Actually, totally the other way around.The small buttons look terrible on my setup, i guess the designers at inno all have huge clear monitors.
Im on 1366x768 and it looks absolutely perfect, everything is just the right size.
I believe it has been optimised for 1024x displays so if you have a smaller monitor at 1024x it will look just dandy (allegedly)
On a big monitor im figuring it will be awful. Looking at the css most of the text sizes are fixed at around 10px to 12px, which on a 1024 monitor is pretty much perfect, on a large display 10px is far too small to the point of being unreadable.
So I would say that Inno have tested on 1024x786 and 1366x768 and NOT tested on larger monitors.
This is the problem with the web now, for years we tailored sites to work at 800x600, then we optimised them for 1024, then gradually we started optimising them for 1280 and higher. NOw with so many people using tablets and mobile devices theres almost been a reverse, and once more 1024 is back in fashion. Of course the answer is proportional and responsive websites, with elements adjusting themselves to the size of your screen, but then, isnt that what the zoom button in your browser is for
This is why its common now for websites to have huge blocky fonts, and massive blocks of colour. Keeps the large monitor guys happy whilst also looking great on tablet.
