Icon ask Sir ApfelotQuestion: How many pixels do the 4K televisions have?

Answer: The term 4k is particularly common in consumer electronics for televisions and monitors. The term 4k2k, which describes a digital HD video signal, is more specific. The "rough" resolution of 4000 x 2000 - as 4k x 2k - should show how many pixels the picture has. In practice, however, a resolution of 4096 × 2304 pixels or 3840 × 2160 pixels is used depending on the aspect ratio of the image. Compared to HD TV, 4K televisions have four times the resolution. For this reason, the 4k2k TV is also traded as the successor to the full HD TV devices.

However, the Consumer Electronics Association (CEA) decided in October 2012 that the official name for these playback devices should be given the addition Ultra-HD instead of 4k. So one no longer speaks of 4K TV but of [Ultra-HD-TV-> ultra-hd-tv]. In order to be allowed to use this additional term, the device must be able to display at least 8 million pixels. In practice, the most common resolution is 3840 × 2160 pixels.
