Difference Between Samsung Series 7 and Series 8
Samsung Series 7 vs Series 8
On the high end of Samsung’s HDTV line-up are the Series 7 and Series 8 models. This models have the best features and the differences on these models are much narrower compared to the models on the lower end. The most significant differences between Series 8 and Series 7 models is in the contrast levels, or the degree of separation between the black and white colors that it can reproduce.
Series 7 models have a contrast ration of 3,000,000:1 which is already a lot better compared to other models that have contrast levels of way less than a million to one. Series 8 models have much better contrast levels as its contrast ratios are indicated at 7,000,000:1. So, when you set the two displays side by side, you would surely notice that the Series 8 model has a better image especially in dark scenes.
The extremely high contrast ratio presented by the Series 8 models is achieved by controlling the LEDs that light up the display. On other displays, some light still seeps through when showing the color black. This results in a grayish color that is not representative of the true picture. By dimming or turning off some of the huge number of LEDs behind the screen, Series 8 models are capable of displaying black colors that are much closer to the black you see with the screen turned off.
Both Series 7 and Series 8 models are equipped with Auto Motion Plus. Models with this technology are capable of changing the picture on screen much faster than traditional displays. Instead of repeating the frames, Auto Motion Plus creates an intermediate picture that is derived from the two frames where it would be inserted. This creates more fluid motion that is faster than our eyes can perceive. On Series 7 models the refresh rate is at 120 Hz while Series 8 models have a 240Hz refresh rate. The higher refresh rate on the Series 8 models mean that it interpolates twice the number of frames that Series 7 models do. Samsung claims that high speed video appears a lot better on the Series 8 models than on the Series 7 models though all this happens at a speed that is much faster for the human eye.
