Question Simulating Screen Resolutions - Testing Application

Hi All,

Interesting one here.

Have a Winform application which works on all standard screen resolutions. Came across a laptop (new model DELL) which was is a high end model and is able to set to a super high resolution (3840 x 2160), which by default windows sets the zoom/DPi to 250%.
Found this link High DPI support in Windows Forms which helped and have began making adjustments which is allowing the program to work on these types of HD resolutions.

My Question:
Is there a way to simulate/test the application whilst building in dbug mode on my developer PC that will simulate the 3840/x2160 resolution (and other high resolutions). My Current laptops and monitors only go up to (2560x1080). Possibly something like a resolution simulator? I know they are ones for mobile devices, but for high res HD testing?

Currently I have to compile, and then run the app on the DELL user pc to see if the changes/layout worked.


If anyone has any ideas, suggestion or feedback it would be much appreciated.

Thank you
