In this Samsung UN19D4000ND review, we’ll discuss the Full array backlighting, the average refresh rate, the 19-inch LED-LCD screen, and the price. Hopefully, you’ll be able to make an informed decision when purchasing a monitor.
Full array backlighting
Full array backlighting is a great feature for HDR content. Unlike edge-LED backlighting, which uses LEDs only on certain areas, full-array backlighting uses LEDs to illuminate the entire screen. This allows for precise control of brightness and power, keeping dark areas dark and light areas bright.
Full array backlighting gives the best contrast compared to edge-lit models. Edge-lit TVs use LEDs along the edge, facing the center of the screen. While this method is effective for dimming large sections of the picture, it is not effective for pin-point dimming.
Full-array LED displays have the backlighting bulbs embedded behind the screen, while edge-lit LEDs have the backlighting bulbs on the sides. Both methods produce bright and clear images, but the full-array backlighting produces higher-quality images.
Average refresh rate of 60 Hz
You can find out the average refresh rate of a TV from the technical specifications of the model. However, you should be aware that it doesn’t always mean that the higher the number, the better. There are times when the higher number will make the picture look a bit softer, and the opposite is true if it creates a lot of motion blur.
The refresh rate of a TV is usually measured in frames per second. Usually, 60 Hz displays are capable of displaying up to two frames per second. This means that you can see images much more clearly on a 60 Hz display. Some TVs even have a 120 Hz refresh rate, which is double the rate of a 60 Hz source.
The average refresh rate on a 4K TV is 60 Hz, while those with 120 Hz panels usually feature an average refresh rate of 240 Hz. However, the number quoted above doesn’t represent the real refresh rate of the TV, but rather the rate that is generated by image processing. For most consumers, this means that the difference between 60 Hz and 120 Hz is too small to be noticeable.
Refresh rate is an important aspect of TVs. This determines how often a new image is displayed on the screen. Refresh rates are measured in Hertz (Hz). If the rate is 60 Hz, the image will appear to be smooth 60 times per second.
The Samsung Model UN19D4000NDXZA comes with the following components: main board, motherboard, power supply board, remote control, stand base, guide and lcd/led display panel. If you are looking for a cheap television that can meet your needs, this might be the right choice.
