WebAnalog dimming changes LED light output by simply adjusting the DC current in the string, while PWM dimming achieves the same effect by varying the duty cycle of a constant current in the string to effectively change the average current in the string. WebMay 21, 2024 · The TCL has a higher native contrast ratio, and it has a full-array local dimming feature that improves the contrast significantly. It also gets a lot brighter, enough to deliver a true cinematic HDR experience. The TCL has a 120Hz refresh rate, whereas the Samsung's is 60Hz, but it lacks HDMI 2.1 ports, so it can only display a 4k @ 60Hz signal.
