How To extend hdmi extension cable?

HDMI cables have simplified our electronic lives, but things get tricky when those cables have to cover a long distance.
Let’s give the mini HDMI cable some credit. It helped clean up the tangled mess of wires behind our TVs, gave us a way to quickly link a stunning range of devices with a new generation of displays and provided a sturdy backbone for the HD revolution. But for everything this unassuming all-in-one cable can handle, sometimes it comes up short.
Like many video, audio and data cables, hdmi extension cable can suffer from signal degradation at longer lengths—50 feet is generally considered the maximum reliable length. And it’s rare to see an hdmi extension cable longer than 25 feet in a store. Even online, vga to hdmi cable more than 50 feet long can be hard to find. If your TV, set-top box and other AV equipment are all on the same piece of furniture, this isn’t much of a concern. With a collocated setup, you’ll probably never need more than 6 feet of cable at a time.
But HDTVs have introduced a whole new way of arranging home theater gear. Flat screens are increasingly thin and lightweight, and their picture-frame profiles make them perfect for hanging on walls. Similarly, HD home theater digital projectors are now affordable enough for nongazillionaires to set up a basement cinema. A clean installation of either of these setups generally requires a bit of in-wall wiring, sometimes even from one room—an AV closet, for instance—to another. And when you’re fishing wires up into ceilings, over doors and under floors, the necessary spool of cable gets long quickly.
