But it does detect AirPlay in Quicktime and other apps that use it's functionality natively. But Apple capped the 27" probably because that way you "need" a better device.Īirplay also doesn't show in the menu-bar, and I'm on an iMac 27" that has a resolution of 2560x1440.
How to airplay from mac os sierra to apple tv 1080p#
You change your monitor's resolution in the display settings right? Try that and match the resolution to your streaming devices and monitor's MAX resolution.īut I tried it and it doesn't yield the result you want to stream your desktop.įunny enough it does work on a 21,5" iMac 2011 or 2010 they both have a native-resolution of 1080p and will stream without problems. Done.īut it will not mirror my desktop to my TV, since it uses a higher resolution that the AppleTV or the TV itself will support.
So my iMac 2010 can stream to a device, but only up to 1080p, which my TV will support since the Apple TV reaches it's MAX, and the TV too. These can only process certain bandwiths and speeds, like the wifi modules only pick up 2,5ghz, and use 300MB (I believe), not the 1200MB on 5ghz. If you see the obvious "out of bounds resolution" in either of these devices, this is why it can not make that bridge to steam the resolution to begin with. I have HDMI 1.0, and an Apple TV (2) that supports up to 1080p.Ĭheck what kind of resolution your monitor support, check the version of your HDMI cable, and check the resolution of your Mac's monitor. The point of HDMI versions is often overlooked, but describes the MAX-output your monitor can support. 1.0 can go up to 1080p, 1.1 can stream up to much higher, and I believe you need a HDMI 1.2 capable device to display 4k and such.
The second factor that goes into play here is HDMI 1.0, 1.1 & 1.2 which are just versions. I have some insights on this subject I want to share, because many don't realize that older Macbooks and iMacs have alder bluetooth and wifi modules.
