LG G4 OLED evo 4K Smart TV vs Samsung S90D OLED 4K Smart TV

The LG G4 is the better pick for most people: its OLED evo panel with Micro Lens Array is noticeably brighter than the S90D, and it adds Dolby Vision and DTS support that Samsung omits. The S90D is a strong alternative with a matte anti-glare coating that handles bright rooms well, and Samsung's QD-OLED panel produces very saturated colors. Both run 120 Hz with four HDMI 2.1 ports, so gamers are well served either way; reviewers consistently rate the G4 higher for picture accuracy and motion, while S90D owners praise its glare handling.

  • Choose the LG G4 if you watch movies in a dim room and want Dolby Vision, DTS audio passthrough and the brightest OLED picture LG has made.
  • Choose the Samsung S90D if your room has lots of daylight and you want a matte screen that cuts reflections, or you prefer Samsung's Tizen interface.

What reviewers say

LG G4 OLED evo 4K Smart TV

  • 4.8 / 54,100 ratings

Owners rate the G4 very highly, with 4.8 out of 5 from about 4,100 ratings. Most praise the picture, especially blacks and contrast, and its gaming features. Complaints center on brightness in very bright rooms and the risk of burn-in.

What people mention
  • Picture qualityPraisedOwners say blacks are deep and colors look rich, especially in dark rooms.
  • BrightnessMixedMany find it bright enough, but some in sunny rooms want more peak brightness.
  • GamingPraisedThe 120 Hz panel and four HDMI ports are called out as great for consoles.
  • Burn-inCriticisedSome owners worry about static logos and HUDs leaving marks over time.

  • GamingPraisedReviewers note low input lag and smooth motion at 120 Hz for consoles.

Questions and answers

Which is better for a bright living room?
The S90D. Its anti-glare coating cuts window and lamp reflections that the G4's glossy panel shows. The G4 wins in a dark room where its extra brightness and Dolby Vision matter more.
Does the LG G4 support Dolby Vision?
Yes. The G4 handles Dolby Vision, HDR10 and HLG. The S90D supports HDR10+ but not Dolby Vision, which matters if you stream from services that use it.
Which is better for gaming?
They are close. Both do 120 Hz with four HDMI 2.1 ports and variable refresh rate. The G4 adds G-Sync certification and DTS audio, which helps PC players.
Is the G4 worth stepping up to over the S90D?
If you watch movies in a dark room and want Dolby Vision plus higher peak brightness, yes. If your room is bright or you mainly watch cable and sports, the S90D's matte screen is the more practical choice.
Which has better sound?
Neither has strong built-in audio. The G4 passes DTS and Dolby Atmos to a soundbar or receiver; the S90D handles Atmos only. Plan on a soundbar with either.
Do both support voice assistants?
The G4 works with Google Assistant, Alexa and Siri. The S90D supports Google Assistant and Alexa but not Siri.
