Samsung S90H OLED 4K Smart TV vs LG OLED evo C6 48" 4K Smart TV

Both are 48-inch 4K OLEDs for 2026, so the picture quality gap is small. The Samsung S90H wins on motion and gaming headroom with a 165 Hz panel, four HDMI ports and HDR10+ support. The LG C6 wins on format support and streaming apps, with Dolby Vision, Dolby Vision gaming and the full webOS app set. Buy the Samsung for fast gaming and a brighter, punchier HDR10+ picture; buy the LG if you watch a lot of Dolby Vision movies and shows.

  • Choose the Samsung S90H if you game at high frame rates or want the extra HDMI ports and HDR10+ support.
  • Choose the LG C6 if Dolby Vision content and the widest app selection matter more to you than a 165 Hz panel.

What reviewers say

Samsung S90H OLED 4K Smart TV

  • 4.9 / 5884 ratings

Owners rate the S90H very highly across 884 ratings, and the praise centers on picture quality, contrast and ease of setup. Complaints are few and mostly about sound and brightness in bright rooms.

What people mention
  • Picture qualityPraisedOwners describe deep blacks, strong contrast and rich color from the OLED panel.
  • SoundCriticisedReviewers find the two built-in speakers weak and recommend a soundbar.
  • BrightnessMixedThe picture is bright enough for most rooms but can look dim in strong daylight.
  • SetupPraisedBuyers say it is quick to set up and the Tizen menus are easy to navigate.

Questions and answers

Which is better for gaming?
The Samsung S90H has the higher 165 Hz refresh rate and one more HDMI port. The LG C6 adds FreeSync Premium and G-Sync plus Dolby Vision gaming. Pick the Samsung for raw frame rate, the LG for VRR features and Dolby Vision games.
Which has better HDR?
The LG C6 supports Dolby Vision, which most streaming movies use. The Samsung S90H supports HDR10+ instead. If you watch a lot of Dolby Vision content, the LG is the safer pick.
Do both have Dolby Atmos?
Yes, both list Dolby Atmos with two built-in speakers. Neither has the driver count for real overhead sound, so a soundbar or receiver is worth adding to either.
Which lasts longer?
Both use OLED panels with similar lifespans and both carry manufacturer warranties. OLED brightness fades gradually over years of use. Neither has a clear durability edge on paper.
Is the Samsung worth stepping up to over the LG?
Only if you game at high frame rates or need four HDMI inputs. For movie watching, the LG's Dolby Vision support is the more useful advantage.
Can I use either without a cable box?
The LG C6 has a built-in ATSC tuner for antenna channels. The Samsung listing does not show a tuner, so check before relying on an antenna with it.
