Why is the background image less smooth on the phone?

Question

I've just downloaded Gamestate code from create.msdn.com, and as you can see from the image below:

The result is less smooth then the image imported to visual studio, how do I increase the quality?

Are you running your emulator in scaled mode? Try putting it at 100%. The other thing may be due to colors. This also may be part of the NoDo 16bit color banding issue: 1800pocketpc.com/…
same result on my phone and emulator @ 100%. will read thru the 16bit thingy
@Nate Boss read thru the 16bit NoDo thingy. First off: its no do, not recommendet. Second: i get this bug on my emulator, isnt that silly? Really breaks ALL my development, so i need a fix :(
The fix will come out later supposibly. For now, all you can do is work with 16bit colors instead of 32.
@Jon Are u serious? That means no larger textures with a gradient will look nice at all on WP7? Im shocked... really.

Set

graphics.PreferredBackBufferFormat = SurfaceFormat.Color;

in your Game constructor. XNA sets the backbuffer to SurfaceFormat.Bgr565 (16 bit) by default.

You should be able to get a better looking gradient by dithering the source image down to 565.
