- Brighter picture than the prior C-series
- Solid all-round OLED performance for the price
- Wi-Fi performance is a step backward from the predecessor
Samsung S90H 4K OLED Vision AI Smart TV
With 4.8 out of 5 from 1,400 ratings, owners rate the S90H highly, and the Glare Free coating is the feature most often singled out for bright rooms.
- Deep blacks and strong contrast typical of OLED
- Glare Free coating handles windows and lamps well
- Clean motion for sports and games
Questions and answers
- Which is better for a bright living room?
- The Samsung S90H, because of its Glare Free coating. The LG C6 has no anti-glare layer listed, so window light and lamps will reflect more.
- Which is better for movies?
- The LG C6. It supports Dolby Vision and Dolby Atmos on a 65-inch panel, which suits dark-room film watching better than the 42-inch Samsung.
- Which is better for gaming?
- The Samsung S90H on paper, with gaming up to 165 Hz, Motion Xcelerator and G-SYNC compatibility. The LG C6 does 120 Hz with VRR and four HDMI inputs, which is still strong.
- Is the LG C6 worth the extra money?
- Yes if you want a 65-inch screen with Dolby Vision. At $1,399.99 versus $1,197.99 as of November 4, 2026, the gap is about $202 for 23 more inches of screen.
- Which lasts longer?
- Neither maker publishes a lifespan figure. Both are OLED panels, so burn-in risk depends on how you use them; vary content and avoid static logos for hours.
- Which is better for a small bedroom?
- The Samsung S90H. A 42-inch screen fits a bedroom wall or dresser better than a 65-inch LG C6.
