Resize environment image

Hello. Can someone tell me if there is possible to resize the environment image which is a custom import jpg file.

This becomes a spherical wrap around the model, but appears as background with wrong aspect size ratio,

When tried to use Edit Scene Advanced and resizing Floor Size/Rotation nothing happens. I also see that there is a big difference in background size (zoom) apperence depending on using RealView or PhotView360.
