Hi,
I have just opened your Aspect.dt1 image on Udig 1.2.M2 and it is properly displayed.
Your image has size 4x7 (28) as you have reported and the displayed image has the same size.
I guess that what are you talking about the image having only 18 grids (3x6) is due to the darkness of the pixels with lower values ---> the pixels of the rightern column and lower row.
Those dark pixels have values as 190, ... ,-1 which are lower than 2100, 2200,... (the values of the brighter pixels).

Can you confirm that what you see is similar to my screenshot? In that case, the rendering is working fine.
