LG C5 OLED TV vs Samsung S84H OLED 4K Smart TV (65")

The LG C5 is the better gaming TV: four HDMI 2.1 ports, VRR up to 144Hz, G-Sync and FreeSync Premium, and a brighter evo panel. The Samsung S84H runs at 120Hz, supports HDR10+ but not Dolby Vision, and its Tizen platform is the smoother, ad-heavier of the two. Reviewers praise the C5's picture and brightness but report software bugs and forced ads; the S84H is the calmer pick for movie nights and Samsung phone owners.

  • Choose the LG C5 if you game on a PC or console and want 144Hz, four HDMI 2.1 ports and Dolby Vision.
  • Choose the Samsung S84H if you want a 120Hz OLED with HDR10+ and tight AirPlay and SmartThings integration.

  • 4.8 / 518,000 ratings

With 4.8 out of 5 from about 18,000 ratings, owners are largely enthusiastic about the C5's picture and gaming features. They praise crisp, vivid images with deep blacks, even pixels and easy setup. The main complaints are value for money, banding in dark scenes and the fixed stand.

What people mention
  • Picture qualityPraisedOwners praise the crisp, vivid picture, rich color and perfect blacks, especially for dark-room movies.
  • BrightnessMixedMany say the high brightness makes the picture pop, but some find it less bright or colorful than competing OLEDs in well-lit rooms.
  • GamingPraisedGamers like the 144Hz VRR, low response time and four HDMI 2.1 ports.
  • ReflectionsMixedThe anti-glare coating helps, but owners still notice reflections in daylight.

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.

  • SoundCriticisedThe built-in speakers are described as thin, with most owners adding a soundbar.
