I recently faced the same solution but I contacted the customer support of HP using live chat and they solved it for me. The sticker said NVIDIA GeForce GTX 965M but when I checked on the laptop, it said Intel(R) HD Graphics 530. What you need to do is (for Window 10) right click to the Start menu (bottom left corner in desktop screen) then choose device manager. There should be something pop up right after. Try to find Display adapters in it, and press the V arrow to check all the available adapters (graphic cards) on your desktops/laptops/notebooks
