The Samsung S90D is a 55-inch 4K OLED TV with a 120Hz panel. Each pixel lights itself, so blacks are absolute and contrast is effectively infinite, which no LED-backlit set matches. It suits movie watchers, gamers and anyone who wants deep blacks in a bright or dark room. Against rivals like the LG C-series it uses Samsung's QD-OLED panel for stronger color volume, but it has no Dolby Vision and its stand and sound are modest.

Owners and reviewers rate the S90D highly for its contrast, color and gaming features. Common complaints are the lack of Dolby Vision and average built-in sound.
The Samsung S90D is a 55-inch 4K HDR OLED TV in a Titan Black finish. Each pixel produces its own light and can switch off completely, which gives true black levels and infinite contrast. The panel has 4K UHD resolution (3840x2160) and a 120Hz refresh rate for smooth motion.
It connects over WiFi and supports Bixby voice control. RS-232c serial control lets it work with control processors such as Crestron, AMX, Extron and Control4. Through them it can be powered on and off, switched between inputs and have its settings adjusted as part of an automated room control sequence.
OLED panels can develop burn-in when static content is shown continuously for long periods. Content with varied screen elements suits the display best.
