I mean nothing is going to be perfect with this mod, or the LCD's that we choose. When McWill designs an Express LCD, it's going to look GOOD.. damn good and sharp.
However, I've installed an LCD from the link I posted and it's working great! I have to upload a pic to show. The screen doesn't roll and the image is sharp.
With a 2.5" screen, for sure the picture will be more compressed so you're less likely to notice *any* sort of pixelation.. not that you'll notice much with the 3.5" screen either. But if you want a clean/stock look, keep the 2.5 so you don't have to cut the case.
But where can one find a 2.5" LCD screen? Those seem to be as rare as unicorns at this time!
