The registry settings in the KB article VMware KB: Settings tab is not available in the Display control panel of a View desktop in local mode, or using PCoI… also work in Windows 7 and corrected the issue for me.
I was having a heck of a time after I upgraded my dual monitors on a Wyse P20 from 19" to 22". I set the resolution in View on the desktop pool but only the first monitor had the correct resolution- the second monitor was less than the resolution on the original 19" monitors. I fiddled and monkeyed with all the settings I could think of with no success. After changing the registry key I was able to manually set the display resolution.
