Displaying the raster's spatial resolution
The spatial resolution of a raster refers to the size of the cells in a raster dataset and the ratio of screen pixels to image pixels at the current map scale. For example, one screen pixel can be the result of nine image pixels resampled into one—a raster resolution of 1:9. In this case, every screen pixel has to display nine raster cells, meaning the image is not as clear and detailed.
A resolution of 1:1, however, means that every screen pixel is displaying only one raster cell. If you zoom in closer than a raster resolution of 1:1, you won't see more detail in that image.

To view a raster dataset at 1:1 resolution, right-click the raster layer in the table of contents and click Zoom to Raster Resolution.
