As you can see in the images in the link below, my computer is telling me my display is using the aspect ratio 256:135, which is why I have the option to choose a resolution of 4096x2160. However, my displays specifications state that the display has a max resolution of 3840x2160 and an aspect ratio of 16:9. Which device is wrong, my computer or my display?
