This year there will be a number of door buster deals at various retailers for the upcoming Black Friday sales.

One of the things you may be considering is upgrading the television.

With so many new models being released, the urge to buy a bigger and better version is probably strong, especially with the stiff discounts being touted in the various advertisements you’ll see in the coming days.

But there are several things you will want to consider before setting your alarm and balancing your checkbook.

These new televisions, called 4K sets, are essentially clearer versions of the flat screen television you currently own, but there’s not a lot of content available in that format just yet.

So, before setting a course for a long wait in line, consider this; does your current set work? If so you may want to continue using it for another year or two while the price of 4K sets continue to drop. Here’s why.

You may have noticed the new videodisk section in the electronics department of your favorite store touting a new 4k format. Take a look at how many titles have been released so far. While the selection is growing, it’s not quite substantial, yet.

There are streaming services touting content in 4K, but there are several aspects to consider on that front as well. First, you will need the television and device capable of streaming such content. Check the website of your streaming service provider for compatible devices. Trust me, the list is short. Netflix in 4K will work on about 10 compatible devices available in the U.S., and they’re all relatively new. That means you probably don’t already own one.

Also, check your Internet connection speed. Do you get a steady 25 MB or more? If not, no matter the television and connected device, you won’t receive a 4K signal from a streaming service.

Lastly, keep in mind that those door buster deals are limited in supply. You could end up standing in line for hours just to find out that all of the items you waited for were already claimed.
