An HDMI port is by far the most popular display connecter by far, but it's not perfect, and here's why.
Some of you will remember those times where, if we wanted to connect a device to a TV – such as a gaming console, VHS or early DVD player – we'd connect the RCA cables (Radio Corporation of America) to the TV and, essentially, hope for the best.
The TV would then simply display the inputs it would get from the device and showcase the resolution, frame rates and audio.
However, more modern alternatives, such as HDMI and Display Port cables, do this all digitally with the help of a system called: EDID (Extended Display Identifications DATA). EDID is a system from the device that essentially finds out exactly which resolution, refresh rate and colour profile is optimal for the display you are connecting it to, and thus transmits the optimal settings. Well, at least that's what it's supposed to do!
In perfect situations that is exactly how it works. However, issues arise when you put something in between the display and the device, such as a receiver. If you prefer to run your audio through a receiver, the EDID data now has to run through three devices and not just two. In the best-case scenario, you're most likely going to experience a minor delay when operating your device. In a worst-case scenario, the EDID data may become lost or corrupt and you'll not be able to see or hear any audio or visuals.
