LG C5 OLED TV vs Samsung S90C 65" OLED TV

The LG C5 is the better TV of the two for most people. It has a newer α9 Gen8 processor, four HDMI 2.1 ports, 144Hz VRR with G-Sync and FreeSync, Dolby Vision and Dolby Atmos, and webOS with up to five years of updates. The Samsung S90CA is an older-generation OLED with a solid Tizen platform and a 65-inch panel, but standard OLED brightness and fewer gaming features. Reviewers rate the C5 highly for picture and value; owners praise brightness and color but report some software bugs and a jumpy remote cursor.

  • Choose the LG C5 if you want the newer panel, four HDMI 2.1 ports, 144Hz gaming with G-Sync and FreeSync, Dolby Vision, and a longer software update promise.
  • Choose the Samsung S90CA if you want a 65-inch OLED on Tizen and do not need the C5's extra gaming features or Dolby Vision.

What reviewers say

LG C5 OLED TV

  • 4.3 / 5Google Shopping · 18,299 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, the fixed stand, and software bugs with the remote and forced ads.

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 S90C 65" OLED TV

Owners and reviewers rate the S90C highly for picture quality, color and gaming features at its tier. Common complaints are brightness in bright rooms, the lack of Dolby Vision and off-angle color shift.

What people mention
  • Picture qualityPraisedOwners call the contrast and color the standout, especially in a dark room.
  • BrightnessMixedReviewers say it is bright enough for most viewing but trails the S95C and newer OLEDs in a bright room.
  • GamingPraisedFour HDMI 2.1 ports and 4K 120Hz support are repeatedly noted as a reason to buy.
  • Dolby VisionCriticisedBuyers miss Dolby Vision, since the set supports HDR10+ only.

Questions and answers

Which is better for gaming, the LG C5 or the Samsung S90CA?
The LG C5. It has four HDMI 2.1 ports, native 120Hz with VRR up to 144Hz, G-Sync and FreeSync Premium, and a 0.1ms response time. The S90CA lacks those listed gaming features.
Does the Samsung S90CA support Dolby Vision?
No. It supports HDR10 and HLG. The LG C5 adds Dolby Vision, which matters for Dolby Vision movies and shows on Netflix and Disney+.
Which has the brighter picture?
The LG C5. Its OLED evo panel with Brightness Booster is brighter than the standard OLED panel in the S90CA, which helps in a bright living room.
Is the LG C5 worth stepping up to over the S90CA?
For most buyers, yes. The C5 adds a newer processor, Dolby Vision, four HDMI 2.1 ports, 144Hz gaming and a longer update promise. Choose the S90CA only if you want a 65-inch OLED on Tizen and do not need those extras.
Which is more reliable?
Both are OLED panels with similar panel longevity. The C5 has more reported software bugs, such as ARC disconnects and app crashes, while Tizen on the S90CA is more mature and stable.
Which is better for movies?
The LG C5. Dolby Vision, Dolby Atmos and the evo panel give it the edge for movie nights, and reviewers rate its picture quality highly.
