Samsung QN48S90HA OLED 4K TV vs LG C5 48" OLED evo TV

Both are 48-inch 4K OLEDs with four HDMI ports, so the picture quality gap is small. The Samsung S90H is the newer 2026 set with a 165Hz panel, Glare Free coating, Wi-Fi 6E and a bundled surge protector, which makes it the stronger pick for gamers and bright rooms. The LG C5 is the safer, well-proven choice: evo panel, 120Hz, webOS and a long track record of solid reviews. Buy the Samsung for gaming features and glare handling; buy the LG if you want the mature, widely reviewed option.

  • Choose the Samsung S90H if you game at high frame rates, have a bright room, or want the newer panel and Wi-Fi 6E.
  • Choose the LG C5 if you want a proven OLED with webOS and don't need 165Hz or the anti-glare coating.

What reviewers say

Samsung QN48S90HA OLED 4K TV

Reviewers highlight the S90H as a versatile small-format OLED that excels in gaming due to its 165Hz panel and low input lag. The AI Gen3 processor is noted for improving upscaling and motion handling over previous generations.

What people mention
  • Gaming PerformancePraisedThe 165Hz refresh rate and dedicated Gaming Hub make it a top choice for console and PC players.
  • AI ProcessingPraisedThe NQ4 AI Gen3 processor effectively upscales lower-resolution content to 4K.
  • BrightnessMixedWhile it features an anti-glare coating, it still struggles against direct sunlight compared to high-end LCD TVs.

LG C5 48" OLED evo TV

Reviewers and owners praise the C5's contrast, motion handling and gaming features, and many call it the best small OLED for the money. Complaints center on brightness in bright rooms and on the sound from the built-in speakers.

What people mention
  • Picture qualityPraisedOwners describe deep blacks and rich color as a clear step up from their old LCD sets.
  • BrightnessMixedReviewers say it is bright enough for most rooms but dimmer than top Mini LED rivals in daylight.
  • GamingPraisedPlayers report low lag and smooth 120 Hz play on PS5 and Xbox.
  • SoundCriticisedOwners find the built-in speakers thin and often add a soundbar.

Questions and answers

Which is better for gaming?
The Samsung S90H. Its 165Hz panel, FreeSync Premium, G-Sync and Game Bar give it more headroom for high frame rates. The LG C5 is still a strong 120Hz gaming set.
Is the Samsung worth stepping up to over the LG?
If you play fast games or watch in a bright room, yes. The glare-free coating and 165Hz panel are real advantages. Otherwise the LG C5 covers the same OLED basics.
Which handles bright rooms better?
The Samsung, thanks to its Glare Free coating. The LG C5 uses a standard glossy finish, so window reflections are more visible.
Do both support Dolby Atmos?
Yes. Both list Dolby Atmos, and both use their own sound processing to widen the effect. Neither replaces a soundbar for real bass.
Which lasts longer?
Too early to say for the Samsung, which is a 2026 model. LG's C-series has years of owner reports behind it, so it carries less unknown risk.
Do both have four HDMI ports?
Yes, both list four HDMI inputs, enough for a console, a streaming box and a soundbar.
