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

Both are 4K OLED TVs with 120 Hz panels and four HDMI ports, so the picture fundamentals are close. The LG B5 is the better pick for mixed movie and gaming use: it supports Dolby Vision, which the Samsung S84H does not, and its webOS is simple to learn. The Samsung S84H counters with a brighter, punchier HDR10+ presentation, Wi-Fi 6E and a cleaner Tizen interface. Owners of both praise the deep blacks and wide viewing angles; the main complaints are OLED's limited peak brightness in bright rooms and the risk of burn-in with static content.

  • Choose the LG B5 if you watch Dolby Vision movies, want the widest format support and prefer webOS.
  • Choose the Samsung S84H if you want brighter HDR highlights, Wi-Fi 6E and Samsung's Tizen app layout.

What reviewers say

LG B5 OLED TV

  • 4.7 / 54,200 ratings

With 4.7 out of 5 from about 4,200 ratings, owners are largely happy with the B5's picture and gaming features. Most praise comes from people stepping up from LED TVs. Complaints center on brightness in bright rooms and the step down from the C series.

What people mention
  • Picture qualityPraisedOwners say blacks are deep and colors look rich, especially in dim rooms.
  • BrightnessCriticisedReviewers say it struggles in bright, sunlit rooms compared with brighter OLEDs.
  • GamingPraisedBuyers like the 120Hz panel with VRR for consoles and PC.
  • ProcessorMixedSome say the Alpha 8 chip is fine, others notice weaker upscaling than the C series.

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.
Reviews
  • You can get an LG B5 OLED for less than $900

Questions and answers

Which is better for movies?
The LG B5 edges ahead because it supports Dolby Vision, which most premium streaming films use. The Samsung S84H looks excellent with HDR10+ content but cannot play Dolby Vision.
Which is better for gaming?
They are close. Both run 120 Hz with low-latency game modes and four HDMI ports. The Samsung's Wi-Fi 6E helps if you stream games, while the LG's Dolby Vision matters for console titles that support it.
Does the Samsung S84H support Dolby Vision?
No. It supports HDR10+ and HLG only. If Dolby Vision matters to you, the LG B5 is the one to pick.
Which lasts longer?
Both use OLED panels with similar lifespans. Burn-in risk depends on what you watch, not the brand. Vary content and enable screen-shift or logo-dimming settings on either set.
Is the step up to the Samsung worth it?
Only if you want Wi-Fi 6E, HDR10+ and Tizen. Otherwise the LG B5 covers more HDR formats and is the safer all-round choice.
Which has better sound?
Both rely on built-in speakers that are fine for news but thin for films. A soundbar over eARC, available on both, is the bigger upgrade than the difference between them.
