1080p 1080i what’s the dif?

pioneer-elite-kuro-signature-hdtvHave you or a friend recently purchased the latest, top of the line television?  Is the TV supposed to have the clearest resolution available at 1080p?  But is doesn’t?  So, you might be asking yourself:  If I bought a 1080p television, why is the resolution only 1080i or lower?

First of all, most cable and HD Satellite broadcasters only operate in 1080i or 720p.  The television may be capable of a 1080p resolution picture for your stellar home theater design, but it can only display one that is broadcast in that same resolution.  If the picture is 720p, that is what will be seen on the screen, but remember that a 1080p is also capable of fully resolving any picture less that 1080p.  A 720p television will have to scale down the resolution of the picture to meet its native resolution.  Although right now, broadcasters are full of networks operating in 1080i/720p, it is rumored that satellite providers may be offering a full line up of 1080p channels.

Secondly, if your DVD player or other input is not 1080p “quality,” then again, the television will scale down the resolution to that of the lower-resolution device.  Recommended player include Blu-Ray, X-Box, Playstation 3, or an HD DVD player.  These devices are capable of playing a DVD that is originally written in 1080p resolution.

Getting the best picture on your HDTV

Have you purchased a new HDTV only to get it home and be disappointed by the quality of the picture? Is it just not quite as crisp, clear, and vibrant as it was at first sight? Is the surround sound puny compared to the boom you felt at the store? If your electronics salesperson did not explain the importance of HD feed alongside the purchase of an HD television, Advanced Technology Services is here now to repair the damage. HDTV and an HD feed go together like bread and butter. You can’t have one without the other and be satisfied.

These six “need-to-knows” will provide answers your problem:

1. An HDTV set requires an HD feed

You won’t get an HD picture on your new set unless you contact your provider for a set-top box and/or a satellite dish upgrade. Be sure to ask about HD-specific plans and the offering of HD channels. If you use an over-the-air antenna, a high-def tuner box may be a necessary purchase.

2. SD is still common for most programs

Most major broadcast networks display news and a prime-time show in HD, but the majority of other programming is still broadcast in standard-def. The SD signal is not able to be converted to HD signal for an HDTV, so these programs must be watched in their original format. Many programs are broadcast secondarily in HD on a different channel from the original. These channels will be found further down the list in the triple digits.

3. An HDTV will display an SD signal with poor quality

Be prepared: The HDTV screen multiplies the low-quality of the SD signal in the same way a low-megapixel picture distorts when you zoom in on it. The small screen size of your old tv hid these imperfections, but your larger-than-life flat screen is meant for bigger and better things.

4. SD screen size is not wide screen like HD

That short and stout picture you can’t get rid of comes from an SD screen size (4:3) that is being stretched to fit an HDTV with a 16:9 ratio. This can be easily fixed by adding sidebars to the SD channels through the settings menu.

5. Proper configuration is essential for HDTV, cables, and set-top box

Even if you have an HDTV and HD feed, incorrect wiring set-up can prevent the HD signal from being viewed as it should be. One of the following 3 inputs must be used: DVI input, HDMI input, or the component video input (RCA type – which is often red/blue/green). Check your television’s display and output settings as well to insure that 720p, 1080p, or 1080i is selected, whichever is correspondent to your HDTV’s resolution.

6. Standard DVDs are not converted to HD by an upconverting DVD player

Upconverting DVD players do not change SD signal into HD, they simply adjust the screen size to 1080i or 1080p. The quality of the picture will not improve just because it is viewed on an HDTV. If the original source is SD, you will be viewing an SD picture. Blu-ray and HD DVD players are the only DVD players that produce a true HD signal.

If you are still shopping for an HDTV, these manufacturers are all producers of high-end sets that will tickle your fancy:
