More about MTG test data
Another one about test data of MTG:
Size of VIS images is 11136x11136, but satpy creates images of 3712x3712. Somewhere the image is resized? That's not done explicitely in the script I use.
The image itself has a resolution of 3712x3712; the test data contains pixelsets of 3x3 having the same value. Of course, with real MTG-data this will not be the case.

I do not think that anything is wrong. According to this document
distributed with the MTI1 test data we have:
• Full images of the (rectified) Earth disk as seen from geostationary orbit over the (0,0)
• 16 simulated channels
• 2-D array sizes: 5568x5568 pixels for IR channels and 11136x11136 pixels for VIS-
If you you take my 'full_scan' of MSG it is resampled GEOS 0° 3712x3712 like MSG4. If you resample native you will probably get 5568x5568 depending on the composite at hand. If you display a single high resolution channel native you should get 11136x11136. In fact that is something you already get as native image of channel 'HRV' of MSG2 or MSG4 ...
