[GRASSLIST:1791] Re: [UW-GIS-L] "resample during display" stopped working

[David Finlayson]

There are two places that raster resolution is set for exporting, the 
first is under:

File > Page Set up > Map Setup > Output Image Quality

The second is under:

[Grid] Properties > Display > Display Quality

Both affect the output image resolution (balancing file size with image 
quality). Try setting them both to high settings and see if that helps.
