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

Both are 4K OLEDs with 4.8-star ratings, so the split is about size, brightness handling and gaming. The LG C6 is the stronger all-round pick for movies and console gaming: four HDMI 2.1 ports, Dolby Vision, G-Sync and FreeSync Premium, and a 165Hz panel. The Samsung S90H counters with a Glare Free coating that holds up better in rooms with windows, and its 42-inch size fits small spaces the C6's larger sizes don't. Owners of both praise black levels and contrast; the LG's webOS is generally seen as the more polished platform.

  • Choose the LG C6 if you want Dolby Vision, four full HDMI 2.1 ports and the widest gaming feature set on a 65-inch OLED.
  • Choose the Samsung S90H if your room gets a lot of daylight and you need the Glare Free coating, or you want a smaller 42-inch OLED.

Questions and answers

Which is better for a bright living room?
The Samsung S90H. Its Glare Free coating cuts reflections from windows and lamps, which is the main weakness of OLED in daylight. The LG C6 is brighter than older OLEDs but still shows reflections in a sunlit room.
Which is better for PS5 and Xbox gaming?
They are close. Both run 165Hz with G-Sync and FreeSync, and both have four HDMI ports. The LG C6 is the safer pick because all four ports are HDMI 2.1, so you can plug in multiple consoles without hunting for the right input.
Do I lose much by giving up Dolby Vision on the Samsung?
Some. Netflix, Disney+ and HBO lean on Dolby Vision, and the LG C6 renders those titles with more precise highlights. The S90H's Auto HDR Remastering still makes standard content look punchy, so the gap is visible mainly in side-by-side viewing.
Which lasts longer?
Neither has a clear edge on lifespan. Both use OLED panels with similar burn-in risk, so varied content and avoiding a static logo or ticker for hours matter more than the brand. The LG's larger size range includes the same panel generation across sizes.
Is the Samsung worth stepping up to from a cheaper OLED?
Yes if glare is your problem. The Glare Free coating is the feature that separates the S90H from budget OLEDs, and it is the first S90 series to get it. If your room is dark, the LG C6 gives you more for the same tier.
Which has better sound without a soundbar?
The Samsung S90H, slightly. Object Tracking Sound Lite follows action on screen and adds a virtual top channel. The LG C6 supports Dolby Atmos but relies on the panel's built-in speakers, so a soundbar helps either set.
