The High Definition Multimedia Interface (usually just called HDMI) is an interface through which a transmission of video and audio signals over a single cable is possible. It was developed in 2003 and is now used not only to many computer systems, but is particularly prevalent in the consumer electronics industry, as it was originally developed for this purpose . We offer you our new and refurbished laptops, computers and components with HDMI interface, a selection of matching HDMI cables of different lengths.

What options does the HDMI standard

Since the publication were released several versions of the standard. The current version is 2.0 Since 2013 on the market and provides resolutions up to 3840 × 2160 pixels (also called Ultra HD), including support for 3D content and of course the corresponding audio channels. But users who use a version from 1.3 to come already enjoying a resolution that goes beyond full HD. This is especially important for monitors with a screen size from 27 inches or the control of TVs with the notebook. Unfortunately, it can happen that the resolution by the firmware or software is limited to 1920 x 1080 pixels and can only be increased by alternative driver.

What qualities pay attention to when buying?

with regard to the cable you are generally best to consult with the so-called HDMI high Speed ??variants because these lengths to support up to 7.5 m and an image quality of Full HD 3D is easily possible. For devices with HDMI connection labeling must be done since 2012 by the manufacturer, which functions are possible. A sole indication of a version number is here no longer permitted and even forbidden, as this does not allow conclusions on the given functions and thus is misleading. If the cable length exceeds 5m limit, you should increasingly pay attention to the processing of the cable, otherwise can quickly occur disturbances in image and sound quality. According to developers lengths up to 15m are generally provided . But also are 20m available to part . Use special cables, the optical waveguides, even allow a distance of 100m.

Regarding the compatibility is that this is basically to DVI- D and DVI -I. It is possible to walk with a suitable adapter, the DVI interface for a graphics card into an HDMI port. Through various transmission methods and the operation of devices from different manufacturers but it can come especially in the field of consumer electronics to errors. For computers, this is usually not a problem Some of our refurbished graphics card with HDMI port also have an integrated sound chip to provide additional output audio signals via HDMI. This is easily perceived by the operating system displays a second sound card, which can be managed the same way.
