Can my display or projector play back high-resolution content?

Your output device (plasma/LCD TV, display or projector) should specify that it is "HD ready", which indicates that it can play back Blu-ray discs, i.e. minimum native resolution of the display is at least 720 physical lines, and be capable of playing back 720p (1,280 x 720 dots in full-screen mode) and 1080i (1,920 x 1,080 with 50 Hz interlaced, i.e. in half-screen mode/ PAL) formats.

A "HD ready" device must also be compatible with the HDCP Digital Rights Management system. This means that, among other things, it has to at least have either a DVI interface with HDCP or an HDMI interface.

Contact the manufacturer directly if you aren't sure whether your display supports HDCP.
Anyone who wants to exploit the excellent image quality of Blu-ray discs to the fullest should opt for a "Full HD" device with a resolution of 1920 ×1080 lines in full-screen mode (1080p).

The display or projector should also be capable of not just playing back image repetition rates of 50 and 60 Hz (progressive and interlaced), but also 24 Hz.

If your display has neither an HDMI nor a DVI input, you can play back your Blu-ray discs analogue via a D-sub/VGA connection - although the image quality will obviously not be as good.

Can my normal DVD drive also play Blu-ray discs?

No, it can't. However, our Blu-ray disc drives are fully downwardly compatible, which means you can use them to play all standard DVD and CD formats

Will I need internet connection for Blu-ray?

To playback movies you will not need internet connection. However, you will need connection if you wish to interact with the purchased BD-ROM movies that have interaction features such as update to date news or shopping.
