Connect Mac Mini to TV with HDMI extender via AV receiver

[apapagapiou]

Equipment:

Mac Mini
2.3GHz Quad-Core Intel Core i7
4GB 1600MHz DDR3 SDRAM - 2x2GB
1TB Serial ATA Drive @ 5400 rpm

Samsung LED HDTV

Yamaha RX V673 AV Receiver

I am trying to connect the mac mini to the TV via the AV receiver. Note that AV receiver is already connected to the TV and works a treat. I watch cable TV through that.

As a test, I first connected the mac mini directly to the receiver using plain HDMI cable with no problems. I can see my mac mini on my LED TV.

As the receiver is not going to be near the computer, I then purchased a pair of HDMI extenders over two cat5e/6 (link here) cables to give me a bigger distance between the computer and the receiver. I connect them and get nothing.

I have re-done the RJ45 connections twice so far but no luck.
I have also used a different pair of HDMI extenders which I has been using for something else (which I know definitely work), but again nothing.
I have tried different cat5e/6 cable with moulded RJ45 connectors and again nothing.

So I am wondering... could it be that the HDMI extenders that use two ethernet cables are perhaps not suitable for connecting a computer to a TV, and I need HDMI extender over single ethernet cable (something called a balun).

I am not a techie and have been attempting all this following tips and advise from friends etc.

Any help would be appreciated.

Many thanks in advance

No idea regarding extenders - but another option is plug an Apple TV into the receiver, and use AirPlay Mirroring.

Are you using shielded cat 6 cable with shielded connectors? I know most HDMI extenders recommend or require these. Or as FreakinEurekan recommended using airplay, I would think that an Apple TV would be cheaper than most HDMI extenders. I have seen mac Minis work fine over professional HDMI extenders, however these extenders will run you more than the basic mini.

I suppose the connection between the Samsung LED HDTV and the Yamaha RX V673 AV Receiver is HDMI too.
Easy to check if the problem is the Mac Mini or the long HDMI extender : replace the current HDMI connection between TV and Receiver by the extended one. If it does not work, the Mac Mini is innocent.
