Solid functional MHL-HDMI adpater tested on Xperia Z2
on 15 October 2014
The Sony packaging is a little unusual (like a squashed rectangular box so the top resembles a rhombus shape).
You need like other MHL to HDMI devices it needs a power supply connected to function in the form of a micro USB plug. I used this on Xperia Z2 device without problems and connect the other end of the cable to the phone's micro USB port. Note whilst all connected it charges the phone which is an added bonus.
Note this won't work on the 11-pin MHL devices like Samsung, as it the 5-pin MHL standard for most other phones as I understand it. The HDMI TV/Monitor won't detect the phone output unless it is powered by an external micro USB power supply. Once all connected you will get the phone display on the screen. Additionally the Xperia Z2 will detect this and offer a slightly different page layout that tries to be more TV orientated.
Playing games on the big screen like Real Racing 3 is more pleasurable, but the frame rate of the HDMI doesn't match the frame rate normally delivered on the native phone display accelerated by the Qualcomm graphics on the Z2. What you will notice is a drop in frame rate of the game as you are normally used to. I don't have any numbers to quote, but visually it is noticeable. This I think is not a criticism of the Sony MHL adapter, but a by product of switching to HDMI.
Photo slideshow and Video player output on the big screen works well and good for sharing photos with everyone at home easily. The only issue I have which might be an issue with the amount of current (power) the power adapter can deliver or the resultant power being offered to the phone through the MHL device, on the Z2 I get messages to say the power demanded by the application (plus MHL adapter) can't sustain charging. Annoying messages which I as yet don't know how to disable.
Otherwise works well as it says on the tin, er box. : )
