We're currently developing an application which (just one of the features) shows a interactive map on a videowall.
This videowall has a very high resolution but is constructed out of pretty old displays/tubes. Together these displays form a high resolution; I don't know the resolution exactly, but starting Microsoft Word shows a small window in the upper left corner of the videowall. I will lookup the resolution next week.
There's a debate in our team on whether we should use dark or white
background when displaying texts (say around 200 words).
Not considering the fonts, font size, and color contrast, I found
myself feel more comfortable to read texts on dark background for
longer period time on screen. Some posts I found on web (such as http://my.opera.com/Vorlath/blog/show.dml/283240) also state print
media and computer screen are different. Computer screen itself
outputs lights and thus white background can be blinding.
