I contacted the MS TS and they sent me the new driver (117MB file). Installed on my SP3 i7/256 and the version of the driver is 10.18.14.4080. Reboot and tried Screen Mirroring on my 2 Sony TV sets (KDL-50W800B and XBR-49X850B). In both cases I was able eventually to connect but connection was usually dropped after 2/3 minutes. I tried the MDA on both TV sets and all worked just fine.
Interesting thing is both TV sets work fine when I try Screen Mirroring from my cell phone (Samsung Galaxy Note II). KDL-50W800B occasionally drops connection but XBR-49X850B works solid.
In my opinion MS/Intel need to do more tweaking before the driver is 100% reliable and ready for general public.
What new driver are you referring to?
New driver for what?
I struggled for a long time trying to get my Surface Pro 1 to connect to my 2014 Sony XBR55850B and the Start Screen will go to the TV and then the TV sits there waiting for more signal but nothing else happens.
I refuse to buy an adapter to make something work that should work out of the box.
I'm wondering if the new driver you refer to would work in the Original Surface Pro and if it would help.

Anyone who has the adapter working, can you tell me which driver version you have?
