My new Pioneer 5090 is arriving tomorrow hopefully and while i'm excited, something has been bothering me over the last couple of days...screen wear. Basically it's going into a dedicated room and will used purely for watching films on, no TV or videogames at all. My concern is that with that in mind, 99% of films will be either 2.35/2.40:1 or 1.85:1 and there are therefore going to be bars top and bottom of the screen were the phosphors are literally getting no use at all. If i follow the sensible running in precautions when first using the screen, how many hours is it likely to be before it's noticeable that it's had less wear in certain locations? To be fair, it's ordered and paid for now and so there's nothing I can do about it anyway. It's unlikely to get more than perhaps 10 hours a week usage though in reality, so if we're talking more than 4 or 5 thousand hours then i'll likely have moved on by that time and my mind will be at rest.
