Roku TV RGB issue

Brand new Sharp Roku TV is in RGB full always when using 1080p 4K or any other resolution but 1440p it is in limited RGB the TV clearly doesn't support RGB full range
is there some advanced picture menu to force it to limited RGB in 4K i cannot return the TV

Re: Roku TV RGB issue

System-advanced settings then advanced display settings.  Ultra regular display menu usually will give a force option if you choose something it doesn't like.
