    The log-on screen and super user display just fine on my Mac Mini connected to my LCD TV.

    But I experimented with the resolution while logged in as my default user & now the screen is black.

    I've read about resetting the Mac Mini video settings or OS reinstall, but this applies to all video on the computer.

    My issue is just for one user.

    Thanks in advance for your help! Marc

    If you have a second display, connect the unit to it and correct the display preferences and then try again with the LCD TV.

    You have set the screen resolution to a setting too high for your monitor. I like the other fellows suggestion. Hook it up to another monitor and reduce the resolution before hooking up to the working monitor.

    I seem to recall having this problem. I hooked it up to a Dell 24" display to fix it.

    Thanks for your help.

    Before I disconnect my Mini Mac & move it to my office, or disconnect my monitor & move it close to my Mini Mac...

    Is there some way, as Admin, to edit the system preferences of a user?

    I could just blow this user away & start over...

    Thanks again!

    I guess it depends how much time you have invested setting up the user. If you have an established user with files and programs, I'd think twice. If you just set the user up, then it's no biggie to do that again.

    As far as I remember, account preferences that can be manipulated are access to programs, time restrictions, web sites etc.

    There is a preference (plist) somewhere that holds the resolution. I would think a google search could find this.

    Also if you unplug the monitor cable while the computer is on then plug it back in, this tends to reset the screen.

    If you have another computer you could screen share in to this one.

    Can you change it from the safe mode? I think you hold shift while booting to go into safe mode.
