    Report with output from
    Code:
    xrandr
    And which display utility do you refer to?
    Which desktop environment are you using?

    If you check xrandr you should see other display modes available, and you should be able to set a preferred mode via your dekstop's display utility on a permanent basis.
    Fine. HOW do I do that? How do I "check xranddr" ? And what display utility do I use?

    Thanks, Bob

    Found the problem. When I used Settings, System Settings,Display Monitor, I found I could pull down the resolution settings, which then worked.

    That is the display utility I was hinting at, but that's why I requested the desktop environment you were using first

    The CLI utility can be used to provide the detected display modes as well.
    Code:
    xrandr
