Considering the Touch Pro and Diamond has a native VGA (480x640) resolution, Android looks really “small” on such a high resolution screen. In order to fix this, just add the following lines to your startup.txt within the quotes:

mddi.width=320 mddi.height=480 lcd.density=240

Keep in mind that this should be placed within the quotes in the startup.txt file, so you would end up with something like:

set mtype 2039
set kernel zImage
set initrd initrd.gz
set ramsize 0x6000000
set ramaddr 0x10000000
set cmdline "root=/dev/ram0 init=/ console=tty0 mem=76M msmsdcc_id=3 zmgdevname=/dev/mmcblk0p1 imgdevnum=1 imgdir=/ msmts_calib=0x81.0x393.0x358.0x7D clock-7x00.a11=500 msmvkeyb_toggle=off mddi.width=320 mddi.height=480 lcd.density=240"
boot

Save and boot into Android and enjoy a lower resolution which is easier to handle!
