DVI? HDMI? VGA? What does it all mean and why should I care?

DVI, HDMI, VGA differences.DVI, HDMI and VGA are three types of connectors that can be used for various electronic appliances. Each type of connection comes with its own pros and cons, and in some cases the best cable to use for your device is something other than what came with it when it was purchased. Here, we explain each of these three and their uses.

For your television, the HDMI connector is the most common. All newer TVs and most computer monitors have HDMI ports and connectors. The cables are affordable, easy to use and include audio. If you’re considering connecting your TV to a computer, your first choice should be the HDMI connector.

HDMI isn’t without limitations, however and isn’t always the most optional choice. Likely, your TV has HDMI 1.4 connections. The maximum pixel resolution at the typical 30 frames per second (fps) is 3820 x 2160. If you own one of the new 4000 pixel resolution monitors, an HDMI limits you to 30fps. In order to get the maximum viewing experience for watching Ultra HD 4K (the technology that is the latest standard in the television industry), you’ll need to purchase an HDMI 2.0 connection, and likely an upgraded TV, if your set is still only compatible with HDMI 1.4 connections.

Similar to HDMI, with DVI, the maximum resolution potential depends on your equipment. The maximum resolution potential depends on the equipment, though. Some cables and hardware (called single-link) can only do 1,920x1,200, while others (dual-link) can do more.
DVI generally doesn't do audio (it varies). So if you're using a TV, use HDMI. Since computer monitors don't usually have speakers, this isn't an issue.

The old-school VGA connector is a cable of last resort. It's not too common anymore, and hardly ever found on TVs. Don't use VGA, not if you can help it. While it is capable of fairly high resolutions and frame rates, it's an analog signal. You're not likely to get a pixel-perfect image with today's LCD monitors (hence why you'd use DVI).

They did a great job in setting up my new laptop. They loaded new software and they moved over all my data and programs from a 12-year-old desktop. I'm thrilled with the new, faster computer and having all my old systems still working!!

I had a hard drive go down on a piece of video equipment. Michael and Computer Corner had me up and running in just a few days (parts had to be ordered). Thank you Computer Corner!

My son owns a computer businness in NC so when we needed someone local, we got a recommendation for Computer Corner from a friend. I am more than pleased. I will recommend them in a heartbeat. They communicated the status of my computer to me by text and the work was done very fast and the turnaround would probably have been faster if it hadn't been Thanksgiving week.

Best experience I've had with laptop repairs in Florida. Answered my many questions quickly, informed me of all of my options, and made sure I took home a well tuned machine. All repairs are costly no matter where you go, but at least you get what you pay for with the helpful staff here. As I type this, I'm planning another trip to see them.
