HDMI: Getting the digital picture. What is it? HDMI = High definition multimedia interface. An HDMI cable transforms digital audio and video. It's the standard for home theater components, HDTVs, and HD computer monitors.
Why do you need it? HDMI cable delivers the clearest picture and sounds. Connect HD video sources such as blue-ray players, game consoles, computers, satellite and cable TV bodies to HDTVS, HD monitors, and receivers such as home theaters.
The HDMI Advantage: DVI and analog signals require separate cables for audio and video. HDMI transmits audio and video in one cable. Digital signals done degrade like analog signals. You either have picture and sound or you dont. HDMI transmits faster than DVI and supports higher resolutions.
How to choose an HDMI cable:
Standard vs. high-speed HMDI.
standard HDMI cables support 1080I or 720P signals. High-speed HDMI cables support 1080P, 3D, and 4K signals. Choose a high-speed cable to have support for current technologies.
With or without Ethernet:
HDMI with Ethernet cables.
-Carry audio, video, and network data to devices with HDMI Ethernet channel functionality. No separate ether net cables.
-Carry audio and video to devices that dont have home Ethernet channel functionality.
Good quality: purchase cables fro a reputable manufacturer to ensure quality. Some offer a lifetime warranty! Need to send HDMI more than 30 ft? Use over CAT5/6 extenders and splitters to send HDMI signals over CAT5/6 cable when your HDTV is far fro the HD video source. Extend a 1080P signal up to 150 ft.
HD video source > high speed HDMI cable > transmitter > CAT5/6 cable > Receiver repeater or splitter > high speed HDMI cable > HDTV.
