How to change Azure VM (Windows) resolution

BinLIN12 1

we are using Azure VM with Windows to run our E2E UI tests.

The problem is: if we are not connected to the machine with RDP the tests always failed, because the screen of the application (exe) is not matching the resolution of Azure VM.

The VM screen resolution is 1024 x 768, we need to adjust it.. can this be done?

You can handle this by modifying the registry. Update XResolution and YResolution in the hexadecimal units.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Video\GUID\0000\DefaultSettings.XResolution HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Video\GUID\0000\DefaultSettings.YResolution

Note: GUID will be some randomly generated GUID.

Hope this helps

GUID - means - Globally Unique Identifier. All the folders inside Video are {GUID} format. expand them and see whether you can locate XREsolution and YResolution.

all resolution values from 1024 and 768 I changed to 1920 and 1080 also under 00 key above. I also took Stride value from my PC for 1920x1080 resolution and restarted vm.

Please do not forget backup your registry before the changes.

Hey, can you specify which value did you change under the 00 ? I do not see any GUID options (see the image I uploaded)

Under Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\SIMULATED_8086_5917_00000000_00020000_40F04^256252C34736A5EB1E126DA943469A12\00\00

I modified:

I go leve up Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\SIMULATED_8086_5917_00000000_00020000_40F04^256252C34736A5EB1E126DA943469A12\00 and modified:

Stride Value I took from my PC where i had the same resolution so you could do the same for your screen resolution.
