When I downloaded the driver from viewsonic site, it gave me an error about not working or whatever.
However, it includes a icc profile that for some reason extracts into the C drive, not even to a particular folder, just the C drive. A whole lot of viewsonic icc profiles go there also. Have to scroll down to find the one labeled XG2401 Series and set as default manually. It seems pretty good. The whites are much more white.
