LG 83" C6 Series 4K OLED TV vs Samsung QN83S90HA 83-inch OLED TV

Both are 83-inch 4K OLEDs with 165Hz gaming support and Dolby Atmos, but they differ in panel treatment and platform. The LG C6 uses an OLED evo panel with a claimed 3x brightness boost, four HDMI 2.1 ports, and webOS 26 with 400+ free channels. The Samsung S90H adds a glare-free coating, HDR10+ support, and Tizen's Gaming Hub with cloud gaming. Reviewers and owners consistently praise OLED contrast on both; the LG is the safer pick for mixed lighting and PC gaming, while the Samsung suits bright rooms and Samsung ecosystem users.

  • Choose the LG C6 if you want four HDMI 2.1 inputs, Dolby Vision, and the brightest OLED evo panel LG has put in its C-series.
  • Choose the Samsung S90H if glare is a problem in your room, you want HDR10+ and cloud gaming built in, or you already use Samsung phones and soundbars.

What reviewers say

LG 83" C6 Series 4K OLED TV

  • 4.8 / 5923 ratings

Owners and critics highly rate the C6 for its balance of gaming features and cinematic accuracy, specifically noting the improved brightness over the C4 and C5 models.

What people mention
  • BrightnessPraisedUsers report the panel is significantly brighter than previous OLEDs, performing well even in rooms with windows.
  • Gaming PerformancePraisedThe 165Hz refresh rate and VRR support provide a tear-free experience for high-end PC rigs.
  • DesignPraisedThe nearly invisible bezel and slim profile make it a standout aesthetic piece.
  • Sound QualityMixedWhile Dolby Atmos processing is good, many users recommend a dedicated soundbar for better impact.

Samsung QN83S90HA 83-inch OLED TV

  • 4.8 / 5257 ratings

Reviewers and owners praise the QN83S90HA for its effective glare-free screen, deep blacks, and gaming performance. They criticise its brightness compared to Mini-LED rivals and note the risk of burn-in with static logos.

What people mention
  • GlarePraisedOwners say the Glare Free screen handles window reflections better than glossy OLEDs.
  • BrightnessMixedReviewers find it bright enough for most rooms but not as punchy as the brightest Mini-LED TVs.
  • GamingPraisedGamers highlight the 165Hz refresh rate and VRR support for smooth, tear-free play.
  • Burn-inCriticised

Questions and answers

Which is better for a bright living room?
The Samsung S90H has a Glare Free coating that reduces reflections, which helps in rooms with windows opposite the TV. The LG C6 is brighter than earlier C-series but still has a glossy screen, so reflections are more visible.
Which has better gaming features?
Both reach 165Hz with VRR. The LG C6 gives you four full HDMI 2.1 ports, which matters if you connect a PS5, Xbox and PC at once. The Samsung adds FreeSync Premium Pro, G-SYNC and a Gaming Hub with cloud gaming.
Does the Samsung support Dolby Vision?
No. Samsung backs HDR10+ instead. The LG C6 supports Dolby Vision, HDR10 and HLG. If your streaming library is heavy on Dolby Vision titles, the LG is the better match.
Which is better for sound without a soundbar?
The Samsung S90H has OTS Lite, Q-Symphony and a bundled Picture Frame Speaker, so it offers more out of the box. The LG C6 has Dolby Atmos but standard built-in speakers; most owners add a soundbar.
Is the LG C6 worth stepping up to over the Samsung?
Step up to the LG if you need four HDMI 2.1 ports, Dolby Vision, or the brighter OLED evo panel. Stay with the Samsung if glare control, HDR10+ or Samsung ecosystem features matter more.
Which lasts longer?
Both use OLED panels with similar lifespans; neither maker publishes a rated hours figure. Burn-in risk is low for normal mixed viewing on either. The LG's evo panel is designed for higher brightness, which can matter over many years of heavy use.
