Picture and sound quality
Screen resolution. This parameter is really important, since the clarity of the image on the screen largely depends on it. Resolution is especially important for large-diagonal TVs. Today, the most common TVs with resolution formats are HD ready (1280x720 pix), Full HD (1920x1080 pix) and Ultra HD (3840x2160 pix).
Ideal image quality is achieved only when the resolution of the video signal completely matches the resolution of the TV screen. In any other option, it will be necessary to use signal interpolation using software methods, adjusting it to the physical resolution of the screen matrix. Therefore, when choosing a TV resolution, you should take into account the type of signal that will be supplied to its input: terrestrial or cable television, DVD or Blu-Ray format, etc.
