LG C5 OLED TV vs Samsung S90H OLED 4K TV

Both are 4K OLEDs with four HDMI 2.1 ports and 120Hz-plus panels, so the split comes down to brightness and glare versus gaming features and platform polish. The LG C5 adds 144Hz VRR, G-Sync and FreeSync Premium, Dolby Vision, and webOS with five years of updates, but owners report banding in dark scenes and buggy early software. The Samsung S90H counters with a Glare Free, PANTONE-validated panel that reviewers say holds up in bright rooms, plus a fast Tizen system, though it lacks Dolby Vision and has fewer ratings behind it. Buy the C5 for a dark room and serious gaming; buy the S90H for a bright room with windows and glare.

  • Choose the LG C5 if you game on PC or console and want 144Hz VRR, G-Sync, FreeSync Premium and Dolby Vision in a dark room.
  • Choose the Samsung S90H if your room has big windows or lamps and you want a glare-free OLED with a fast Tizen system.

What reviewers say

LG C5 OLED TV

  • 4.8 / 518,000 ratings

With 4.8 out of 5 from about 18,000 ratings, owners are largely enthusiastic about the C5's picture and gaming features. They praise crisp, vivid images with deep blacks, even pixels and easy setup. The main complaints are value for money, banding in dark scenes and the fixed stand.

What people mention
  • Picture qualityPraisedOwners praise the crisp, vivid picture, rich color and perfect blacks, especially for dark-room movies.
  • BrightnessMixedMany say the high brightness makes the picture pop, but some find it less bright or colorful than competing OLEDs in well-lit rooms.
  • GamingPraisedGamers like the 144Hz VRR, low response time and four HDMI 2.1 ports.
  • ReflectionsMixedThe anti-glare coating helps, but owners still notice reflections in daylight.

Questions and answers

Which is better for a bright room?
The Samsung S90H. Its Glare Free coating and anti-reflective screen are the reason reviewers say it holds up with windows and lamps. The LG C5 is bright for an OLED but owners and reviewers call it dimmer than rivals.
Which is better for gaming?
The LG C5. It reaches 144Hz over VRR, carries G-Sync and FreeSync Premium, and has a 0.1ms response time. The S90H has four HDMI 2.1 ports and VRR at 120Hz but no listed G-Sync or FreeSync certification.
Does the Samsung S90H support Dolby Vision?
No. It uses OLED HDR+ and HDR10. The LG C5 supports Dolby Vision, HDR10 and HLG, which matters if you watch Dolby Vision content on Netflix or Disney+.
Which lasts longer?
Neither maker publishes a lifespan figure. The LG backs its platform with up to five years of webOS updates, which keeps apps current longer. Owner reports are mixed on both: LG owners cite software bugs, and one Samsung owner reported a hardware failure after a few months.
Is the LG C5 worth stepping up to over the Samsung?
Only if gaming and Dolby Vision matter more than glare handling. If your room is bright, the S90H's screen is the more useful advantage. If you play on PC or a console in a dark room, the C5's 144Hz and sync support are the reason to pick it.
Which has better sound without a sound bar?
Close. The LG C5 uses Dolby Atmos and owners say it does not need a sound bar. The Samsung S90H has a 2.1-channel 40W system with Dolby Atmos and an AI Sound Controller that separates voice, music and effects.
