How do you insulate an HDMI cable?
HDMI cables typically include two layers of shielding — foil and braid — designed to block high- and low-frequency interference. You can provide additional shielding for an HDMI cable by wrapping it with aluminium tape.
Does length of HDMI cable affect picture quality?
In a nutshell, yes, the length of the cable affects the audio and the video quality. This is mainly because of the fluctuating signals as the sound and video travel through the HDMI cable. In general, there is no specific length that tells you that the HDMI cable is too long or too short.
Do gold plated HDMI cables make a difference?

Are 8K HDMI cables worth it?
Gamers, especially gamers looking for 4K120 or 8K performance from their newest consoles or gaming PCs, should keep an eye out for Ultra High Speed cables. The higher bandwidth means smoother graphics, which TV shows and movies generally don’t rely upon, but high-end gaming can take advantage of.
Do expensive HDMI cables make a difference?
An expensive HDMI doesn’t produce richer colors or crisper sound than cheaper versions. However, an HDMI cable made with better materials can be more durable, and support higher bandwidth at longer distances, but it won’t offer any difference with the picture quality.
Can you run HDMI next to electrical?
never run the electrical parallel with any data or speaker cable including hdmi. If they have to cross, this shouldn’t be a problem but do whatever you can to make sure they don’t at least touch.
