Overview
The Samsung QN55S90FKIT1 is a 55 inch 4K OLED television with a 144Hz refresh rate, aimed at buyers who want both picture quality and higher frame rates for fast motion or gaming.
The S90 series sits in Samsung's OLED lineup, and the 144Hz refresh rate stands out at this size, since most TVs in the class top out at 120Hz. That extra headroom mainly benefits PC gaming or consoles that support higher frame rates over a compatible HDMI connection.

Who it's for
Gamers and movie viewers who want a 55 inch OLED with an above average refresh rate. Less relevant for buyers who mainly watch standard broadcast or streaming content, where the 144Hz ceiling goes unused.
Strengths and trade-offs
Drawn from this product's published specifications.
- 55 inch 4K OLED panel
- 144Hz refresh rate, above the typical 120Hz ceiling
- Wi-Fi, Bluetooth, and Ethernet connectivity
- Tizen smart platform
- 144Hz benefit depends on a source device that supports it
- 48 lb weight and listed dimensions suggest a stand-mounted setup needs floor space
Performance notes
OLED display technology lights each pixel individually, which is what produces the deep black levels the format is known for. The 144Hz panel refresh works with compatible sources to reduce motion blur and input lag in fast moving content, though the benefit only shows up when the connected device outputs at that rate.
