We put the biggest AV technologies against each other in our display cable comparison
AV specs can often seem baffling, with contrast ratios, luminescence measurements and pixel counts all assaulting you with information.
One of the most confusing aspects is the sheer multitude of AV options. With PCs and monitors sporting inputs for HDMI, DVI, VGA and more, how can you know which one to go for?
We’ve squared the two biggest contenders off against one another, to find out once and for all: which is better, HMDI or DVI?
HDMI vs DVI: Layout
The principal difference between HDMI and DVI cables is in layout. DVI is bigger, and features a 24-pin set-up similar to VGA or SCART cables, although some do come with less pins for lower-resolution devices. HDMI is much more compact, and resembles a USB input, measuring about an inch across.
DVI comes in a variety of layouts designed for very specific tasks. It’s now possible to get DVI-D (digital) and DVI-I (both analogue and digital), as well as the less common DVI-A (analogue) versions of the cable. To make things even more confusing, these are also available in single-link or dual-link varieties (which is important for when we come onto refresh rates).
HDMI keeps things a little more simple, with newly released versions of the cable sticking to a numbered system. We are currently on HDMI 2.0, with 2.1 expected mid 2017, bringing support for resolutions up to 8k and higher frame rates.
