Hello We use this Virtual machine Windows Datacenter (64 bit) for UI test requirements. We have automated UI tests using AutomateQA TestComplete software. They are recorded with resolution 1280 X 800. Now when we execute them with TestExecute (stripped down version of TestComplete) - the tests do not find any GUI objects. We have equivalent tests in other 32-bit environments which run fine - some of them run on 1280 X 1024, after changing the resolution to this value using 3rd party utility. (I have seen that this utility eventually use ChangeDisplaySetting function) But this datacenter VM does not succeed in changing the resolution to my desired value. Nor do I know what resolution values it supports. Note also that my requirement is strictly to run these tests in remote session - without any user session (nightly build infrastructure should automatically run them) alive. No RDP, nothing like that. Please provide some solution urgently, as I have been playing with this since more than a week. Thanks, -Vividcode

Hi, Please check the following post. Resolution between Host machine and VM http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/2bae52f0-be76-4332-9dab-45baab1da892 Best Regards, Vincent Hu
