LG C5 OLED TV vs Samsung S90H OLED TV

The LG C5 is the safer pick for most shoppers. It has four full HDMI 2.1 ports, Dolby Vision, G-Sync and FreeSync Premium, and a large base of owner reviews that consistently praise picture quality. The Samsung S90H counters with a glare-free coating that holds up better in bright rooms and a slightly higher 165Hz gaming mode, but it lacks Dolby Vision and has far fewer owner reports. Build quality is close on both, so pick the Samsung only if reflections or a brighter room are your main concern.

  • Choose the LG C5 if you want the most complete gaming feature set, Dolby Vision, and a long track record of owner feedback.
  • Choose the Samsung S90H if your room gets a lot of daylight and you want a glare-free OLED with a brighter, punchier picture.

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.

Samsung S90H OLED TV

Questions and answers

Which is better for gaming, the LG C5 or the Samsung S90H?
The LG C5 is the stronger all-round gaming TV. It has four HDMI 2.1 ports plus G-Sync and FreeSync Premium, which covers PC and console setups. The Samsung S90H reaches a higher 165Hz, so it edges ahead only if you chase the highest frame rates.
Which handles a bright room better?
The Samsung S90H. Its Glare Free coating suppresses reflections far more effectively than the LG C5's anti-glare layer, and OLED HDR+ lifts brightness. The C5 is still bright for an OLED but shows more reflections near windows.
Does the Samsung S90H support Dolby Vision?
No. It supports HDR10, HDR10+ and HLG. The LG C5 supports Dolby Vision, which matters if you watch a lot of Dolby Vision content on Netflix, Disney+ or disc.
Which one lasts longer?
Neither has a clear reliability edge from the data. LG commits to up to five years of webOS updates, which helps the C5 stay current. The S90H has too few owner ratings to judge long-term durability.
Is the Samsung S90H worth stepping up to over the LG C5?
Only if reflections are your main problem. The S90H's glare-free screen and higher refresh rate are real gains, but you give up Dolby Vision and the broader owner track record of the C5.
Which has better sound without a soundbar?
The Samsung S90H has a 2.1-channel 40W system with object tracking sound. The LG C5 is well regarded by owners for built-in sound, but the S90H's dedicated 2.1 setup gives it the edge for built-in audio.
