** Description changed: 4K monitor is not properly detected. using xfce desktop "Display" utility, my monitor is detected as "Goldstar Company Ltd 27" with a resolution of 3840x2160 and 60.0Hz The actual monitor is an LG 31MU97-B Black 31" with a resolution of 4096x2160. I'm pretty sure the Monitor's resolution was properly detected in 15.10 (4096x2160). It was called "Goldstar Company Ltd" but I do not recall which size was detected. (27" or 31") I remember seeing a 4K youtube video in 15.10 and noting the black bands on each side of the display, due to the difference between 3840 and 4096.
