I can how happily use my Intel NUC in a reasonable fashion until FreeBSD 11 comes along. The link above was most helpful. Here are the steps I had to take to get the proper resolution: 1) Boot into loader prompt. 2) Type "mode" to get a list of available modes. 3) Choose a mode and set it. 4) Back at the loader prompt, type 'gop get' to see what resolution that mode permitted. 5) Eventually, I discovered that setting to mode '0' would result in a 1920*1200 option when the 'gop get' command was executed. 6) Boot the system and all is good!
