Have you installed all your graphics card drivers? If not then it will be running from Intel HD Graphics. Go the MSI/NVIDIA website to download the correct drivers for your graphics card. Also make sure the display is being powered by the graphics card and not the integrated graphics. Usually the graphics card is closer to the bottom of the case, so plug your HDMI/DVI/VGA cable into the the correct port near the bottom of the case, as otherwise you will be using integrated graphics.
Hope this helps.
