If you are having problems adjusting the size of the picture on your TV, the problem may be the cable box. If you have AT&T U-verse cable service, it’s almost definitely the cable box. I’ve run across several examples in recent days of the picture being either too big or not big enough. Most people automatically blame the television, especially when they check the settings on their cable box and everything looks correct. However, looks can be deceiving.
Here are some tips to try and correct the problem for bars on the sides of the picture. First, eliminate the TV as the culprit by checking your settings for picture size. Make sure the television is set the way you want it. If you don’t like having the bars on the sides of your picture make sure it is set for either “full” or “wide” (every TV uses different terminology, it may even refer to “aspect ratio”). Try rebooting the AT&T U-verse box, by unplugging the box for a minute. If that doesn’t fix it move on to the next step. Next check the set up on your AT&T U-verse box. On the U-verse remote hit menu and arrow over to options, you are looking for “aspect ratio” in the sub-menu. There will be four options there (4:3, Wide standard, 720p and 1080i).
Ok, here’s where it starts to get a little weird. If the box is set for wide (which it should be if you don’t have high definition service) change it to 4:3. I fixed two problems doing this. It is completely backward, but it works!
For problems where the picture is too big, again check your Television and U-verse settings to make sure they are not in stretch or zoom modes. Sometimes the combination of settings can cause this. Once confirmed that everything is ok, you can try rebooting the U-verse again. If that doesn’t repair it, go into the U-verse menu and find “aspect ratio” as in the previous example. With this problem I have found that selecting the same setting it’s already on and allowing it to test this mode will correct the picture size.
Now of course the obvious question is why is this happening in the first place? Good question. I have no idea, but I would assume some sort of software glitch. That is a question to hit AT&T with. There is also the possibility that this problem will re-occur and that service from U-verse will be needed.
