LG C3 OLED evo 77" 4K Smart TV vs Samsung S90C OLED 4K TV

Both are 4K 120Hz OLEDs with HDMI 2.1, so picture motion and gaming feel close. The LG C3 wins on format support and smart features: Dolby Vision, four full-bandwidth HDMI 2.1 ports, DTS, and all three voice assistants. The Samsung S90C wins on color volume and brightness in bright rooms thanks to its Quantum Dot layer, and it comes in 65 and 77 inches. Owners of both praise the blacks and viewing angles; LG buyers cite webOS and the Magic Remote, Samsung buyers cite the anti-glare coating and Gaming Hub.

  • Choose the LG C3 if you watch Dolby Vision content, want four full HDMI 2.1 ports for a console plus a PC, or use an iPhone and want AirPlay and Siri.
  • Choose the Samsung S90C if your room is bright, you want punchier color, or you prefer Samsung's Tizen apps and Gaming Hub.

What reviewers say

LG C3 OLED evo 77" 4K Smart TV

Owners of the C3 line praise the contrast, gaming features and webOS, and most find the 77-inch size worth the jump. Complaints center on brightness in bright rooms, reflections, and the built-in speakers.

What people mention
  • Picture qualityPraisedOwners call the contrast and black levels the main reason to buy.
  • BrightnessMixedFine in dim rooms, but some find it dimmer than expected in daylight.
  • GamingPraised120Hz, VRR and low lag are cited as strong for consoles and PC.
  • SoundCriticisedThe built-in speakers are called thin, with most owners adding a soundbar.

Samsung S90C OLED 4K TV

  • 4.5 / 51,300 ratings

Owners rate the S90C highly for its picture, especially color brightness and contrast, and gamers praise the smooth 120 Hz motion. Complaints center on sound quality and the absence of Dolby Vision.

What people mention
  • Picture qualityPraisedOwners call the QD-OLED picture vivid and bright, with strong contrast in both dark and lit rooms.
  • GamingPraisedGamers report smooth 120 Hz motion and low lag through the Gaming Hub.
  • SoundCriticisedReviewers say the built-in speakers are clear but lack bass, so a soundbar is often added.

Questions and answers

Which is better for a bright living room?
The Samsung S90C. Its QD-OLED layer and anti-glare coating hold up better with windows and daylight. The LG C3 is still an OLED, so it dims reflections less well in a very bright room.
Which is better for PS5 and Xbox Series X?
They are close. Both do 4K at 120Hz with VRR and ALLM on four HDMI 2.1 ports. The LG adds G-Sync certification and Dolby Vision gaming, which the Samsung lacks.
Do I lose much without Dolby Vision on the Samsung?
Some. Dolby Vision titles on Netflix, Disney+ and 4K Blu-ray will play in HDR10 on the S90C. The picture is still strong, but the LG renders those scenes with more precise highlights.
Which lasts longer?
Neither has a clear edge. Both use organic OLED emitters that can dim over years of static content. The Samsung's quantum dot layer is inorganic, but the light-emitting layer is still OLED. Burn-in risk is similar for both.
Is the step up to 77 inches worth it over 65?
Only the Samsung S90C comes in both sizes here; the LG C3 listed is 77 inches. At normal seating distance a 77-inch screen gives a noticeably more cinematic image, but it needs more wall space and a sturdier stand.
Which has better sound without a soundbar?
The Samsung S90C. Its 2.1.2-channel setup with Object Tracking Sound moves audio with on-screen action. The LG C3's 2.2-channel system is clear but flatter.
