Our Verdict
LG G4 OLED
Samsung S90F OLED
The LG G4 OLED and Samsung S90F OLED trade blows. The LG is a bit brighter in HDR and SDR, but the Samsung is more colorful. The LG is more accurate in HDR out of the box, but the Samsung has more accurate HDR brightness tracking. The LG generally has better image processing, but the Samsung has less banding in its HDR gradients. The biggest difference between these two is that the LG supports Dolby Vision and passes through DTS audio formats, while the Samsung sticks with HDR10+ instead, and doesn't pass through DTS audio. This gives the LG the edge in home theater scenarios, but the Samsung has a bit more pop for color lovers.
