I'm cleaning the house and I want to get rid of all the stuff I don't need, so if I have "ui_resolutions=hd" and Roku scales automatically for the other resolutions, do I have to provide fhd and sd background images? What about splash images?

Not sure what do you mean by "splash" and "background" image. I know the splash from the manifest - and one image (hd or fhd) should be sufficient. Currently the web portal will terrorize you to upload all posters as FHD, something that seems like a bug

splash_screen_fhd is required
splash_screen_hd is optional
splash_screen_sd doesn't work

You can just go with splash_screen_fhd if you want, as it will be scaled down to HD dimensions.

mm_icon_focus_hd is required
All other _focus_ and _side_ attributes are deprecated

Perfect, thank you!

I just wanted to confirm this is the same with the SceneGraph channel. The following is the manifest, so is the below correct?

# Channel Details
title=Video Player
subtitle=Video Player Example in SceneGraph
major_version=1
minor_version=1
build_version=1

# Channel Assets
Not needed - mm_icon_focus_sd=pkg:/images/channel-poster_sd.png
mm_icon_focus_hd=pkg:/images/channel-poster_hd.png
Not needed - mm_icon_focus_fhd=pkg:/images/channel-poster_fhd.png

# Splash Screen + Loading Screen Artwork
Not needed - splash_screen_sd=pkg:/images/splash-screen_sd.jpg
Not needed - splash_screen_hd=pkg:/images/splash-screen_hd.jpg
splash_screen_fhd=pkg:/images/splash-screen_fhd.jpg
Not needed - splash_color=#808080
Not needed - splash_min_time=0

# Resolution
ui_resolutions=fhd

That's correct, as long as your channel scenes are based on an FHD (1920x1080) layout. If so, and you don't specify any other resolutions, the channel should automatically scale if running at a different resolution.

All the manifest attributes are documented here: https://github.com/rokudev/docs/blob/master/develop/specifications/manifest.md

To be clear, belltown's comment is about `ui_resolutions=fhd` setting, which is completely independent from the icon and splash screen settings. That is, if you design your UI layout for `ui_resolutions=hd`, it will still get re-sized to the actual screen resolution - and that has no effect to the icon/poster choice.

Nor does the choice of ui_resolutions affect the video resolution. That is, a 4k video stream will play in 4k on device with Settings > Display type = "4K UHD... ", regardless if you chose to position your UI elements in SD, HD or FHD units
