Imagine you were given a box of 24 crayons and you were told to replicate a high definition photograph. Good luck with that. It would be rather difficult and the end result might be less than impressive. The last generation of TVs that do not have HDR, or High Dynamic Range, capabilities are playing with a small box of crayons. Ok, that may be a bit extreme, but non-HDR TVs have limitations and the High Dynamic Range technologies are able to get past them. When your old TV gets a signal from a Blu-ray player it contains a limited amount of data with a Standard Dynamic Range (SDR). HDR allows for additional data to be sent to your TV. It now includes more information on brightness and includes a wider range of colors. The end result is an overall better picture. Much like a laundry detergent commercial, your darks will be even darker and your lights even lighter.
