Why cant I get 400X800 resolution in my AVD

I am using Eclipse and if my AVD is set at WVGA800 The highest resolution I see is 320X533 with the title bar gone. If my AVD is set at WVGA854 The highest resolution I see is 320X568 with the title bar gone. The Emulator is set for Android 2.2 API 8 and I am using XPSP3

Why cant I get 400X800 resolu开发者_JAVA技巧tion?

When you set the android:minSdkVersion="4" android:targetSdkVersion="8" It starts the emulator in a lower screen resolution. by changing the minSdkVersion to 8 I was able to get the full screen resolution on my emulator.
