Dell Inspiron 7000 won't recognise Dell U2412M Monitor on Windows 10?

I have just bought a Dell Inspiron 15 7000 15.6" Laptop

...and I want to use my Dell u2412M monitor, to extend the screens for my workspace ( or simply use the bigger monitor screen).

To achieve this I am using an HDMI cable with an HDMI to DVI adaptor to plug the cable into the Dell monitor.

I've tested the cable on my old Sony laptop using HDMI to DVI and it recognises the monitor and works (my other laptop was running Windows 7).

However the new laptop won't recognise or see the monitor at all when I plug in the HDMI cable?

I have checked under "manage my devices" and the graphics card driver seems up to date on the laptop.

Is there something I need to download to make the monitor work please as I assumed it would plug and play.

Many thanks!!!
