Samsung S90F OLED TV vs LG OLED evo C4 65-Inch TV

Both are 65-inch 4K OLEDs with excellent contrast and wide viewing angles, and owners rate them about equally. The Samsung S90F is the better pick for gamers and bright rooms: it runs 144Hz over four HDMI 2.1 ports and measured around 1,160 nits on a 10% HDR window, well above typical OLED output. The LG C4 is the better pick for movie watchers: it supports Dolby Vision and Dolby Atmos, which the Samsung lacks, and its webOS Re:New program covers five years of updates. Reviewers praise both for color and contrast; the S90F's recurring complaints are its panel coating and a Game mode that needed a USB update to restore.

  • Choose the Samsung S90F if you play at high frame rates on a PC or console and want the brightest HDR highlights of the two.
  • Choose the LG C4 if you watch a lot of Dolby Vision movies and want a TV that keeps getting software updates for years.

What reviewers say

Samsung S90F OLED TV

  • 4.6 / 5Google Shopping · 2,700 ratings

Reviewers and owners consistently praise the S90F's picture: vivid color, deep contrast and brightness that impresses people coming from LED sets. Gamers like the fast motion and low input lag, and setup is called quick. Complaints center on the reflective panel coating and a Game mode that needed a USB update to restore.

What people mention
  • Picture qualityPraisedOwners and reviewers call the color vivid and the contrast deep, especially against older LED TVs.
  • GamingMixedLow input lag and fast motion are praised, but some units needed a USB update to restore Game mode.
  • Panel coatingCriticisedThe glossy finish reflects room light, and at least one owner called the coating awful.
  • BrightnessPraisedHDR highlights are bright enough that upgraders notice the jump from LED sets.
A reviewer's verdict
  • CNET

    The Samsung S90F boasts excellent image quality and fast motion for gamers, but it is expensive and lacks the step-up model's glare-free coating.

Questions and answers

Which is better for gaming, the S90F or the C4?
The S90F has the edge on paper: 144Hz versus 120Hz, with four HDMI 2.1 ports on both. The C4 counters with G-Sync VRR certification and a 0.1 ms response time. Competitive players will notice the extra frame rate; most console players will not.
Does the Samsung S90F support Dolby Vision?
No. It handles HDR10, HDR10+ and HLG. The LG C4 supports Dolby Vision, so Dolby Vision discs and streams look their best on the LG.
Which one is brighter?
The S90F is rated around 1,162 nits on a 10% HDR window, which is high for OLED. LG does not publish a comparable figure for the C4, only its Brightness Booster technology. In practice the Samsung should produce stronger small highlights.
Which lasts longer?
Neither has a documented lifespan advantage. The LG's five years of webOS updates keep its software current longer. OLED panels in both can dim over many years of static content, so mixed viewing helps either set.
Is the step up to the S90F worth it over the C4?
If you game at high frame rates or watch in a bright room, yes. If Dolby Vision movies and long software support matter more, the C4 is the better fit and you give up little in picture quality.
Do either of these handle glare well?
Neither has a strong anti-glare coating. The S90F's coating is a common complaint, and the C4 lists no anti-glare treatment. In a bright room, plan on curtains or careful placement for both.
