With the upgrading of HD devices, many HD devices such as LCD TV, Blu-ray DVDs and HD projectors are applied HDMI to realize the synchronous transmission of images and videos. Most users pay more attention on how to choose an HDMI. However, it’s also very important to choose an HDMI cable. You can detect the HDMI cable’s quality by these following aspects. Construction and materials — Characteristics like conductor thickness, quality of shielding and insulation, and innovative internal design features intended to enhance the performance and reliability of the cable. Speed rating — All HDMI cables Best Buy sells are rated to handle a continuous throughput of at least 10.2Gbps, which is certified to be compatible with HD signals up to 1080p resolution (including full HD 3D). Higher speed ratings indicate increased bandwidth to support additional video, audio and intercommunication features of emerging and future technologies. Bit depth rating — Better HDMI cables offer higher bandwidth and are therefore certified to pass more nuanced color information than lesser cables. Basic HDMI cables typically handle a stream of 8-bit color information, whereas more sophisticated, high-bandwidth models are optimized for 10-bit, 12-bit or even 14-bit color depth. Connector enhancements — Higher-end HDMI cables often sport connectors fabricated of zinc oxide for improved EM and RFI shielding and/or electroplated in gold for reliable electrical coupling and corrosion resistance.
