Can the scene with different aspect ratio ......?

[alfred]

That is to say,I set the aspect ratio with 1902x1080,but after finish editing, I acknowledged that it is a 2x2 display wall with the aspect ratio 3840x2160. Without changing the ratio(1920x1080), can the scene be displayed on the display wall with 3840x2160? Thanks!

It seems a stupid question maybe I may the question should be asked like that-- before starting,I should make sure the display aspect ratio first, and set the scene with the apporiate aspect ratio in Ventuz,right? In other words, the aspect ratio can not be changed after completing, right?

you can change the aspect ratio at any time.

however, this will not be without effect on your content, which was built for the original aspect ratio. What effect that is, for example lots of black space or letterboxing or scaling/squeezing is up to you depending on how you set up the scene.

Perhaps I am misunderstanding the question, though.

Add a Projection Node with FoV in front of your content to overwrite the (invisible) default one in your scene. You can directly adjust the aspect ratio there, Like Eric said, it might have a negative effect on parts or even your whole scene. But you can add as many of those nodes in your scene as you want to adjust elements individually if you have to.

Just a quick note: both resolutions (1920 by 1080 and 3840 by 2160) do have the same aspect ratio

Adding Projection node, it means that the scene may looks better, but in face the scene's ration can't be changed,right?
