LG 83" C6 Series 4K OLED TV vs Samsung S90H 83" OLED 4K TV

Both are 83-inch OLEDs with 4K, Dolby Atmos and gaming features, so the split comes down to brightness, gaming headroom and platform. The LG C6 uses OLED evo with the Alpha 11 Gen3 chip, four HDMI 2.1 ports and VRR up to 165Hz, and owners rate it 4.8 out of 5. The Samsung S90H adds a glare-free coating, HDR10+ and a bundled multi-year protection plan, but its listed refresh tops out at 120Hz. Buy the LG for the brightest picture and the most gaming flexibility; buy the Samsung if glare in a bright room is your main worry or you want the longer coverage.

  • Choose the LG C6 if you want the brighter OLED evo panel, four HDMI 2.1 inputs and VRR up to 165Hz for PC and console gaming.
  • Choose the Samsung S90H if glare-free viewing in a bright room matters most, or you want the included multi-year protection plan.

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.

Questions and answers

Which is better for a bright living room?
The Samsung S90H, because of its glare-free coating. The LG C6 is the brighter OLED evo panel, but it has a standard glossy finish, so reflections are more visible in a sunlit room.
Which is better for gaming?
The LG C6. It has four HDMI 2.1 ports, a 0.1ms response time and VRR up to 165Hz. The Samsung lists 120Hz with FreeSync Premium Pro and G-SYNC, which is still strong but has less headroom.
Does either support Dolby Vision?
Only the LG C6. It supports Dolby Vision, HDR10 and HLG. The Samsung S90H uses HDR10+ and OLED HDR+ instead, so Dolby Vision content plays in a fallback format on it.
Which lasts longer?
Both are OLED panels with similar expected lifespans. The Samsung bundle includes a multi-year protection plan on top of the 1-year manufacturer warranty, so coverage lasts longer even if the hardware is comparable.
Is the Samsung worth stepping up to over the LG?
Only if glare or coverage decides it for you. The LG wins on brightness, HDMI 2.1 and refresh headroom; the Samsung wins on anti-glare, HDR10+ and the included protection plan.
Do both handle sound well without a soundbar?
Both support Dolby Atmos. The Samsung adds OTS Lite, Q-Symphony and 360 Audio for use with Samsung soundbars. The LG relies on its processor's virtual surround, so a soundbar helps either set.
