Questions[screen-resolution](server)

When I connect to my Windows Server 2012R2 Azure VM via RDP, I have resolution 1600x900, which corresponds to my client PC resolution. However, when I run selenium UI tests on this machine with VSO agent, they are failing because screen resolution for agent session is 1024x768. In Device manager I can see that display adapter is Microsoft Hyper-V Video. When I access Screen Resolution section when connected via RDP, I can see only my resolution selected and grayed out and also message "The display settings can't be changed from a remote session".
Is it possible to change default screen resolution for Windows Server 2012R2 running on Azure VM?
I tried adding DefaultSettings.XResolution and DefaultSettings.YResolution values to registry but it didn't help.

Is there anywhere that screen resolution can be set for the users at the domain group policy level?

Our environment prominently featuers an outdated but absolutely mission-critical Win32 application that is not dpi-aware. It is optimized for an 800x600 display. Most of our users now have 17"-20" displays with native resolutions ranging from 1280x1024 to 1680x1050. However, they still operate these displays at 800x600 because the text in this legacy application is otherwise too small. Of course, it also means that nothing quite fits on the screen in Office 2007.

Most of our workstations still run Windows XP, but some are on Windows 7 and there are more to come. About one-third of our users run the app remotely via MS Terminal Services, and the remainder run it locally.

Is anyone aware of any method that could be used to scale this specific application to about 170%, so that it would fill a 1280x1024 screen, without affecting other applications that work best at the display's native resolution? I know how to do this in Mac OS X, but I have never found a way to do it in Windows.

Of course, this ideally would be something that we could push out via Group Policy. I suppose we even could create a custom MSI package to re-deploy the legacy application with some sort of display virtualization layer, if such a thing exists.

What is the most popular resolution in use in your company? Our is 1440 x 900 (15" widescreen).

Is anyone using 1024x768 or less anymore? I'm sure there odd machines here and there but I'd have thought >1024x768 is not popular, am I right?

Finally what's the lowest resolution you have in general use?

Thanks

We've got a workstation with four monitors that is shared by multiple users. Depending on the user, the screen resolution of all four monitors needs to be changed. I'm looking for a way to simplify/automate the process of changing the resolutions, possibily with a script of some sort? Can this be done?
