I have an issue running hdmi out from my z1 to my TV. I'm using the official mhl adaptor and the TV is Sony hx853. However, the black levels are terrible. It's like the localised dimming is just not working at all. It's horrible to see everything so washed out I don't get it on any other hdmi output devices. The cables are absolutely fine and obviously, there are no tweakable settings as the hdmi signal should be bit perfect going into the receiver. Could it be a faulty mhl adaptor? These official ones are really expensive :/ be grateful for any help or insight into the matter! Thanks.
