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

Both are 83-inch 4K OLEDs with four HDMI 2.1 ports and 165Hz gaming, so the split comes down to panel and platform. The Samsung S90H uses a QD-OLED panel with a Glare Free coating and Tizen, and owners rate it very highly for punchy color and bright rooms. The LG C6 uses OLED evo with Dolby Vision and Dolby Atmos, runs webOS, and has the longer track record of C-series owners praising its film handling. Buy the Samsung for a bright room and gaming, the LG for Dolby Vision movies and webOS.

  • Choose the Samsung S90H if your room gets a lot of daylight, you want glare-free QD-OLED color, and you game on PC or console at high refresh rates.
  • Choose the LG C6 if you watch a lot of Dolby Vision movies and want Dolby Atmos, webOS and the C-series track record.

Questions and answers

Which is better for a bright living room?
The Samsung S90H. Its Glare Free coating and QD-OLED brightness keep reflections and washout down in daylight. The LG C6 is brighter than older C-series sets but still uses a standard anti-glare finish.
Which handles movies better?
The LG C6 for Dolby Vision titles, since the Samsung lacks Dolby Vision entirely. The Samsung counters with HDR10+ and punchier QD-OLED color. If your library is mostly Dolby Vision, the LG is the safer pick.
Which is better for gaming?
The Samsung S90H. It reaches 165Hz natively and carries both G-SYNC and FreeSync Premium. The LG C6 has a 120Hz native panel with VRR up to 165Hz, plus a very low 0.1ms response time.
Is the LG C6 worth stepping up to over the Samsung?
Only if Dolby Vision, Dolby Atmos or webOS matter to you. Otherwise the two are close on size, resolution and HDMI 2.1, and the Samsung wins on glare handling and gaming features.
Which has better sound out of the box?
The LG C6, which supports Dolby Atmos. The Samsung has 40W speakers but no Atmos decoding. Either way, a soundbar improves both.
Do both support 4K at 120Hz on all HDMI ports?
Both have four HDMI 2.1 inputs, so both handle 4K at high refresh rates across ports. The Samsung goes further with a native 165Hz panel.
