Back when I taught computer repair we got all kinds of old computers and monitors donated to our classroom. One of the seemingly never-ending challenges was matching monitors with computers. That was particularly true when my students would be confronted by units that had only VGA or DVI inputs. And there was always an conversation that included phrases like “this monitor is so old” and “can this monitor work with this input?” All that to say, I ended up spending time at the start of the course explaining various monitors and connections. I wish I had had Monitors Explained by PowerCert Videos back then. 

Monitors Explained by PowerCert Videos provides an excellent overview of monitor types, panel types, refresh rates, contrast ratios, and response time. 

Applications for Education

This video is obviously helpful for students who are in some type of computer repair class. It’s also good to watch from the perspective of becoming an informed consumer before purchasing your next computer monitor.
