Hi folks,

So i'm getting a power point installed right behind my tv which is mounted on the wall. I also have a sound bar under the tv also attached to the wall. No powerpoints will be visible. I also have a TV aerial socket right behind the TV for freeview HD also.

I always have my PC connected to my TV as i rather use a media PC over a smart TV. The only cable i need to try and hide now is the HDMI cable running from PC to the TV. The PC is sitting in a cabinet about 2 meters away from the TV.

Can anyone recommend a wireless HDMI transmitter for this? If my video card transmits audio through HDMI also, will this also be transmitted?

Failing this approach, i will have to run internal cabling in the wall but this will be a mission and probably quite costly.

Thanks in advance.

Think about it, the data rate running through an HDMI cable is 1.5 Gbps or so.

I guess the obvious question is...why didn't you put one in when you did the rest.
Anyway, 2 metres should only equate to one dwang  , shouldn't be that much of a mission.
Much better than wireless.

For the price you will pay for a full HD wireless solution, you could knock holes in the wall, plaster and paint and have a much better result for the future.

Have electrician run two x cat6, use one for Ethernet and the other for HDBase-T (the HDMI).

I'd go for the wired/electrical route mentioned above ...

But I must admit to also reordering and airtame.com wireless hdmi plug.

HDBaseT is the best way to go IMHO. I use an HDBaseT for 4K (HDMI 1.4b) over about 40M and it works 100% fine). The cheapest place (where I got my stuff) was from Monoprice.com

http://www.monoprice.com/Product?c_id=109&cp_id=10914&cs_id=1091401&p_id=10225&seq=1&format=2

The Power Adapters are 240/110V Input (5V output) but with straight pins but you can use a pair of pliers to bend the power pins (or buy some proper power adapters locally in NZ)

The ones I got didn't have the 100M ethernet as well (the ones on Monoprice are a little newer now) so if you only have 1 Cat5e/6 cable you can run 100M ethernet over it as well. (and it comes with IR as well)

Although I agree with the comments regarding running a physical cable if you can, I had a similar problem last year, where a cable was not possible. I bought a Belkin Screencast AV4 from PB Tech in Auckland ($101 at the time) and it works perfectly relaying HDMI wirelessly from our Sky box upstairs to a small telly in the kitchen below. Fair to say though that the distance between the transmitter and the receiver is only about three metres but is through floor/ceiling. MMV over longer distances.

It runs through an HDMI splitter so that we can watch Sky on the big TV upstairs and also in the kitchen at the same time. We can even change the Sky channel from the kitchen using a second Sky remote. 

All this was discussed here on gz at the time and some gz'ers were rather negative on the Screencast but all I can say is that ours works great. From PriceSpy it looks like you might be able to now get these for about $80. They were about $400 when first launched.

Sometimes I just sit and think. Other times I just sit.

Thanks everyone, good insights.

Why would you run an ethernet cable? Wouldnt i just run a 5 meter HDMI cable if going through the wall?

Many TVs have Ethernet ports and DLNA clients, certainly any TV of the future will take advantage of GbE. Not running Ethernet to a TV location is a mistake.

The secret with the Screencasts is to get the version with the latest firmware...
To my knowledge, the firmware isn't user upgradable, so ensure you can get the latest / greatest.
I have an older version that initially worked perfectly from downstairs to upstairs - 6 meters as the crow flies (through a wall and ceiling) but it does cut out from time to time.
I also use an HDMI splitter with MySky.
