what is hd readyTelevision manufacturers can be a tricky bunch. Just when you think you’ve figured out their acronyms and slang, things change again. In the early days of HDTV people were scrambling to figure out the difference between 1080i and 1080p and manufacturers were playing sly with acronyms by sticking the EDTV (Enhanced Definition Television) acronym on sets without explaining how it differed from HD.

As the market for HDTVs matured, the manufacturers settled down and organizations began to develop standards, but the terms are still sometimes confusing. “HD Ready” and “Full HD” are short-hand definitions often attached to sets, but the difference between them isn’t always clear to the layman. Read on if you still find the picture to be a bit fuzzy.

HD Ready (In the United States)

what is hd ready

The term HD Ready was used in the United States to note a display that had the ability to display a high-definition picture (720p, 1080i or 1080p) but did not have a built-in HD tuner.

In other words, the display worked like a monitor 3 Things You Can Do With Old Computer Monitors 3 Things You Can Do With Old Computer Monitors Read More . It had to be connected to a set-top box or other high-definition content device that could drive a signal to it. A full HDTV was different because it had a built-in HD tuner that could receive HD over-the-air transmissions.

The term HD Ready became obsolete in the United States due to FCC mandates that forced television manufacturers to include a digital tuner. The mandate went into effect for all televisions sold after March 1st, 2007.

HD Ready (In Europe)

what does hd ready mean

The term HD Ready is different in Europe. In 2005 an industry association known as EICTA (and since re-named DIGITALEUROPE) set down a standard for the term HD Ready. For a television to qualify as HD Ready it needs to be capable of 720 horizontal lines of resolution. It also must accept certain inputs such as HDMI or DVI with copy protection (HDCP).

There’s also a standard called HD Ready 1080p. This standard demands that a television have native resolution of 1920×1080. It also must be able to display 1080p and 1080i video sources without overscan (in other words, the image as displayed is exactly 1920×1080) and must be able to reproduce video formats without distortion.

As in the United States prior to the FFC mandate, an HD Ready television may not include a digital tuner and will require a separate tuner device to function.

An additional HD TV / HD TV 1080p standard has been created by DIGITALEUROPE to represent a television that has a built-in ability to decode HD television signals and display them in compliance with the HD Ready / HD Ready 1080p standard.

This is still a relevant difference because only some European countries have mandated digital tuners in all televisions.

Full HD (Everywhere)

The term Full HD is often used in marketing materials across the globe. It is not, however, a standard that has been adopted by any government agency or trade organization. Full HD is used as a synonym for 1080p as a means of up-selling consumers looking at HD Ready sets.

1080p televisions have a resolution of 1920×1080 and are progressive scan, which means all lines of each frame of video are drawn on the set. This marks 1080p as different 1080 interlaced (1080i) which alternates between rendering only the horizontal and vertical lines of each frame.

Since Full HD is only a marketing term, it does not indicate any particular qualities besides 1080p. A set labeled as Full HD may not be capable of 1-to-1 pixel mapping or might not be able to properly display all 1080p video sources. You’ll need to refer to manufacturer spec sheets and independent reviews to be sure.

Does It Matter?

what is hd ready

Now that you know what the terms mean, we are forced to return to an age old debate. Does 1080p (aka Full HD) matter?

The answer is – it depends. The only thing that can be said about a set with 720p (a.k.a. HD Ready) resolution is that it has fewer pixels than a set that features 1080p (aka Full HD). The terms say nothing about overall image quality, color accuracy, the black levels and concerns that have a significant impact on image quality.

A 720p display may appear less sharp than a 1080p display. The difference will become more noticeable as physical display size increases and the distance between the viewer’s eyes and the set decreases. A viewer with 20/20 vision sitting six feet away from a 51” television will likely see a difference. The same person sitting ten feet away may no longer notice it.

While display resolution does not directly indicate overall image quality it’s worth noting that most manufacturers only sell 720p sets only as budget models. As a result, a 720p set probably won’t have world-beating image quality.

Conclusion

I live in the United States. The information presented here is referenced directly from the DIGITALEUROPE website as well as the U.S. Digital Switchover website.

I do not have knowledge of other parts of the world such as Asia and Africa. If there are standards in your country that don’t agree with what’s listed here, feel free to post them in a comment. I am sure other readers will find them helpful.

    Full HD means the TV has a built-in HD Tuner, and it will display upto 1080p through any input mode.
    HD Ready means that the TV does not have a tuner, and it will need an external tuner to support HD transmission, or it will downscale the image received to 1280x720.

      Yes 1080p is the best, unless you have a higher resolution. (This is how I see it anyway)

      Yes, there is so-called Quad-HD or 2160p. That's in the works right now.

    I only prefer Full HD on certain movies, but besides that I'm fine with 720p or even SD.

    I believe 1080i refers to interlaced display. Interlaced when I was in this business (2002) meant every other horizontal line was drawn. If you numbered the 1080 horizontal lines, first the odd lines were drawn, then the even lines. This can give rise to interference patterns when displaying images in low light or especially foggy or misty pictures. The lines are not drawn at the same time, so they don't quite line up as each line is drawn.

    In Brazil several years ago the government mandated that all TVs had to begin to be manufactured to HD use. Originally the TVs were more like monitors and a converter box was used. Today 95% of all the TVs manufactured have the converter for digital signals installed in the TV.

    Also since cable TV is very popular here in Brazil all of the cable and satellite TV providers have in their own switch boxes the converter, which can detect if the TV has a converter installed or not. If the TV has a converter already installed the cable/satellite box will bypass the TVs system. If the TV is HD ready but does not have the converter installed then the cable/satellite box will use the converter they have in their box

    In Russia, HD Ready means the screen resolution 1366 x 768 or 720p

    • Joses Lemmuela

      not 1280x720?

      • Matt Smith
        July 20, 2012 at 3:53 pm

        Here in the 'States, there are TVs with 1366x768, but they are called 720p to avoid additional confusion.

        • Jon Green
          July 20, 2012 at 10:25 pm

          This is normal in Europe, too. The panels have 1366x768 native resolution, and this available for VGA inputs for instance, but only display 720 lines when displaying broadcast TV.

    The description of 1080i is completely incorrect. With interlaced scan formats (720i, 1080i), even-numbered lines are shown on one scan (or field), odd-numbered ones on the next. This is similar to the old analogue television, where the speed of transmission was halved by sending alternate scan line sets ("fields"), so that if the screen was displaying at 50Hz (Europe), you only got a full picture ("frame") every 25th of a second, not every 50th. The same principle applies here. The result is that fast motion looks a bit of a mess - but it's cheaper to do, both in terms of transmission and in the TV. It has nothing to do with alternating horizontal and vertical scans!

    The progressive-scan formats (720p, 1080p) display ALL lines on EVERY scan. If the scan frequency is 50Hz, as before, you get the whole frame every 50th of a second.

    • Matt Smith
      July 19, 2012 at 9:07 pm

      Ah, yes. Sorry for the mistake. It is an alternate between odd-number and even-number, not horizontal and vertical.
