The revised PSP model boasts an increased colour range, five times the contrast ratio, half the pixel response time to reduce ghosting and blurring effects, and anti-reflective technology to improve outdoor playability, but the interlacing issue has caused concern. So much so that Sony has responded publicly to the complaint:
Speaking to PSPFanboy, SCEA state that: “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 colours 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.”
Today, sees update version 5.01 of the firmware made available which fixes a bug from the previous version relating to download issues on the Memory Stick Duo
