Low-Level graphics after crash

Hi!
I was plotting some graphs for my homework (nothing fancy just 2D graphs) and I restarted MATLAB (for whatever reason). When it started up again, there was a message, which said something about switching to another graphic displaying mode due to a previous crash (note: I did not see the program crash, it just said it did) it also mentioned opengl in that message. I can't remember what it said exactly, because I disregarded it that time and it didn't show up again.
Bottom line is, that my graphs are now pretty low-res, made up of long straight lines, but before this it didn't have any problems displaying nice sine waves. I tried switching around the opengl modes (hardware/software), but it didn't fix the issue. Can anyone suggest where to look for a fix?

I found the error message on another thread, but now reading this, I think the opengl hardware command should have fixed it, but for some reason it didn't.
Warning: MATLAB previously crashed due to a low-level graphics error. To prevent another crash in this session, MATLAB is using software OpenGL instead of using your graphics hardware. To save this setting for future sessions, use the opengl('save', 'software') command. For more information, see Resolving Low-Level Graphics Issues.

You might perhaps need a graphics driver update.
