Extension cables make it easy to connect if your television screen is far from your laptop. You can still plug in your HDMI and watch your favorite movies or shows from your comfy sofa. This adds to all the conveniences HDMI extension cables provide.    

Also, this isn’t limited to a laptop or television screen. You can use an extension cable for any device that supports HDMI.

In some cases, you may not need an HDMI extension cable. For example, if the cable is sort, you can move a portable device quickly.

However, that may not be possible if the equipment is heavy or fixed. Hence, your only option is to turn to an extension cable.

An excellent thing about HDMI extension cable is that it does not affect audio or video quality. This can be a problem if you opt for a long HDMI cable. 

They cannot support high quality, and you will not get the level of performance you expect from HDMI cables.

This is why some experts suggest using an extension instead of opting for a longer cable. Also, longer HDMI cables can be hard to find.

According to reports, HDMI cables suffer signal degradation after about 50 feet. Hence, if your distance is longer, it may be good to opt for an extension instead of ordering a custom cable.

An extension cable may reduce signal strength after a point, but it does not impact sound and video quality.

Hence, for as long as the cable works, you will see no reduction in quality. Other than this, you may also use an extension cable to change connector types.

For example, if your current HDMI cable is micro HDMI. Then you can choose an extension cord that increases the length and offers a different cable type, so there is no problem when connecting.
