I have develop a Group under the size of 3840*2160, but right now, I need to put it on 1080P screen, so I did this:

I set the root application-profile's screen size <1920, 1080> (the black rect), and then I put a 1920*1080 warp group(the red rect) on the root application. The warp group's "Group" is the 3840*2160-group I developed(the green rect).
It works fine in EW IDE simulator, but when I upload it in to device, it shows error number 179: Invalid size (width=3840, height=2160) of bitmap to create.
Can EW support the usage like this? If no, is there another better way?
Looking forward to your reply. Thank you !
