Perspective View size has to match tablet pixel resolution

The default view size is 800px by 800px on ignition perspective view windows.
I will be using a GETAC ZX10 tablet which has a resolution of 1920 x 1200.

However, I will also have a desktop that has a resolution of 1920 x 1080.

What should I set my ignition perspective view window size to? Does in matter? I will be using flex containers

The Flex Container component is used inside a view.

You need to create a new view and set Root Container Type to Flex Container. This will expand to fill the available space in the browser.

There's more in the manual and the Inductive University links on that page.
