Auto Refresh Dashboards and Reports

I'm trying to accomplish a similar thing. I have several chromeboxes displaying dashboards on TV's throughout our building. I'm using the Super Auto Refresh extension to refresh the page every 5 minutes, but as far as I can tell the only way to get it to refresh properly is to use the "Refresh Dashboard Tiles" menu option or clicking through to the report. Refreshing the page alone does not seem to update the dashboard tiles.

After reading some articles it seems to me like Dashboards weren't really meant to be used for this type of "live" digital signage application. I believe that's why they allow developers to embed dashboards and tiles into applications. Problem is, I'm not a developer and this seems like an obvious use case for regular dashboards.
