Hdtv what do you need

As a result, a projector may not be for everyone. You'll also need plenty of room -- really, dedicated space -- with very little or no ambient light.

The price of HDTVs, like all technologies eventually, has come down considerably since their introduction. Yet even now, you'll still see a noticeable price difference when you hit your local electronics store. Why, you may ask? It comes down to picture quality and set reliability.

In addition, some brands have a solid reputation as being manufacturers of sharp and vivid displays, but you're going to pay more for brand recognition. The most recent mainstream breakthrough in high-definition technology is sets that feature a hertz refresh rate , which is twice the rate of a standard interlaced television. Movie fans, take note: An interlaced TV with the standard hertz refresh rate refreshes one-half of the screen 30 times per second and the other half 30 times per second, for a total of 60 times.

Since movies are filmed at 24 frames per second, and the TV is refreshing 60 times per second, the difference in the frame rate and refresh rate can cause movies shot on film to appear jerky.

To mitigate this problem, TV manufacturers use a technology called pull-down, which brings the refresh rate and the frame rate into alignment. TVs that use a hertz refresh rate -- or even the new state-of-the-art hertz refresh rate -- not only refresh more often, but 24 frames per second of film divides evenly into the refresh rate, and the image appears more smooth on your screen without having to use pull-down.

If you watch a lot of movies, it's probably worth the extra cash to get a TV with at least a hertz refresh rate. Before you head out to go HDTV shopping, it's a good idea to take some measurements of the room in which you'll be viewing it.

First, measure the entire room size and write down the overall dimensions. This information will help you choose the size of your HDTV and any other components, such as speakers , that you may decide to purchase to go with the home theater system. Next, determine where you plan to place the television and measure that area. If you're going to place your new HDTV in a cabinet, take that into account, too. Finally, determine exactly where you plan to view the television from. Measure the area to the central seating position -- with the sofa or chairs perpendicular to the set.

It's this measurement you will most likely use to choose your new HDTV. Generally speaking, the closer you get to most television sets, the more the picture appears to deteriorate. The human eye picks up imperfections when you're up close. Set up the source resolution to match your TV Here's where a lot of even experienced HD owners not to mention cable box installers get confused.

HD sources can have a lot of settings, and to take full advantage you'll want to match the resolution of the source as closely as possible to the capabilities of your TV.

If you have a p TV--the most common resolution among new models--you should set the source to i or, if available, p resolution. If you have a p or x TV, set the source to p resolution. If the source lets you choose among other resolutions, check off every one that the TV can support. If there's a "native" option available, we recommend most users check that one off as well. These steps allow the TV to perform the video processing, and usually TVs do a better job of it than cable or satellite boxes.

Computers should be set to output the native resolution of the display, as long as the TV can accept it. Check your manual if you're not sure what source resolutions your TV can support. Adjust screen format aspect ratio Now that you're watching HDTV, you might notice that the screen often isn't completely full. That's because the wide format of the screen doesn't always perfectly fit the source. The first step is to make sure your source is set to the wide-screen or format mode.

The next is to adjust the aspect ratio control, which can zoom, crop, stretch or properly display the image. The confusing part, aside from the name "aspect ratio," is that such controls can be found on both the TV and the source. In that case you are actually watching the film or show in the format it was supposed to be watched. The best way to do it is leave your TV on auto aspect or normal to watch it the way it was meant to be watched.

When you tune to a HD channel your picture, if the TV is set to auto aspect or normal, will naturally fill the entire screen according to what the content was filmed in.

Keep in mind that some of the local networks HD channels will not fill the entire screen during the day on normal shows. If the show is filmed in HD format and you are on an HD channel it should fill the entire screen. This is normal since the box is having to change formats and tell the tv to also change formats. This is normal. This is a problem easily fixed by you with the remote. First on the remote you need to press menu, then select the Home icon and hit OK.

Next scroll down to setup may have to scroll all the way down off the page to find it and click OK. Highlight Audio Setup and press OK. Are you the last person in the world to upgrade from a standard-definition TV to a high-def set? Well then, congratulations on your patience and your new TV! But we live in an age of wonder and delight.

Did you really luck out and get a 4K set? Well, you actually have a growing number of options for content there, too.
