I have configured and use custom fonts (Arial & Lucida Console, both TTF) and the presentation simply renders web page from an intranet site.
I have found that "em" and "%" scaling for font-size css do not scale the same PC (chrome) vs. BrightSign (chromium). The scaling on the BrightSign render is much larger. "pt" does seem to be very close, within a pixel.
Is this intentional, a chromium bug or something with BrightSign? It would be nice to have it fixed so that web pages using scaling will look the same. For now I'm locked into designing with hard-set point sizes.
