Hello,
As a general note, when installing a ceiling projector, can you please insure the contractor:
1 - terminates the cabling at the table
2 – installs 1x VGA and 1x HDMI cables
If you look at the meeting rooms on the IT area on the 7th floor, you will see the projector cable on the table goes directly to the ceiling. So when a plug breaks (conference 3, for example), the only solution is to replace the entire cable. If this were terminated to the table, we would only need to replace the extension patch.
