Just got my PSV a couple days ago (HK, 3G) and realised that the screen shows vertical lines when displaying a grey/brownish picture. Apparently its common for OLED screens but its kinda distracting. Sony should have opted for an IPS display or AMOLED. My PSV screen taken from my iphone, PSV brightness lowest: http://i241.photobucket.com/albums/ff131/MetroidSlayer0/photo.jpg You notice several vertical lines all across the screen. I'm not surprised if others share this problem too.
