Sony KDL-40CX523 playback issues

Not sure if anyone else has expeienced this, When i first starting using Serviio (0.6.2) it detected my sony as a generic tv/dlna. Changed the setting to Sony 2009 and everything works perfectly including all resizing.
Just upgraded to v1.1 and tv detected as generic/dlna again. Changed it to Sony 2009 and now everything is displayed in letterbox or in a box on the screen.
Checked the forums and can't seem to find anyone with this issue. Can anyone help ?
