set.
Is the Samsung S84H worth stepping up to over the LG B5?
Only if you need four HDMI inputs, Wi-Fi 6E or AirPlay. If you want Dolby Vision or a size other than 65 inches, the LG B5 is the better fit.
Which is better for a soundbar?
The Samsung S84H, because one of its four HDMI ports supports eARC, which passes lossless audio to a soundbar. The LG B5 also supports eARC, but with fewer ports you have less room for other devices.
