Perspective Ratio and What You See On Your TV Screen

The reason that you wind up observing dark bars on a few TVs and motion picture content is that numerous movies were, and are, made in more extensive perspective proportions than 16x9.

For instance unique HDTV writing computer programs is made in the 16x9 (1.78) perspective proportion, which fits the measurements of the present LCD (LED/LCD), Plasma, and OLED HDTVs and 4K Ultra HD TVs. Notwithstanding, some dramatically delivered films are made in either the 1.85 or 2.35 perspective proportion, which is even more extensive than the 16x9 (1.78) viewpoint proportions of HD/4K Ultra HDTVs. Consequently, when seeing these movies on a HDTV or 4K Ultra HD TV (if displayed in their unique dramatic perspective proportion) - you will see dark bars on your 16x9 TV screen.

Viewpoint Ratios can differ from film to motion picture or program to program. In the event that you are viewing a DVD or Blu-beam Disk - the angle proportion recorded on the bundle naming will decide what it would seem that on your TV.

For instance, if the film is recorded as 1.78:1 - then it will fill the whole screen accurately.

In the event that the viewpoint proportion is recorded as 1.85:1, at that point you will see little dark bars on the best and base of the screen.
