I have been searching this over the web for 2 days now and I am still unable to get my hands on something helpful. I have to run my windows 8.1 app on large device (i-e 80 inches) having 4k(3840 X 2160) resolution. The max resolution I have on the windows simulator is 2560 x 1440 (i-e 27 inches). Is there any way that I can add custom screen size/resolution to windows simulator? or is there any other option available where I can test my app on 4k resolution?
PS: I don't have a 4k device with me right now, that's why I want to test it on some simulator.
Thanks in anticipation.
The simulator doesn't support custom resolutions.
If you design your UI to be flexible and test it at a variety of resolutions and DPI levels you should be able to get a pretty good idea of how it will work. Running at 1920x1080 will give the same ratio as 3840x2160, just scaled by half in each direction.
