dell p2418ht monitor does not have stylus mentioned in its default spec. But I read online few people said they are able to use any stylus and even videos, and one even mentioned surface pen. I have a surface pro 4, I know active part does not work, but just touch part should work. It does not. It only reacts to larger touch like the eraser of surface pen, but not the pointer. Is that something we can fix by software or settings? Dell driver does not have anything too.
