How Much Better Is The Quality?
Currently, television pictures are made up of 525 lines that are scanned horizontally. HDTV pictures are created by scanning 1,080 lines. Adding twice the amount of lines multiplies the amount of pixels (the small dots that create the picture). Current sets have about 300,000 pixels, while an HDTV screen is composed of more than 2 million pixels. Having more pixels on your screen will dramatically improve the sharpness of your pictures, allowing you to see picture details like never before. HDTV sets also have wider, movie-theater like screens that more closely resemble human peripheral vision, making it more natural to watch.
G3 fax machines support two image resolutions: 200 x 100 dpi (standard mode), and 200 x 200 (fine mode). G4 fax machines support a resolution of 400 x 400 dpi, which is as good as most laser printers. In addition, G4 features 64 levels of gray, so text is easier to read and illustration and photo fidelity is preserved.
