Thanks for your reply.
If you navigate to the Windows 'control panel' and have the control panel set to show all the icons contained in it (in other words, when you open control panel in Windows 7, you will see a drop down menu to the right hand side of the window, this menu has three choices to choose from, by category, small icons or large icons, choose either large or small icons, now you should see a Nvidia control panel icon listed alphabetically in the list of shortcuts that are now visible) Please double click this Nvidia icon, once the Nvidia control panel appears, there should be options listed in the control panel's menu for adjusting the various screen settings.
Look for screen resolution, try making the adjustments here to the one your interested in setting it to.
If you still can not go to the higher settings, please be advised, Windows 7 has a setting that prevents screen resolutions that your monitor does not support from being available in the slider bar for screen resolutions.
To change this, right click your desktop, choose screen resolution, look for ADVANCED SETTINGS, click ADVANCE SETTINGS, look for the MONITOR tab, click MONITOR tab, look for a check mark in a box where it states Hide modes this monitor can not display
Once that check mark is removed, your slider bar should now show more screen resolutions.
If you are lost as to where that check mark is located, I will be happy to post a screen shot of its location.
