i think the job you are doing is amazing complicated,in the china sellers from aliexpress says that if i install a new screen 4k in one laptop that dosnt comes with it i can broke the laptop by the pinout,in any case i dont believe it,about the 40 edp cable i think every link 40pin edp its compatible because its a standard and the pinout must be the samein every link and every laptop motherboard,i have the original auo109b that comes with my gt73vr 7rf 4k model and it looks amazing men,its incredible the rich colors in the mate version,in any case i where looking info about the sharp screen of the razer pro 4k,it seems like this laptop has a even one better screen
LQ173D1JW33 SHARP GLOSSY
the experts says that is the best screen on the market,its available in alixpress and others,i asked and there is no stock but maybe in the future,the challenge is fit one screen like this version glossy on my laptop,make it compatible and fit it in the case
