Using Groom and nDisplay

I currently have a project where i have a lion that is using groom to add on the fur for the mane and whiskers. If i render out my animation using MRQ and a Cinecamera then the fur and hair looks perfect. As soon as i view it through the nDisplay or try and render it through MRQ and nDisplay rendering the quality of the hair drops significantly, is there a reason for this or a way i can get around this. The reason I am using nDisplay as this is for a large corner screen so i need the animation ‘projected’ onto the screen from a certain perspective. Any suggestions?

The top is the export from the nDisplay, the bottom is an export through the cine camera. Can anyone explain why the groom suddenly drops quality when using the ndisplay export settings
