I have a web page that will run on a multiple TV display, 6 1080p TVs aligned in two rows using those adapters that aggregate multiple displays in a single feed. That means I'm developing for a ~6000x2160 resolution which seems to be the exact opposite of the problem everyone else is having with testing on mobile devices.
The thing is that I actually need to make the browser window at that resolution to properly test my application. I want to get some base idea of how to position and size the elements of my page, so I don't need to see the whole screen at once. I'm wondering if anyone ever encountered this problem before. Before I try to dive on VMs hoping that they support such high resolution I thought to ask about this here.
I know any tests I perform on my conventional monitor will not be accurate because of DPI differences, but it's better than nothing since I can't be on the client all the time.
