Hi Anatoliy,
From memory the browser used on the 4400 is a modified version of Mozilla 1.7.1.3. This has only limited support for CSS2 tags, and no support for CSS3. In our experiences, we've found that if we need specific fonts for design or branding reasons, the best way to achieve this is through the use of images instead.I have to admit, this has been one of our frustrations in designing content - particularly dynamic content - for distribution through the DMPs.
It would be great if future versions of firmware used a more recent - and therefore more compliant with newer web standards - browser..
hope this helps,
Kathy
