Yesterday, a fire started on the Internet regarding visible scanlines appearing on the PSP-3000. It seems that the scanline problem is a feature of the new LCD screens. By improving LCD response time to reduce ghosting, the horizontal-line phenomenon becomes more visible. Sony’s official response is rather lackluster, and essentially says that you are going to have to deal with it:
“On some occasions, scan lines may appear on scenes where brightness changes drastically, due to the hardware features of the new LCD device on PSP-3000. Installed with this new LCD device, PSP-3000 offers more natural and vibrant colors on its screen, but the scan lines have come out to be more visible as a result of improving response time to alleviate the afterimages on PSP-3000. Since this is due to hardware specification, there are no plans for a system software update concerning this issue.”
Have you noticed the scanlines?
