Doesn't work with some HDMI equipment
Unfortunately the PS3 running to a Panasonic TH-P50Z70 TV via this cable/box won't pick up.
Same as a a Virginmedia Cable TV HD Box (UK)
A WD TV live box does work although seems to have problems detecting the correct resolution.
For reference I have 2 HDMI ports on the TV and 3 items to connect into it but using this item in multiple different combinations doesn't work unfortunately.
The light for detection turns up but no joy and the HMDI on the TV is fine and doesn't have an issue with either device.
As an educated guess it looks like it struggles with the signal unfortunately, and that the power is drawn for the box from the device(s) which is being plugged into it rather than the TV.
It may work on other devices but for me it's 2 failed and 1 half working out of 3 so I will be returning and trying to locate a better model.
