Can some explain the "hz" parameter?

Oh, so like Graphics 640,480,32,-1 would let the o/s driver choose a hz rate for the display resolution for you? I didn't know it could do that.

Also, yeah, pity that some drivers do not report properly the hz rate or the vertical blank event. What can you do. On my iMac widescreen display where you have stretched versions of 4:3 ratio resolutions, in addition to normal 4:3 ratio resolutions, there is no way to distinguish between then in the list of display modes. It would be nice if BRL added ability to read the hz rate into the list.
