You may have luck using third party tools that change the windows screen mode like
QRes or
NirCmd (I found them through the search), because the access to control panel does not control access to modify the screen resolution.
If at all you happen to use one of the above mentioned ones, this is the syntax.
QRes.exe /x:1024 /y:768
nircmd.exe setdisplay 1024 768
Hope this helps.
