I have a Samsung SyncMaster 957p that would need some focus adjustment,
but I can't seem to open the case.

There are two screws near the bottom. Opening them makes the bottom end
loose, but the top seems to be as fixed as ever. I'm afraid I'm going to
snap some hidden plastic clips (or something) off if I just try to force
it. Is there some known trick that needs to be employed in order to open
this case?
