I ordered XPS 8940 on Amazon: https://www.amazon.com/gp/product/B09D7JH9ZC/ , there is no back photo. I went to Dell Official website and check XPS 8940 back photo (attached), before placing the order. Here is Dell official page: https://www.dell.com/en-us/shop/desktops/new-desktop/spd/xps-8940-desktop 

Now I have received my XPS 8940, which is different from the photo posted on Dell Official website. My PC has much fewer ports(see attached), how many monitors can my PC connect to? Why my XPS 8940 is different from the photo posted on Dell website.

Thanks.
