APPLE TV not streaming in 4k when bettery dummy is running

[melcarthus]

I'm using better dummy for two days now. And i'm really happy I found this app to help with the horrible scaling macos does.
However I noticed today that when running better-dummy apple-tv is stuck at streaming 1080p. When I closed better dummy it immediately started streaming 4k after I restarted apple TV.

I don't know If I got a setting wrong ore something.

Hi @melcarthus

Yes, this issue is related to #49

However lucky timing as I'll post a beta update in a day or two that should fix this issue by using an alternate method (that is if you are using a mirrored dummy to have flexible resolution options).

Well, apple TV app is for entertainment purposes so this is not a big deal. When I use my mac for work I want to use better dummy. So it's fine. But great that there is a possible workaround comming!

Hi @melcarthus - try the latest v1.2.5b beta with natively supported smooth resolution scaling - that should fix the Apple TV issue! :)

I've installed the update. How does this work now? What should I do? Apple TV is still streaming 1080p.

Hi there,

to enable the feature,

1. simply navigate to the Displays section in Preferences,
2. enable the Edit and manage the system configuration of this display feature first under a suitable display,
3. and then enable the Allow smooth resolution scale option just below it as it appears.
4. If you did this for all the relevant displays, click on the Apply System Display Configuration button at the bottom of the screen,
5. enter your admin password and then reboot.

The feature is compatible with Monterey 12.4+ and Apple Silicon macs.

Hope this helps!

I just added a quick tutorial here as well: https://github.com/waydabber/BetterDummy/blob/landing/README.md#how-to-unlock-scaling-and-hidpi-for-my-display

I've setup better dummy from scratch after the update.
I can't get my main screen/dummy above 60 hz and streaming above 1080p.

Hi there, if smooth scaling is set up for the display, dummy mirroring does not need to be enabled - if it is enabled, then the dummy takes precedence, which would mean 60Hz max and no HDCP. Can you send me a screenshot of what you see in the app menu? Thank you!

Hi, I have removed the app from the system en did a fresh reinstall. I now only have the below options enabled. Should I still create a dummy but not mirror it? or is running betterdisplay with the below options checked enough? I also get the message from the settingsapp that scaled resolutions might impact performance. I though that using the app's scaling method would not do this. I what else do I need to set? Is there a A- to Z step guide on how to set this up?

[melcarthus]

hey! I think everything is working as intended now.

1. I installed the beta.
2. enable the Edit and manage the system configuration of this display feature first under a suitable display,
3. and then enabled the Allow smooth resolution scale option just below it as it appears.
4. Reboot
5. Added a dummy but connected it (no mirroring).

After this it looks like everything is set. Apple TV is streaming in 4k. My monitor scaling setting does not show the warning message about impacted performance due to scaling.

Sorry it is working, but I spoke to soon about the impacted performance message. That is still there.

[waydabber]

The performance impact message appears with every scaled resolution since the original retina MBP. While the statement is technically true (of course more graphics will have more performance impact), if you don't feel the graphics is choppy, you can disregard it. :)
