LG C5 77-inch OLED evo 4K Smart TV vs Samsung S90C OLED TV

The LG C5 is the stronger all-round TV for most people. It runs at 144Hz with four HDMI 2.1 ports, adds Dolby Vision and DTS, and its Alpha 9 Gen8 processor handles HDR and upscaling well. The Samsung S90C is a solid QD-OLED with punchier color and Dolby Atmos, but it lacks Dolby Vision and DTS and tops out at 120Hz. Owners rate the LG higher, and the LG bundle adds a multi-year protection plan.

  • Choose the LG C5 if you want the best gaming feature set, Dolby Vision, and a larger 77-inch panel with extended coverage.
  • Choose the Samsung S90C if you prefer QD-OLED color brightness and Dolby Atmos and do not need Dolby Vision or 144Hz.

What reviewers say

LG C5 77-inch OLED evo 4K Smart TV

  • 4.9 / 52,240 ratings

Owners rate the C5 very highly, at 4.9 out of 5 from 2,240 ratings. They praise the deep blacks, the smooth 144Hz motion and the gaming features. The main complaints are brightness in bright rooms and the size and weight of a 77-inch set.

What people mention
  • Picture qualityPraisedOwners call the contrast and black levels excellent, especially in dark rooms.
  • Motion and gamingPraisedThe 144Hz panel and VRR are cited for smooth games and sports.
  • BrightnessMixedSome say highlights are strong, while others find the set dim in bright rooms.
  • Setup and sizeCriticisedThe 77-inch panel is heavy and needs two people to mount or move.

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.

What people mention
  • Picture qualityPraisedOwners describe deep blacks and vivid, bright colors, especially in HDR.
  • GamingPraisedReviewers note low lag and 4K at 120 Hz on the HDMI 2.1 ports.
  • HDR formatsCriticisedReviewers fault the lack of Dolby Vision, leaving HDR10+ and HDR10 as the options.
  • SoundMixedBuilt-in speakers are called adequate, and the missing DTS support limits some disc and streaming audio.

Questions and answers

Which is better for gaming, the LG C5 or the Samsung S90C?
The LG C5. It runs at 144Hz, has four HDMI 2.1 ports, and supports VRR and Dolby Vision gaming. The S90C is capped at 120Hz.
Does the Samsung S90C support Dolby Vision?
No. It supports HDR10+ and HDR10 but not Dolby Vision. The LG C5 supports Dolby Vision.
Which has better picture quality?
The S90C has brighter, more saturated color from its QD-OLED panel. The C5 has deeper blacks and more accurate tone mapping in dark scenes. Most viewers will be happy with either.
Is the LG C5 worth stepping up to over the S90C?
Yes if you game at high frame rates, watch Dolby Vision content, or want the longer protection plan. If you mainly watch movies in a bright room, the S90C's extra color brightness is a fair trade.
Which lasts longer?
Both use OLED panels with similar lifespans. The LG bundle adds a multi-year protection plan, which gives it an edge on long-term coverage.
Do either support DTS sound?
Only the LG C5. The S90C lacks DTS, so DTS discs will play in stereo or need a compatible soundbar.
