Summarize the following:
When watching TV in HD, you should notice a significant improvement in color, clarity, and detail. Try flipping between SD and HD channels or sources and see if you can tell the difference. If the image doesn’t look pristine compared to SD, then you are likely not watching in HD.  Live studio broadcasts and sporting events in HD are excellent sources to compare to SD channels. Facial hair, individual blades of grass in golf or baseball, and other images that appear to be 3-dimensional or photo quality are typical examples of HD images. SD images by comparison could be described as a little blurry or fuzzy. Resolution is marked by a number, which tells you how many horizontal lines your screen can hold, followed by the letter “p” or “i.” SD TVs have a resolution of 480i, while HDTVs support resolutions of 480p, 720i, 720p, 1080i, and 1080p. Make sure to choose the highest setting for the best picture quality.  You can find the resolution setting in your TV settings menu. The resolution listing should be in your owner’s manual.  The “i” stands for “interlaced,” which means the image on your screen flickers between every other line, and the “p” stands for “progressive,” which means the image constantly uses every line on the TV screen to display the image. If you have an HDTV and you notice these visual issues, your aspect ratio setting is probably off. Go to your TV or source device setup menu and look for a setting for “crop,” “zoom,” “stretch,” or “aspect ratio.”  Set your HDTV to a 16:9 aspect ratio to get rid of the problem. HD and SD screens have different aspect ratios, so HDTVs sometimes distort an SD image to make it fit the screen. SD screens normally use the 4:3 aspect ratio, while HD screens normally have a 16:9 aspect ratio.

summary: Look for a noticeable improvement in image quality. Check your TV’s display resolution settings. Watch for black or gray bars, cropping, or image stretching.
