I just reloaded a client's workstation that is running Windows XP and Quickbooks 2009 Premier Accountant's edition. The workstation has a 26" LCD Westinghouse monitor which uses the generic plug and play drivers. The onboard Intel chipset recognizes the monitor and a maximum resolution of 1920 x 1200. The display works properly at this setting without any issues.
However, when Quickbooks is opened, the screen resolution changes to 640 x 480. Sometimes it changes back and sometimes it has to be manually changed back. I've updated the chipset drivers and confirmed that there are no manufacturer drivers for the monitor and the issue is still happening. Does Quickbooks have a maximum resolution that it can operate at?
I'm at a loss with this issue. I've seen this before with hardware going out but this is only happening when opening Quickbooks. Also, there are no errors being logged in the event viewer.
Any help will be greatly appreciated!
