LG C2 77-Inch OLED evo TV vs Samsung S90D 77" OLED TV

Both are 77-inch 4K OLEDs with 120 Hz-plus panels, four HDMI 2.1 ports and strong gaming features. The LG C2 is the safer all-round pick: it has been on the market longer, is widely praised for out-of-box accuracy and webOS, and its four full-bandwidth HDMI 2.1 ports suit PS5 and Xbox owners. The Samsung S90D uses a QD-OLED panel that reviewers say pushes brighter, more saturated color, and it adds a 144 Hz refresh rate and FreeSync Premium Pro. Owners of both report excellent picture quality; the C2 is the more proven, better-documented set, while the S90D is the brighter, more gaming-forward one.

  • Choose the LG C2 if you want the proven set with four full-bandwidth HDMI 2.1 ports, Dolby Vision support and a mature smart platform.
  • Choose the Samsung S90D if you want a brighter QD-OLED picture, a 144 Hz panel and FreeSync Premium Pro for PC and console gaming.

What reviewers say

LG C2 77-Inch OLED evo TV

Reviewers and owners consistently rate the C2's picture quality and gaming features very highly. Most criticism centers on brightness in bright rooms and the usual OLED caution about static logos.

What people mention
  • Picture qualityPraisedOwners call the contrast and color the main reason to buy, especially in dark rooms.
  • GamingPraisedReviewers highlight low lag, 120 Hz and four HDMI 2.1 ports for consoles.
  • BrightnessMixedFine in dim rooms, but reviewers say HDR highlights and daytime viewing trail brighter LCD and QD-OLED sets.
  • ReflectionsCriticisedThe glossy anti-reflective coating still shows windows and lamps in bright rooms.

Questions and answers

Which is better for gaming, the LG C2 or the Samsung S90D?
The S90D edges ahead on paper with 144 Hz and FreeSync Premium Pro. The C2 matches it on four HDMI 2.1 ports and adds G-Sync support, so console players will be happy with either.
Does the Samsung S90D support Dolby Vision?
No. It supports HDR10, HLG and HDR10+. If Dolby Vision matters for your streaming or disc library, the LG C2 is the one that has it.
Which has the better picture?
The S90D is brighter with more saturated color thanks to QD-OLED. The C2 is very accurate out of the box and handles dark scenes well. Most viewers would call both excellent.
Is the LG C2 worth stepping up to over the S90D?
Only if Dolby Vision or the proven webOS platform matters to you. Otherwise the S90D offers more brightness and a faster panel for similar money.
Which lasts longer?
Both use self-lit OLED panels with similar burn-in risk. Neither has a clear durability edge; vary content and avoid static logos for long stretches on either.
Do both have four HDMI 2.1 ports?
Yes. Both offer four HDMI 2.1 inputs, enough for a current console, a PC and a soundbar over eARC.
