Best for Movies & Streaming

LG C4

Winner
  • Dolby Vision support - The gold standard for streaming HDR content on Netflix, Disney+, and Apple TV+
  • Superior tone mapping - Better handling of dark scenes and shadow detail
  • Filmmaker Mode - Preserves director's intent with accurate colors
  • Lower peak brightness may reduce HDR impact in bright scenes

Samsung S90D

Runner-up
  • HDR10+ Adaptive - Good for Amazon Prime Video and Samsung TV+ content
  • More vibrant colors - QD-OLED produces punchier, more saturated images
  • Higher brightness - HDR highlights pop more dramatically
  • No Dolby Vision - Limited on major streaming platforms

Our Take: For movie enthusiasts, the LG C4 is the better choice due to Dolby Vision support, which is used by most major streaming services. The superior tone mapping also means better shadow detail in dark scenes. However, if you primarily watch HDR10+ content or prefer more vibrant colors, the Samsung S90D delivers impressive results.

Best for Gaming (PS5, Xbox, PC)

LG C4

Winner
  • 4x HDMI 2.1 ports - Connect PS5, Xbox Series X, and PC without switching
  • Native G-Sync support - Best compatibility with NVIDIA GPUs
  • Dolby Vision Gaming - Enhanced HDR for Xbox Series X
  • ~9ms input lag - Slightly faster response for competitive play

Samsung S90D

Also Excellent
  • Higher brightness - HDR games look more impactful
  • Samsung Gaming Hub - Cloud gaming built-in (Xbox, GeForce NOW)
  • FreeSync Premium Pro - Great for AMD GPU users
  • Only 2 HDMI 2.1 ports - May need to swap cables with multiple consoles

Our Take: The LG C4 wins for gaming due to 4 HDMI 2.1 ports and G-Sync compatibility. If you have a PS5, Xbox, and gaming PC, the LG lets you keep everything connected. The Samsung S90D is still excellent for gaming with slightly better HDR brightness, but the port limitation is a real drawback for multi-device setups.

Best for Bright Living Rooms

LG C4

Good
  • Excellent anti-reflective coating reduces glare
  • Auto Brightness Limiter (ABL) helps in bright content
  • ~350 nits SDR brightness can struggle against windows
  • ~800 nits HDR peak may wash out in direct sunlight

Samsung S90D

Winner
  • ~450 nits SDR brightness - Better daylight viewing
  • ~1,300 nits HDR peak - Punches through ambient light
  • QD-OLED color volume - Colors stay saturated at high brightness
  • Good anti-reflective screen coating

Our Take: The Samsung S90D is clearly better for bright rooms. Its QD-OLED panel delivers 60% more peak brightness than the LG C4, making it significantly easier to watch in living rooms with large windows. If your viewing space has lots of ambient light, the S90D is the obvious choice.

Best Value for the Money

LG C4 - $1,799

Premium
  • $200 more than Samsung S90D
  • Premium justified by 4 HDMI 2.1 ports + Dolby Vision
  • 5-year panel warranty available from LG
  • Proven track record with LG OLED reliability

Samsung S90D - $1,599

Best Value
  • $200 savings vs LG C4
  • Higher brightness despite lower price
  • Excellent picture quality for the money
  • Often goes on sale for $1,399-$1,499

Our Take: The Samsung S90D offers better value at $200 less while providing higher brightness. Unless you specifically need 4 HDMI 2.1 ports or Dolby Vision support, the S90D gives you more for less. Watch for sales where the S90D drops to $1,399 - at that price, it's an incredible deal.
