An LCD monitor is simple to install: once connected to the computer, pressing the on / off button makes it ready to use system. However, there are different types of connectors, all entrenched behind acronyms barbaric. Here's a mini-guide to be noticeable in the cables.
All screens are equipped with a VGA (Video Graphics Array). This allows the transmission of an analog signal from the graphics card from the computer to the LCD monitor. This connector, which is getting old, gradually gave way to the digital inputs. These constitute a real "plus" because they preclude any image degradation associated with analog / digital conversions (using an analog VGA output forces the computer to convert the image in this mode, image that will then be converted to digital to be displayed on the screen - the process can only harm the signal quality). Thus, most screens also offer a DVI (Digital Visual Interface) or HDMI (High Definition Multimedia Interface). This type of connector to transmit high definition content, such as those emitted by a Blu-ray DVD player or a game console like Sony Playstation. Beware, however: for viewing HD videos (this does not apply to programs of the TNT HD), the screen also has to be certified HDCP (High-Bandwidth Digital Content Protection). One point that moviegoers should check.
The locking high definition
HDCP (High-Bandwidth Digital Content Protection, for "protection of digital high-definition content") is a protocol developed by Intel (particular) to protect content in high definition against copying. To exploit this specification owner, the manufacturer pays a license. Specifically, to fully enjoy the high definition pictures, all devices used in the processing chain must be compatible. This is the case for projectors, Blu-ray players, TVs. And, increasingly, for computer monitors. We must check this if you plan to connect your display with a Blu-ray player or Sony Playstation games console kind. Indeed, if one link in the chain is not HDCP compliant, the HD signal will be degraded or even ... unusable. In this case, curtain on the screen: it desperately remain black!
