While the easiest way to connect a Mac to a projector is with a cable, it can get more complicated in a fast-growing company where you don’t have standardized notebooks. Nearly all the new projectors have HDMI ports, but if you have an older projector with a VGA port, it is going to be a challenge to connect it to your new 27” iMac with the Retina screen your programmer is asking for.
Apple has also been changing its ports on their notebooks, going from VGA, to HDMI, to mini-DisplayPort, and now Thunderbolt 3 using USB-C. So which cable do you put on the table to enable everyone to connect?
If you have an HDMI equipped projector, you can use simple adapters on the cable to convert the HDMI signal to the right physical form to connect to your laptop. The projector won’t know the difference – and all the HDCP copy protection and image quality enhancements such as resolution scaling will work to make any Mac look good on the screen. Apple has a helpful guide on their website.
The other thing to consider is that if you want your conference room table to have a clean and organized look (just like your Mac), hiding and managing cables can be expensive forcing you to spend precious capital to hire carpenters to cut holes into tables and electricians to run cables through walls and ceilings. Of course, if you outgrow your space and need to move – its wasted money.
