Hi @JacobP Msn is 30029546 I have not been able to capture an image of the vertical line as it flashes up and goes away too quickly. The line always appears in the same place about two thirds across the screen from left to right, I am slightly colour blind but it does look to be red in colour. Strangely enough, since I posted this thread it has been showing less and less to the point that I hardly see it any more. Thanks.
