Not HD

Sorry but this APP is not HD, the image quality on a 27 inch Imac is rubbish.
Full of pixels, very disappointing indeed, I am actually very surprised that no one really mention this on what I honestly believe is a very expencive APP for the image quality it produces and it as no sound what so ever.
The only cool ficture indeed is the lock of the screen.
