We have been testing several wireless HDMI products, one looking exactly like the one you mentioned in Giraffe's website but with another brand. So far, the prices have been prohibitively expensive (around RM1.5k, without splitter and cables) and the worst part is the picture quality that is very poor. There is significant compression that can be seen, the refresh rate also drops drastically and some of them are not stable.

This is because Wireless HDMI is not an easy thing to do, especially at further distances between the transmitter/receiver. We would certainly like to offer this to our customers right now but we feel that many would be disappointed by the picture quality. Unless the customer is willing to accept these deficiencies of wireless HDMI, we would rather not have an unhappy customer. For now, Cat5e HDMI extensions are the most cost effective solution and will continue to be the best choice for people who are willing to do some rerouting of the cables.

Added on December 30, 2010, 12:07 pmThe cables that we provide are white in colour, and have a diameter of around 4mm each. Hacking of the walls is entirely up to you, as some customers do not mind using cable housings, or clipping it to the corners of the wall or ceiling. Having a plaster ceiling also helps, as this allows you to run the cables across rooms without them being seen. Each customer's house is different, and thus it is difficult for us to offer any further advice without seeing the premises. The best person for the job would typically be your existing contractor/wireman/linesman/electrician. They would be familiar with your house and where the voids are, and usually have experience doing this kind of work.




But if already got plaster ceiling how? Need to hack?
