You need to right click the image, and click on 'Build DXT'. There'll be two size fields. Change those to what you want (in this case something bigger for more detail), and upload your texture. Change the 'Sharpen' option to none. When you're done, click 'build' in the corner.
Don't forget to update all sizes before committing. Then you should be done.
