5 inch Display driver?

I have a 5 inch 720x1280 HDMI IPS LCD Display which I am using as a second monitor on my windows 10 pc to display system hardware monitor software. Now the problem is in windows 10 it comes up as a generic pnp monitor which means I can not change the screen resolution.

So is there a windows 10 driver anywhere or is the problem I am using a mini display port to hdmi adaptor and then an hdmi lead to the 5 inch monitor would it be better if I just used a mini display port to hdmi lead without using the adaptor.
