I assume by "display" you need your internet browser.
This is to do with the security settings in your browser like "Trusted",
"Internet", "IntraNet Zone", "Restricted" You can list whichever sites you
visit in these zones, so something like "trusted" would be those sites you
trust not to deliver damaging content; or "Restricted" would be sites that
could cause harm or contain damaging content. The "internet" zone would be
for sites that aren't in the trusted or restricted category.
So in IE this is under Tools, Options, Security.
