Just sharing this here incase it's useful for someone else.

I've had a 4th gen Apple TV hooked up to an old 20" Cinema Display for a year (I like the design of the monitor). It's been great apart from I haven't been able to play Netflix and Prime due to hdcp. After buying 5/6 hdcp strippers and returning them I finally found a way to get it working. I bought a £20 hdmi to dvi+audio box on amazon. All working perfectly!

I did have to manually set the resolution to 1680x1050 and colour to rgb.

Here's the link:

Interesting! I tried several years ago to get my old 24” Cinema Display to work with an Apple TV 4 but at the time, the Apple TV didn’t carry the correct resolution for the display. Wonder if it’d work now...I’d love to use it as a spare tv for my office or something.

Also, the link doesn’t appear to be working...

No idea why macOS doesn’t have a simple Apple TV app or emulator to run all those apps.

I've only tried with my 20" sorry so couldn't say. It tells you all the resolutions it supports in the settings app in the Apple TV. I'll try my 23" at some point.

Hello there
I stumbled across of this as this almost identical to the problem I’ve described here:

https://discussions.apple.com/thread/8540671

So to be clear - before tvOS12 - was able to successfully connect several AppleTV 4th Gens to BOTH 20” and 23” Apple Cinema Display (i.e. the aluminium ones) without any issues + I was able to play any contents - iPlayer, Neflix, Amazon with issues. I simply used DVI-HDMI Adapters from amazon to connect the appleTVs to the monitors with out issue in tVOS 11.x and previous.

However since tvOS 12.x the apple TVs are unable to connect to the 23” screens (has very similar symptoms to above where their apple logo appears but then it goes black; whilst you are able to get screensaver working you cannot get to the menu, even with changing the video modes with remote). It should be noted the the appleTV with 20” monitor is just fine. Weird.

I’ve tried different adapters (from Amazon) without any luck so can you (yellow bunny) kindly confirm precisely which adaptor you bought as the link no longer works?

All the best and thanks

Hey! Ive been looking all over the web for answers, and ended up here!

I have an old Apple Cinema Display, 20-inch, aluminum LCD monitor that I love and that I want to connect to my Apple TV. I assume this is the same monitor as yellobunny is referring to(?). I have a simple HDMI to DVI adapter and it works, but the resolution doesn’t get quite right. Of all listed resolutions, only two kind of works:

- 1680x1050 (60Hz): fills the screen, but as a 16:9 image stretched to fill the 16:10 display, vertically stretched/wrong aspect ratio
- 1080p (60Hz): aspect ratio is correct, but the screen crops a bit of the bottom and a lot of the right side

Yellowbunny; can you confirm that you got the same setup working (monitor and Apple TV) with correct resolution and aspect ratio with this adaptor? https://www.amazon.co.uk/dp/B072KK8R2S

Thanks a lot! :)
