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.
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.
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.
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.
