HP8200 displayport to HDMI

[Jobos]

I want to connect the displayport on a HP 8200 to a Promethean Activpanel HDMI port. Can I use a displayport to HDMI cable or do I need to use an active adaptor?

 

Thanks is advance.

I'm not doing it to a promethean panel, I'm just doing it to a big TV, but a short-ish, less than 5m, run seems fine on a passive adapter.
