Runs off left side of screen with a 2inch black vertical bar left on the right side. Can't read all the options so good thing I know where they are. I did the original install of 13.04 on another monitor then switched to this one. Looked fine on the first one. Not sure if that's the problem but thought it worth mentioning for troubleshooting. I would like to correct it because its driving me nuts with my OCD about perfection lol. Thanks in advance for any help or input.
