That's a very broad description. Can you tell us what the text is about, what mood and tone you're trying to achieve, how the text will be set, and whether it's a book, newspaper, website, leaflet or poster.

Also perhaps if you suggest other typefaces you're considering you'll get the discussion going a bit.

The appearance in display screen but its a universal issue.

My question is exactly the same on this issue: A sans serif font that pairs well with Soho Gothic: http://typophile.com/node/66026

Anyone?

Your question is sort of like asking "what should I serve with chicken?" Without knowing if it is KFC, Bombay Chicken Curry or Lemon Pepper Cappellini with Chicken Cutlets Brasciole one can't give a meaningful suggestion. That is why you are getting no responses. Hope that helps.
