Changhong UD42YC5500UA faster LCD driver

Hello,

The author of the teardown mentions a faster LCD controller that would be available on alibaba, but I can't seem to find any... Does anybody have info on replacing the Changhung's guts for a latency-free 4K experience?

The Panel on the UD42YC5500UA i have here is a C420U13-E1-L(G1) (I know...)

Thank you,

- Charles
