This is a used 10" display. It has the typical northstar screen delamination issue. When its on a white background it's easy to see. When the background is colored, it's not as easy to notice. This display was used as a slave unit or a repeater. It is very simple to convert it to master if that is what you're looking for. the unit was working correctly when it was removed. It is being sold for parts not working due to the screen issue.
