External monitor display not aligned

    I am on a MacBook Pro (2009) running an external Samsung LD109G monitor (1360x768) via my small video out port(can't remember what it is called) and running it through an adaptor into a normal RGB monitor cable.

    It usually works fine, but this is the 2nd time this has happened. Last time it just popped back to normal oneday. I use both my macbooks screen and the samsung together with my main toolbar on the Samsung. Now there is about 10-15 pixels of black on the top edge and the left, while part of the screen is being cut off on the other two sides. I cannot find any alignment adjustments within the monitors menu, and nothing to say on the system prefs. display area. I have tried unplugging and replugging, restarting, mirroring/unmirroring, recalibrating the color etc. nothing changes it.

    If I downgrade the resolution to the next choice of 1280x720 then it not only lowers the resolution but a somewhat opposite alignment problem occurs. The bottom and the top of my desktop are in alignment with the edge of my screen but the whole image is off to the left showing -'em preferences' of the 'system preferences' menu name and a big black strip on the right side.

    I only have a couple more ideas of things I could try such as repairing disc permissions, and changing the main menu from the external to the computer screen then back. But I seriously doubt that these fixes will do anything.

    I could use the USB to drive my display but apparently the OpenGL software will not work this way.
    Also I have yet to find a USB hub that can give me more then two USB slots that will work for more than five minutes. Any ideas on this? Since thunderbolt uses the same size plug/port as my monitor output, is it possible to use it as a thunderbolt i/o???

    You may wish to drop the attitude if you want people to volunteer their time to help you.

    Sorry if I missed it in your post, but did you try dragging the monitors in system preferences > Display to allign them?

    Thank you so much for offering assistance. Yes I believe I did like you said. I tried switching the sides, moving the control bar, rotating, plugging and unplugging, tried SwitchResX, Changing resolutions, switching monitor from digital to analog,

    Nothing changes...

    I don't know what else I can do.
