Interesting to note that if you have an iPhone 6 Plus ... both Airplay mirroring, and direct connection with the Apple Lightening to HDMI adapter fills the entire 16:9 screen because of the full HD 1920 x 1080 pixel screen of the 6 Plus.
So... until GS provides native airplay - if you have a iPhone 6 Plus around, that will do the trick. The clarity even of the text in documents is quite good! Beautiful image.
The one request I would make having just tested this, Csaba, is for the top menubar to auto-hide to show even more of the model and less distraction when doing a presentation.

PS Could someone test with a standard iPhone 6 which is 1334 x 750 pixels? That is still 16:9, so it would be interesting to see if the cable and/or AppleTV will display it in full screen on the TV, or if it will have a black border.
iPads and older phones don't have 16:9 screens, so this workaround isn't an option there.
