Why is my hdtv not clear




















Sign In. What is pixelation? Can't view the video? View it on YouTube. Detach the power cable from the back of the unit, and from the wall outlet or power bar.

Wait 30 seconds and then reconnect the power cable to the unit and the power source. Wait up to 2 minutes for the TV box to reboot. Power on your TV box and test it again. Reseat the coaxial connections Reseating adjusts how the coaxial cable is connected to the device and wall outlet. Detach the power cable from your TV box.

Unscrew the coaxial cable connection from the back of the TV box. The standard cable channels or standard over-the-air OTA channels often appear fuzzy or blurry on your LCD TV because of a mismatch between the resolution capability of your TV and the resolution of the analog signal transmitted by your cable company or OTA broadcaster.

The signal you are getting from your cable company is a low definition i signal, with a resolution of approximately by It is this mismatch between the standard cable or OTA signal resolution and the TV resolution that causes the problem. Note: In many cases, even when you are viewing digital channels, the picture will look fuzzy.

This happens because the signal your set is receiving, although digital, is a digitized standard i or p transmission, not a digital high definition transmission. Again, you have the mismatch between a standard resolution picture and your high definition TV display. On the left, what the teahouse should look like. On the right, when the brightness control is set too low. Notice how the shadows disappear completely.

On most TVs, the brightness control doesn't actually control the TV's "brightness. Like with contrast, there's a fine line between too high and too low. In this case, too high and the image will appear washed out. Too low and all shadows will disappear into black. A closeup from the image above.

Notice how you can't see anything in the shadows in the image on the right. To set brightness, you're looking for the opposite type of content from contrast.

Dark movies, like Aliens or The Dark Knight, are perfect for this. Some famously dark TV episodes might be too dark to use for this. Turn the Brightness control down until everything disappears into blackness or something close.

From there, turn it back up so you can see detail in everything, but the image doesn't look washed out. Another test for this is a darker scene with someone with long hair. The underside of their hair I don't know what people with hair call it away from the light can be a good place to spot shadow detail -- also dark coats at night. Again, you might need to try a few different shows or movies to get it right.

On the left, the original image of the walls of Tallinn. On the right, what it could look like if you set the sharpness control too high. Believe it or not, the sharpness control doesn't really improve sharpness. In a way it improves apparent sharpness, but at the expense of actual fine detail and usually with additional noise.

On nearly all TVs the sharpness control adds "edge enhancement," artificially accentuating any edges the TV finds in the image. The problem is, doing this hides the actual detail in the image, so the result looks more artificial with less actual detail.

A close-up of the example above. Note the extra noise and artificial "halo" around the spires on the right.

So it may seem counterintuitive, but you should turn the sharpness control down, way down. Some TVs look best with the control at 0. If you're used to how your TV looks with the sharpness control way up, as it typically is in the Dynamic or Vivid modes, it might appear soft at first when you turn it down. Find some high-quality 4K content and you might be surprised how detailed it now looks.

You should be able to find the sweet spot on your TV looking closely for textures in clothing, wrinkles in faces, hair and beards, that kind of thing. Although resolution mismatches that cause blurry images on an LCD TV cannot be fixed, you can try a few things to minimize their impact. Most TVs allow you to do this by interfacing with the picture-settings menu, which is different on the various brands of TVs that are on the market. If the blurry images on your TV are coming from an external device, make sure the device is connected with a component or high-definition multimedia interface cable.
