Samsung S84D OLED 4K Smart TV vs LG G6 OLED evo 4K Smart TV

The LG G6 is the stronger TV on picture and gaming: its OLED evo panel with Brightness Booster Ultra is brighter than the Samsung S84D, it adds Dolby Vision, and it supports higher frame rates with G-Sync and FreeSync Premium. The Samsung S84D is a solid OLED with 120Hz, four HDMI ports and full Alexa and Google Assistant support, but it lacks Dolby Vision and its panel is dimmer. Buy the LG if you watch a lot of HDR movies or play games on a console or PC. Buy the Samsung if you want a mainstream OLED and prefer Google Assistant built in.

  • Choose the Samsung S84D if you want a well-rounded 77-inch OLED with Google Assistant and Alexa built in and you don't need Dolby Vision.
  • Choose the LG G6 if you want the brighter OLED picture, Dolby Vision, and the best gaming features at this size.

What reviewers say

Samsung S84D OLED 4K Smart TV

Owners of Samsung's OLED sets praise the contrast, motion and design, and most find the picture a clear step up from LED. Common complaints are brightness in bright rooms and the lack of Dolby Vision.

What people mention
  • Picture qualityPraisedOwners say the OLED panel gives deep blacks and rich contrast that LED sets cannot match.
  • BrightnessCriticisedReviewers note it dims next to QD-OLED and Mini-LED rivals in a bright room.
  • MotionPraisedThe 120 Hz panel is described as smooth for sports and fast action.
  • Dolby VisionCriticisedBuyers miss Dolby Vision, since the set handles HDR10 and HDR10+ only.

Questions and answers

Which is better for gaming, the Samsung S84D or the LG G6?
The LG G6. It supports up to 165Hz, 0.1ms response, VRR, G-Sync and FreeSync Premium. The Samsung S84D tops out at 120Hz with no listed VRR support.
Does the Samsung S84D support Dolby Vision?
No. It handles HDR10 and HLG. The LG G6 adds Dolby Vision, which matters for Dolby Vision movies and shows.
Which TV is brighter in a bright room?
The LG G6. Its Brightness Booster Ultra panel is rated up to 3.9x brighter than conventional OLED, and its Reflection Free coating reduces glare. The Samsung S84D uses a standard OLED panel.
Is the LG G6 worth stepping up to over the Samsung S84D?
Yes if you care about HDR movies or gaming. You get Dolby Vision, a brighter panel, higher frame rates and sync tech. The Samsung is the simpler pick if you mainly want Google Assistant built in.
Can I put either TV on a stand?
The LG G6 ships with a wall mount and no stand, so you need to wall-mount it or buy a stand separately. The Samsung S84D is a flat panel that works with standard TV stands.
Do both TVs have 120Hz or higher refresh?
Both list 120Hz. The LG G6 goes higher, up to 165Hz, which benefits fast games on a capable console or PC.
