Image in V-ray next dome huge in scale to my model

Hi quite new to this but can’t find an answer anywhere. I’m trying to load a 16k hdri from hdri haven to my dome but it is coming up huge in scale to my model.
Even using a scene where the landscape is far away all it does is bring the landscape super close and is blurry.
Any help appreciated!!!

See my reply to your comment on the other thread.

Hi, I think I’ve worked it out. I’ve changed the mapping to screen and it seemed to do the trick…(if this sounds right).

Plus I imported a 4K image.
