Tunnel Vision only affects active matrix monochrome/grayscale displays. Anything passive matrix and active matrix color doesn’t have the issue. We don’t even know if every active monochrome is affected because the Apple laptops with them only used hoseiden branded ones. If any PC laptops shipped with one not made by hoseiden, it would be interesting to see if they also have the fault.
Anyway, that means that the 100, 140, 145, 150, 160, 165, 190, etc are not affected because they’re all passive matrix. The only apple laptops affected are the 170, 180, 540, Duo 250, Duo 280 and the portable. Although, the portable doesn’t get it as often as the PowerBooks do for whatever reason. It does happen though. It’s been confirmed that the Portable, 170, 180 and the 540 have hoseiden screens, not sure about the Duos. I also know that Hoseiden made the screens in some 5300cs and possibly others, but they don’t have the issue because they aren’t active grayscale or monochrome.
People often confuse vinegar syndrome (polarizer failure) with tunnel vision. They aren’t the same thing and vinegar syndrome can be fixed by replacing the polarizer layer. Tunnel vision is an issue with the LCD itself.
