Other options, like Amazon Video on Demand and so on, are either similar to Netflix in quality or fall somewhere in between Netflix and Blu-ray. Compare the detail with what you see in the streaming and DVD images above. A pristine 1080p image, as if sourced from Blu-ray. Most Blu-ray movies offer a pristine and highly detailed image. However, it's not as detailed or as "clear" as a Blu-ray image.Ī third movie-watching option, and the best for picture quality, is Blu-ray. As you can see, compared with the upconverted DVD, there is more detail in the image. Check out What is the blockiness in my TV's picture? for more on these other artifacts. Note that there are other artifacts common with streaming (macroblocking being the most likely) not shown here this image is just an example. Here is the same image, again still 1,920x1,080 pixels, but simulating a compressed 720p streaming image. Generally it's still better than DVD, though. The side effect is a softer, noisier image. Compression is a way to squeeze HD into lower data rates, making them easier to transmit. This is a highly compressed, and likely a 720p (1,280x720-pixel) signal. passive 3D: What's better?Īnother common way to watch an HD movie is streaming the movie via Netflix or a similar service. The lower-resolution source is upconverted to fit your TV. If you're watching a DVD or other standard-definition source on your HDTV, this is what you're seeing. Note the image is 1,920x1,080 pixels, but lacks detail. Detail is hard to see in the small versions of these pictures shown below, so please click on the images to see the full resolution. The first of our example pictures is a 1,920x1,080-pixel image, the resolution of your 1080p HDTV, but sourced from a 480p DVD. For what we're talking about here, it's not important.) (Note: Technically, DVDs are 480i, but as the deinterlacing step is separate from the upconversion, I've left that out. Hence, even the best upconversion can't compete with real HD. The TV makes up pixels to fill its 2.1-million-pixel screen. In this case, DVD video is only about 345,600 pixels. You're seeing 1,920x1,080 pixels (your TV's resolution doesn't change), but the detail is limited by the source. With DVD, your DVD player or TV converts the standard-definition signal to 1080p. Let's take three common ways to watch a movie: DVD, streaming, and Blu-ray. Remember, all three are 1,920x1,080 "Full HD 1080p," but as you can see, their quality is visibly different. I've mocked up some images below to demonstrate what three sources of different quality can look like. Just as an HD TV isn't necessarily showing HD video, just because something is called HD doesn't mean it is actually true HD-quality. Check out this post on how to get free HDTV.ĭVDs, even played in an " upconverting" DVD player, do not show HD video. You can get free HD, if you don't want to pay. For example, channel 2 might be the SD channel, but 1002 is the same channel in HD. Often, the HD channels are separate from the SD channels. Even if you receive HD channels, you may need to select specific HD channels. Remember, just because you see an image, this doesn't mean it's HD. Or, you may need a new cable/satellite box. Sometimes this is as simple as calling them to activate the HD channels. Nearly all cable and satellite providers require you to enable HD signals. They're the best thing you can do for your TV, if you haven't already. HDMI cables are cheap you can get them for less than $5. If you're unsure of what connects where, check out this guide to how to set up an HDTV. Even the Wii looks a little better with component cables instead of the yellow composite cable. If you're using a yellow cable for anything other than a Wii or a VCR, you're shortchanging your TV. It is not a yellow cable with white and red cables: that's a composite cable. Component cables consist of red, green, and blue cables, plus two more for audio. Only HDMI and component cables can transmit HD. Make sure you're getting the most from your TV with this guide.īefore anything else, make sure your HDTV is actually receiving HD signals. A variety of factors could be conspiring to create an image that's not nearly as good as what your TV is capable of. For that matter, just because you have an HDTV, that doesn't mean you're actually watching high-definition video.
