Try starting over - power everything down, disconnect the monitor, remove power form the monitor and wait at least 30 seconds.
Power up the monitor and see what options are given (language, resolution, ???)
I'm not sure but that should set the defaults for the monitor - from your screen it looks as though the pitch is not right.
Are there buttons on the monitor or is just on-screen configuration?
I can adjust my monitor using buttons on the bottom right of the frame (near the power button)
Once you monitor is 'reset' power it down and reconnect it to your machine.
Here's the manual that I found for Samsung SyncMaster B2230 (in it there are settings for B2230, B2230N, and B2230W)

The menu is in 3-14 (see reset)
From this page which has some help topics at the bottom.
If it Windows, try setting the Samsung as your primary - do not clone it.
I recall a similar issue where I had to reset the DPI scaling (your taskbar off the bottom reminded me of this). I think Windows gets confused and you have to 'toggle' the setting higher, then lower or visa versa.
Also check your resolution in Control Panel Display - I think I also had to drive that up or down before the issue was 'resolved'.
But start from a known base - reset your physical monitor, then twiddle with Windows settings (I'd venture it is not the GPU)
Good luck - that's all I have to offer.
