The Jungle Of HD Labels

The multiplicity of HD logos and labels qualifying screens and projectors could easily lead you to confusion. To make sense out of it, here are a few definitions:

- HD Compatible: this generic label just means that the screen can display a 720p or 1080i source, but with a final resolution lower than these two standards. Hence, you should avoid it.

- HD Ready: this standard launched in June 2005 was defined by the EICTA (European Information & Communications Technology Industry Association) and in France by the HD Forum. It provides:

* The availability of both analogical and digital connectors (e.g., HDMI)
* The ability to display both 720p and 1080i sources
* A screen format of 16/9
* Compliance to the HDCP standard (which protects works against piracy)

- Full HD: this is currently the highest standard in terms of resolution as it provides a native resolution of 1920*1080, which corresponds to the 1080i. Although theoretically higher in quality compared to HD Ready, usage of the Full HD label is not subject to a schedule of conditions. Hence, pay attention to aspects other than the resolution (e.g., availability of digital connectors, etc.).
