Shadow Map too big

All is OK in the shader map texture, but the is scaled (too big).

The coord texture:

mat4 bias = mat4(0.5, 0.0, 0.0, 0.0, 0.0, 0.5, 0.0, 0.0, 0.0, 0.0, 0.5, 0.0, 0.5, 0.5, 0.5, 1.0);

ShadowCoord = bias * projMatrix * viewModelMatrix * vec4(position,1);

Why in another example the textureMap coord is:

ShadowCoord = bias * projMatrix * viewModelMatrix * ViewMatrixInverse;

And another:

ShadowCoord = bias * projMatrix * viewModelMatrix * ModelMatrixRenderObject * vec4(position,1);

Please, does anyone can explain the differences? and Why do my Texture Map is scaled?

Thank you, best regards.
