Nope, that did not help. The data itself is valid. I think there's something wrong with the way nVidia's OpenGL handles 16bit (at least I read that somewhere when searching).
Since 16bit image display is not an issue in the first place, I guess this one is resolved.
Thanks for all the input.
glTexImage2D(GL_TEXTURE_2D, 0, GL_INTENSITY16, width, height, 0, GL_LUMINANCE16, GL_UNSIGNED_SHORT, Data());
should generate GL_INVALID_VALUE or GL_INVALID_ENUM because GL_LUMINANCE16 is not in the book. You need
glTexImage2D(GL_TEXTURE_2D, 0, GL_INTENSITY16, width, height, 0, GL_LUMINANCE, GL_UNSIGNED_SHORT, Data());

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
Thanks for that, with LUMINANCE it's working now for all 3 monochrome modes.
One last question though, why does it work with MONO12? I specify it as GL_UNSIGNED_BYTE, so that'd be too little, but UNSIGNED_SHORT would be too much. As Internal format I set it to GL_INTENSITY12, so my guess is, this overrides the other value, but according to documentation the 3rd value represents how that texture should be used, and not what the data looks like?
Edit: turns out, an error in my code used the default conversion to BGR, so the display of Mono12 actually never worked.
