640x480 works nicely on my 701.
if 640x480 is not listed in your settings options, go to
display properties > Settings> Advanced> Adapter> List All Modes
Then select 640x480, True Color (32bit). Make sure you select the correct Hertz or your screen will go blank on you. For me 60 Hertz works fine.
This will make your windows a lot easier to read. However, if you are running any software that won't fit a 640x480 window, you can use a program called rezchanger that will allow it to change the screensize when you launch the software, and return to the previous screen size when you close it.. Similar to what road runner does..
