LG OLED42C6PUA 42" OLED evo C6 vs Samsung S90C OLED TV

Buy the LG C6 if you want a smaller 42-inch OLED with Dolby Vision, four HDMI 2.1 ports and the latest webOS. Buy the Samsung S90C if you want a 65-inch QD-OLED with stronger color volume and a brighter picture for a big living room. The LG wins on format support and gaming features; the Samsung wins on size and punch. Owners of both praise the contrast and design, and reviewers knock the Samsung for skipping Dolby Vision.

  • Choose the LG C6 if you sit close, game at high refresh rates, or want Dolby Vision and four full-bandwidth HDMI ports in a 42-inch set.
  • Choose the Samsung S90C if you want a 65-inch QD-OLED for a bright room and don't need Dolby Vision.

Samsung S90C OLED TV

  • 4.6 / 5964 ratings

Reviewers rate the S90C highly for its bright QD-OLED picture and gaming features. Most criticism centers on the missing Dolby Vision and DTS support and on reflections in bright rooms.

  • Picture qualityPraisedOwners describe deep blacks and vivid, bright colors, especially in HDR.

Questions and answers

Which is better for gaming?
The LG C6. It has four HDMI 2.1 ports, VRR up to 165Hz, 0.1ms response and both G-Sync and FreeSync Premium. The S90C is a solid 120Hz gaming set but has fewer high-bandwidth ports.
Does the Samsung S90C support Dolby Vision?
No. It supports HDR10+ and HLG instead. If Dolby Vision matters for your streaming library, the LG C6 is the one to pick.
Which has better picture quality?
The S90C has richer color volume and more brightness thanks to QD-OLED. The C6 has perfect blacks and Dolby Vision, so it wins on format accuracy. Both are excellent; the room and size decide it.
Is the 42-inch LG too small for a living room?
For most living rooms, yes. A 42-inch set suits a bedroom, desk or small apartment. The 65-inch S90C is the better fit for a main viewing room.
Which lasts longer?
Both use OLED panels with similar lifespans. LG adds OLED Care features that dim static logos and refresh pixels. Neither is immune to burn-in if you leave news tickers or game HUDs on for hours daily.
Is the S90C worth stepping up to over the C6?
If you want a big screen and brighter color, yes. If you want Dolby Vision, four HDMI 2.1 ports and a smaller footprint, the C6 is the better fit.
