I just installed Xubuntu 13.04 with Windows 8 dual boot on my Dell XPS 13 (2013) Ultrabook.
All is good, except when I connect my ViewSonic HDMI 1080p Full HD External Monitor, it appears as Display DP1 in Xubuntu with a maximum screen resolution of 1024 x 768.
In Windows 8 I can set it to 1920 x 1080. Any suggestions?
Thanks in advance!
