There were a few points where the screen lines would jitter but that may be down to my cables not making a good connection. After several minutes of gameplay the issue corrected itself and the screen worked flawlessly. The length of the touch sensitive brightness control doesnt allow you to put it wherever you want, but it fits absolutely perfectly in the top of the shell, allowing you to adjust brightness by just tapping or running along the top of the NGPC with your finger. The new glass bezel also perfectly compliments the screen (if you chuck screen bracket like I did), so centering the screen and securing it with tape is optimal.
Overall as good as I expected it to be.
