Can anyone help? I am watching a Slingbox 350 playing BT Vision through an Ipad then Chromecast onto a TV. On the IPad the aspect ration is correct, but on the Chromecast its always 4:3, and I need it on 16:9. I have tried changing the aspect ratio on the Sling player, the TV and the BT vision setting, and nothing works. I have read on the posts on here about other TV boxes and tried what I can, but nothing works so far. Please help.
