Q6:What is 4K Video Resolution

4K is a new resolution standard designed for digital cinema and computer graphics. It has following advantages: higher image definition quality, more detailed picture, better fast-action and larger projection surface visibility.
4K format was named because it has 4000 pixels horizontal resolution approximately. Meanwhile, standard 1080p and 720p resolutions were named because of its vertical resolution. The new standard renders more than four times higher image definition than 1080p resolutions for example.

This format can't have the change in horizontal resolution, so changes in aspect are made through the vertical resolution. For example 4096×2304 is a frame size with aspect 16:9 and 4096×3072 — 4:3. The digital video resolutions examples:
