Turn Off These 3 TV Features for Better Picture Quality

“Hey,” you might say, “why do I want to turn off noise reduction? I don’t want to see any noise on my TV!” That would seem to make sense, except it doesn’t.

Noise—sometimes called “snow” on account of the black and white dots in the picture—was a big issue decades ago with analog TVs, especially with low-definition analog signals. Today, when TVs upconvert video signals from low-quality sources, you may still see some noise.

But for the most part, you’re getting much cleaner, higher-quality digital source content these days, whether you’re using over-the-air digital broadcasts, high-def signals from cable or satellite TV services, streaming service signals, or pristine video from Blu-ray discs.

The problem with noise reduction is that it comes at the expense of detail and fine texture; these tend to get smoothed over when the feature is active. The picture can get soft-looking. Turn off noise reduction and you’ll have a more natural-looking image.

Another entry in the “sounds good but really isn’t” department is sharpness control, which doesn’t actually make the image sharper.

What it really does is accentuate the edges of images. At first glance, this might give the impression of greater detail, but in reality it masks fine detail—and oversharpened images can add a halo around objects.

So turn it way down or completely off. Some TVs have a zero setting in the center of the control. That’s what you should use. Lower it beyond that point and you might actually soften the image.

One issue with LCD-based TVs in particular is that the image can blur during fast-moving scenes, especially in action movies or sports.

TV manufacturers use various technologies to reduce motion blur, such as repeating frames or inserting black frames into the video signal. These techniques go by a number of names, including Auto Motion Plus (Samsung), Motionflow (Sony), and TruMotion (LG).

So what’s the problem?

On its own, blur reduction is fine, even helpful. But many companies tie these efforts to another technology called judder reduction, which is often referred to as motion smoothing. Movies have a slightly stuttering effect, called judder, especially when the camera pans across a scene. This appearance comes about because movies and a lot of prime-time TV shows are shot at a relatively slow 24 frames per second, or 24 hertz.

By contrast, video is typically shot at 60Hz. That’s why sports, reality and game shows, and soap operas have smoother motion than 24Hz films.

Motion smoothing attempts to reduce judder by increasing the TV’s frame rate in a process called frame or motion interpolation. The TV analyzes adjacent video frames, making an educated guess as to what the in-between frames would look like if they’d been captured, and then inserts those new frames into the video stream.

But when motion smoothing is activated during a movie, it removes the normal film cadence and can make even classic, gritty films look like video, a result referred to as “the soap opera effect.”

Many sets with 120Hz and higher refresh rates let you turn off motion smoothing separately from blur reduction. Do that if you can.

But with some televisions the two effects are tied together, so you can’t get one without the other. In that case, turning the feature off is probably your best bet.

One of the new picture settings I mentioned above, Filmmaker Mode, helps eliminate the soap opera effect. When it’s active, the TV will automatically shut down motion smoothing and some other features when it detects a movie is playing. This year, sets from Hisense, LG, Panasonic, Philips, Samsung, TCL, and Vizio have a Filmmaker Mode setting. A newer development is the use of sensors to detect ambient room light and then adjust the settings for Filmmaker Mode accordingly.

Netflix Calibrated Mode also tries to eliminate the soap opera effect—and adjusts color, brightness, and contrast—but only on the service’s streaming movies and original shows. So far, it’s mainly found in TVs from LG, Panasonic, and Sony. Amazon introduced something called Prime Calibration Mode on some Sony TVs that automatically adjusts the picture settings to match the original mastering of Prime Video content TV.

We’ve found Filmmaker Mode to generally be a useful feature that comes close to our own optimized settings. But you may want to raise the TV’s brightness just a bit because Filmmaker Mode assumes you’ll be watching in a very dark room. (This is the problem that TVs with ambient light sensors are meant to address.) We haven’t tested Netflix Calibrated Mode yet.

As we noted, many newer TVs have a Filmmaker Mode. If your television has this setting, it’s worth turning on to automatically turning off unnecessary processing, including motion smoothing.

In our TV labs, we now start our testing using Filmmaker Mode, when available, because it brings the TV closest to our final optimized settings.

Here are a few great sets that have Filmmaker Mode.
