Touch Screen horizontal dead zone

Hello I have followed the I fixit instructions as well as others and replaced my faulty sp4 screen with a brand new LG sp5 screen (screen displays perfect) I have also replaced the LBoard (ntrig) with a new one. When I'm in Windows 10 I have a 2 inch horizontal dead zone about 1/4 of an inch down from the top of the screen. Neither finger or pen work in this area,

If I boot in uefi it demonstrates the same behaviour,

Note1: I have also fitted my original ntrig (Lboard) aswell and have the same problem.

Note2: I have run all diagnostic test in surface Diagnostics, done fresh restore on Windows,

Note3: I have not yet replaced the digitalizer cable.

Is it possible I have a defective screen or digitalizer cable?

mrkeshin88 since this "2 inch horizontal dead zone about 1/4 of an inch down from the top of the screen" does not change, and it is consistent within and without your OS, it appears as if you have a failed digitizer. You would have to replace it and recheck

That's my thoughts, I have contacted the supplier as this is a brand new screen I have purchased and installed

I am experiencing the same issue; it appears to be a problem with the touch digitizer. Could you kindly provide any links where I can purchase a new digitizer for the Surface Pro 5th generation model?
