LG C5 OLED evo 4K Smart TV (2025)

Questions and answers
- Which is better for gaming?
- The Samsung S90H, on paper: 165Hz versus 120Hz native, and HDR10+ Gaming. The LG C5 still covers 4K 120Hz, VRR, ALLM and a 0.1ms response time, which is enough for most console players.
- Does the LG C5 have Dolby Vision and the Samsung not?
- Yes. The C5 supports Dolby Vision and Dolby Atmos. The S90H lists HDR10, HDR10+ and HLG but no Dolby Vision, so Dolby Vision content plays in HDR10.
- Which has better sound?
- The LG C5, slightly. Both output 40W, but the C5 uses a 2.2-channel system versus the S90H's 2.1. A soundbar improves either.
- Is the Samsung S90H worth the extra money?
- Only if you need 165Hz or HDR10+ Gaming. At $1,397.99 at Amazon as of November 3, 2026, it is close to C5 pricing, so compare the C5's current price first.
- Which lasts longer?
- Neither maker publishes an OLED lifespan figure. The C5's 2,339 ratings at 4.8 are stronger evidence than the S90H's 33 ratings at 4.9, but both are OLED and both can show burn-in with static content.
- Which is better in a bright room?
- The LG C5, which LG says has boosted brightness for well-lit rooms. The S90H counters with a Glare Free coating, which cuts reflections but does not raise peak brightness.
