I don't know if it is my eyes that aren't focusing fast enough, or wether the image itself DOES in fact does blur, but when watching a DVD on my 400Q I find that the image softens considerably when there is fast, sweeping vertical or horizontal movement taking place on the screen. It improves immediately when the action stops. Is it my eyes that are the problem? Has anyone else noticed this? If's not my eyes, how can I improve this, and what is the root of the problem? Would a progressive-scan DVD player help? Or something else? Thanks!
