Inspiron 15 7000 not recognizing Dell U2412M Monitor

I have connected an HDMI cable to the new Dell laptop which runs windows 10

I have inserted an DVI to HDMI adapter into the monitor and plugged in the HDMI cable.

(I want to extend my workspace on my laptop onto the monitor).

I've tested the set up of the cable and adapter using another laptop running Windows 7 and it all works fine.

However, my new Dell laptop does not seem to recognize the Dell monitor.

Please can you advise solution/s? 

Thanks
