What program are you making it/saving it in? And when you say 'low quality' what are you seeing exactly? Sometimes, if you save in dementions that don't match your desktop resolution, and you try to make it your background, it will distort the image to fit your desktop resolution, causing it to look bad. Also, if the resolution is bigger than what your desktop resolution is, and you try to open the image in a viewer, it will have to shrink the image down to fit the screen, causing it to look pixelated. When you are looking at your image in your viewer, make sure it's at 100% (not the size of the screen, but 100% of the file's resolution. It may be bigger than can fit on your screen at one time). Once it's at full size, see if it looks clearer.
BTW, the attached image looks clean on my screen which is 1440x900 reduced to fit.
