When I connect to my Windows Server 2012R2 Azure VM via RDP, I have resolution 1600×900, 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 1024×768.
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.

ResSwitch is a utlity that will do what you want. Its a command line tool that you send the resolution, colour depth and refresh rate - e.g
resswitch.exe 800 600 32 60
You can use the device switch to specify which device the command applies to, specifying the name of the device. So for 4 monitors you'd probably be best creating a batch file with 4 commands in.
To get the names of the devices you can use ResCopy, also included in that zip file to display them.
How are they connecting? If they are using RDP, then the server's console resolution has no bearing on the remote resolution at all. If the troublesome user is using RDP, then look at the RDP settings from her machine.
If you're not using RDP, then you should update your question to reflect that.

As far as I could find, there is no way to set the default resolution higher than 1024 x 768. So we added a few blocks in the build definition to setup a RDP connection to do the trick. See this post/answer
