Why does lcd tv look blurry

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. Use the Right arrow button on your remote to increase the sharpness.

Press the Exit button to exit. Note 1: If your cable box doesn't have Component, DVI, or HDMI connections, contact your cable company to see if they have replacement boxes with these kinds of connections built in. I have Hisense H32V77C flat screen tv which is plugged in and little red li TV screen turns mostly white. White screen on lg flat screen TV. I have a Magnavox flat screen tv and the red light to show that the tv is o Red green blue ect. I always notice it when there's a closeup of a face, and then the person turns away.

One second you're seeing every eyelash and wrinkle, the next it's a blurry mess. Some of this can be attributed to the lower frame rate of movies and most TV shows, which can result in a blur caused by the camera. There's nothing you can do about that. There's also blur caused by the TV itself, which, to an extent, you -- actually, your TV -- can do something about. A still photo edited to mimic motion blur.

Note how the lower 1. In the early days of flat TVs and displays, the culprit was often the slow speed of the liquid crystal elements that create an image on LCD TV. These days most LCDs are able to change their states fast enough that motion blur is caused by something else: " sample and hold. With most TVs this means that for a full one-sixtieth of a second, the image is stationary on screen. Then the screen refreshes and a new image is held there for another one-sixtieth of a second.

Some TVs have faster refresh rates, and in some countries TV refresh every one-fiftieth of a second, but the process is the same. Sixty still images every second is fast enough to exceed your brain's flicker fusion threshold. You don't see still images, you see fluid motion.

However, your brain is working fast enough that it's expecting to see motion during those hold times. The images are held long enough that your brain assumes anything in motion is going to continue being in motion… but it isn't. It's actually stationary and then jumps to the next position, which is also stationary. Your brain and eyes, expecting smooth motion, blur the object by moving to follow where it should be.

The physiological reasons behind this are beyond the scope of this article, but the key aspect is that motion blur is in your head isn't everything? Today's TVs have a number of solutions for reducing motion blur, none of which is quite satisfactory.

But your mileage may vary. Here are the pros and cons of four potential motion blur solutions. TV manufacturers have known about the motion blur issue for years.

It's the main reason for higher refresh rates. Modern 4K TVs max out at Hz , but in the p days , there were models up to Hz or and Hz, depending what country you live in. Higher refresh rates don't, in and of themselves, fix the motion blur problem. The images are still being held, and if you just double the number of still images to fit 60 into you haven't really changed anything. You need something to change to , and that's when things get interesting. The processing in modern TVs can determine, with a surprising amount of accuracy, what happens in between two frames of video.

For instance, if a ball is on the left side of the screen in frame A, and the right side of the screen in frame B, the TV could safely assume that if there was a frame between A and B, the ball would be in the center of the screen. This means there are more frames to switch between, and less time "held" on each frame. This is called frame or motion interpolation. With video content like sports, a new frame is inserted between every original frame, and the result is less motion blur and greater apparent detail.

With movies and scripted TV shows, however, there's a problem. Nearly every movie and nonreality TV show is recorded at a frame rate of 24 frames per second. This goes back to when nearly everything was shot on film. 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.
