Here's a fun geeked out comparison for you today; DVI and HDMI. Sure, we all know they carry digital signals and do HD, but which comes out on top when given the option to send signal to the TV via a HTPC or your laptop?
We do a pixel to pixel comparison as well as answer a few common questions regarding the two formats, after the jump.
From How-To Geek:
DVI is one of the most common digital video cables you'll see on desktops and LCD monitors today. It's the most similar to VGA connectors, with up to 24 pins and support for analog as well as digital video.
DVI can stream up to 1920×1200 HD video, or with dual-link DVI connectors you can support up to 2560×1600 pixels. Some DVI cables or ports may include fewer pins if they are designed for lower resolution devices, so you'll need to watch for this. If your port contains all the pins, however, it can support the max resolution with no problem.
The biggest problem with DVI is that it doesn't support HDCP encryption by default, so if your hardware only includes DVI ports, you may not be able to playback full HD Blu-rays and other HD content.
On the other hand, for HDMI...
HDMI is the default cable on newer HDTVs, Blu-ray players, Apple TV, many new computers and video cards, and a multitude of other video devices. HDMI cables and ports are very easy to use, and are almost as easy to connect as USB devices. No more bent pins; just push and play. HDMI cables can stream digital video and audio simultaneously over the same cable.
HDMI cables support up to 1920×1200 HD video and 8 channel audio. They also support HDCP encryption for the newest HD content. For almost all purposes, a single HDMI cable is all you'll need to connect your computer or video device to your monitor or TV, and it's almost the absolute standard digital cable.
While both pretty much carry the same resolution, we like HDMI for its sturdiness and ability to send both HD video and audio. We've had mixed feelings about everyone's craziness towards the other standard that's up and coming - Displayport (with little to no adoption by TV and monitor manufacturers) and VGA, while substantially worse on LCDs than all of the above (for CRTs it's conversely true), still seems to be the cable of choice for people looking to maximize the number of devices they want to connect to (just have a look at schools, meeting rooms, projectors, etc...).
What about you guys? Do you have a favorite cable as of the moment? Let us know in the comments!
