Windows 10 will not detect second monitor and just mirrors the display

Hi

My son has a gaming pc with a new NVidia video card and running Windows 10 I believe and we have just purchased an ultra wide gaming monitor for his birthday.

He wishes to keep his AOC existing monitor and have 2 monitors up and running and to extend the display and not mirror.

We have connected both via HDMI using I think the term is a HDMI splitter purchased from Amazon.

We have updated the Nvidia drivers as suggested and ensured all the cables are connected but when we go to Settings and additional display it does not detect the second monitor and the display is mirrored with no option to extend.

Searched on the web for half a day with no real suggestions. I use 2 monitors at work without issue so cannot explain to him why it will not detect the 2nd display.

Any help would be greatly appreciated. Thanks.

 

mirroring 2 2560 monitors to 2 1080 tv's

My quadro 600 has only 1 HDMI and 1 DVI, which I'm not a fan of. I'm open to suggestions to a different video card.

What I'm trying to do is say for example, you have 4 different displays set up, 1 and 2 would be the 2560 monitors and 3 and 4 would be the 10080 tv's. i would like to mirror 1 to 3 and 2 to 4.
