Hi

I just purchased apple tv(3rd generation) yesterday.

I have samsung 4k tv serial # UN55HU9000FXZA

I also have Imac (27-inch, Late 2013)

I set up what it supposed to be. (connect hdmi and apple ID log in)

when i click airplay in imac to tv, it's blackout but sounds are working.

I tried with my ipad (most recent model) , worked so great mirroring , I have no problem at all with ipad and tv.

but my imac looks so weird , doesn't mirroring anything just blackout on my TV.

have you got this report before?

can you find out why doesn't work on my imac and tv? '

is this my tv problem?

then how come my ipad works so well ??

let me know

please

AppleTV 2, iOS 8.2

You need to set up the AppleTV and the iMac to work together. Here is a link to the instructions:

I stated that I already followed the instruction about airplay mirroring at apple support.

Still doesn't work.

Then you need to check the inputs on your TV and ensure the input from the AppleTV to the TV are correct. It works, you have just missed something in the setup. What I mean is, if for example your HDMI connection between the AppleTV to the TV is HDMI 1 on the TV, then you have to switch the TV to HDMI 1 input on it's menu and then begin using Airplay. If you cannot figure that out then give AppleCare a call and they can walk you through it.

you are right,

I did right setup air tv to tv.

I can see apple tv menu (i.e itunes etc ) , it displays very well, even ipad mirroring works well.

i can play itunes through apple tv, that works well.

when i click the airplay top left corner ,

tv turns into blackout but sounds working.

also one of weired thing is

i can't click the mirroring option in the airplay menu, just check marked on extended display.

so i also tried amount of times dragging new windows or movie clip over the screen, not working anything just black out but still sounds work.(movie clip)
