SceneGraph Video - does it really play 4K resolution?
Hi All,
I have been experimenting with 4K content on Roku 4 within SceneGraph and noticed that I can't seem to see the difference on a 4k TV between HD and 4K versions of the same content.
I have a suspicion that roku down-scales video resolution to HD, even though content is played in 4K full screen. My concern comes from the following facts:
- According to docs, roku 4 SceneGraph GUI is rendered in 1920x1080 resolution
- According to docs, when setting Video node width/height to 0 - "If set to 0.0 (the default), the video play window is set to the width/height of the entire display screen."
- Within SceneGraph a display screen is 1920x1080, so would this mean 4k video will be played within the HD container? thus being down-scaled?
As I mentioned previously, I can't see the difference between HD and 4K content on Roku 4. Of course, there are multiple factors like video quality,tv quality, eyes quality 🙂 and so on. But the question still stands - how can we verify this?
Roku dev team - I would appreciate timely response! Thank you
