Just a low-effort initial observation: "Works in IE8+, FF, Chrome" but the demo depicts an iMac display :-)

EDIT: Seems to work fine in Safari too!

iMacs can run FF and Chrome natively, and I've encountered a number of folks running Windows or Linux on them as they like the Apple hardware. Not sure what your point is...

Even lower-effort initial observation: I have to scroll horizontally to see the whole page with my portrait-orientation display.

I wanted to run 3x portrait so bad until I realized that side scrolling would have to become a fact of life for me to do so.

I got a chance to do this when an office reorg temporarily granted me a third monitor. The occasional horizontal scroll was more than compensated for by the feeling of godlike power.

3x portrait 1x landscape has driven me mad with power. They're 4k, so I don't actually have to scroll here. Only downside is having to buy my own monitors for work because I've spoiled myself.

10/10 would sell my soul for more pixels again.
