ADV7842 VGA input ESD protection?

In the ADV7842 and EVAL-ADV7842-7511P documents I don't see any mention of ESD protection for the VGA inputs. It seems to me that ESD protection on the inputs would be advised. I searched around a bit for recommendations, but what I've been finding availble for VGA specific ESD protection appears to be for host side protecting the source at the output connector, with line driving buffers for the HSYNC and VSYNC lines.

 

Is ESD protection of the Analog inputs, and HSYNC and VSYNC lines really not necessary? What is advised as a best practice for the ADV7842?

 

Thanks for any input people can provide!
