13 Big Myths About Tech

By Angela Colley

NEW YORK (MainStreet) —We’ve all heard that more bars mean better service, that a camera needs a lot of megapixels to take good pictures, and that Macs don’t get viruses.

There seem to be as many technology myths as there are people who repeat them. How can you separate fiction from fact?

In the video below, Money Talks News founder Stacy Johnson dispels five of the biggest tech myths that could be wasting your time and costing you money. Check it out, then read on for eight more myths you should know the truth about.
Let’s explore how much truth there is to these widely shared technology beliefs.

1. You need expensive HDMI cables

Many people believe the more expensive the HDMI cable, the better the TV quality. But as we figured out in "Are Expensive HDMI Cables a Rip-off?" cables generally work the same, no matter what you pay. In fact, CNET reviewed cables from brands like Belkin, Monster and Accell and found you shouldn’t spend more than $10 for a 6-foot HDMI cable.

So whether you buy a $50 HDMI Monster cable, which has an average three-star Amazon.com rating from 140 reviews, or you purchase this $7.99 cable from Mediabridge, which has a five-star rating with 5,451 reviews, your TV will look the same.

2. More bars mean better service

If your cell phone has four bars, you should have excellent reception, right? Not always. PCWorld tested the correlation between bars and actual service in major cities and found it doesn’t really make a difference. For example, in San Francisco only 13 percent of tests showed a connection between bars and service.

When your phone has full bars, it actually means you have a good connection to a nearby tower. But if thousands of people are accessing the same tower, or your provider’s backend network isn’t great, you’ll still get dropped calls, fuzzy reception and slow data times.
