Speaking of pieces of paper, try this:

Display that image on your screen, and hold a thin piece of paper 
against it to cover the whole image. This will physically blur the black 
and white lines, eliminating visual perception issues.

On a CRT, in which each scanline is produced independently, this should 
give /exactly/ 50% brightness (of what comes through the paper of course)

I didn't think this through for LCDs; there might be some side effects 
of light scattering between pixels and being affected by the other 
pixel's liquid crystal, but if one considers this an issue, the sheet of 
paper should allow to make the test with a coarser pattern. (Dynamic 
backlight arrays might really make things complicated though.)
