This UN19D4000ND review will give you the lowdown on this LED backlit monitor. You will find out about the Refresh rate, LED backlighting, and Test results. After reading this review, you will be able to make the most informed choice possible. Here are some other things to keep in mind:
The Samsung UN19D4000ND has a 19-inch LED-LCD screen. It has HD resolution, but it doesn’t quite live up to its competitors, like the Haier L19B1120. This TV has an average refresh rate of 60 Hz, which means that the screen updates its image 60 times per second. To help you decide which TV is best for your needs, SpecsPRO has listed down some key features of the UN19D4000ND, as well as its competitors.
LED backlighting has many advantages, including increased energy efficiency and a longer life span. This type of backlighting uses no mercury, or other toxic elements, in the manufacturing process. While the frequency of dimming pulses may vary from LCD to LCD, it is still more environmentally friendly than other backlighting options. The high frequency of PWM dramatically improves the dynamic range and perceived contrast ratio of LCD screens while reducing the amount of power consumption.
The full array backlighting feature of the UN19D4000ND is designed to break down the direct LED lighting into multiple zones, each illuminating a part of the screen and enabling each zone to independently dim depending on the content. This type of LED backlighting allows the television to deliver deeper shadows and brighter highlights, as well as more vivid colors. This is particularly useful for viewing HDR content, which can be brighter and more realistic.
The downside of LED-backlit displays is that they don’t produce true black colors and scenes. The light source is spread thinly throughout the center of the display, making it difficult for scenes to appear accurate. A full LED display, on the other hand, can produce true blacks as light is evenly distributed across the panel. Furthermore, full-LED panels can be turned off individually to create a dark image.
