Note 4 screen problem

Hi despite my limited rooting knowledge I thought I'd try a beta test for a Rom. I downloaded the kernel and bootloader I needed to flash and did these via Odin. I flashed the Rom and it booted fine, but now my screen will not work correctly. I have to press and inch above whatever it is that i'm trying to press, even with the s pen. When I realized this problem I wiped the phone using TWRP and flashed Cm again except the problem was still there once the phone booted. I have now wiped the phone and flashed stock 5.1.1 onto my Note 4 and the problem is still there. I'm really starting to panic now. Can someone help?
