How can you increase the picture quality on LG smart TV?

Answer 1

The following is a general discussion about optimizing image quality and can apply to LG or any other brand of television. The information assumes that the television is receiving a digital signal from a broadcaster or via the internet.

Picture quality is largely based on the quality of the incoming signal but it is also very subjective. There are many factors that can affect the apparent quality of the image such as brightness, contrast, color saturation, color temperature and more complex factors such as image processing within a television to "enhance" the viewing experience.

As a starting point, make sure that the television is set to its defaults. Typically that will be brightness, contrast, color, hue, sharpness all set to their mid-points. Dynamic image, or contrast controls should be turned off along with any other enhancements. Fast frame rate should be turned to 50 or 60 Hz. From this point, try adjusting one control at a time and assess the image quality. Don't make extreme adjustments. Try using features such as "cinema" mode, dynamic image processing, fast frame rates and compare them to the non-processed signal.

With today's digital broadcasts, there is little to be gained by changing receivers, cables or other equipment in the signal chain. The nature of digital signals is such that if an image is received, it is received at an identical quality as was broadcast. An HDMI cable, for example, either works or it doesn't. Spending a lot of money on expensive HMDI cables to replace one that works will not improve the quality by even the tiniest amount. Don't be fooled by claims from sale people or manufacturers that their HDMI cable will be better than a cheap one. It won't.

Similarly, changing cable receiver boxes, satellite receivers, satellite dishes etc will almost certainly make no difference to the quality.

However, if a television program or video feed is being delivered via an Internet link, the quality will deteriorate with a poor connection. Low incoming data rates or high rates of data errors can cause errors in the image or just a generally poor image as the incoming video drops to a lower data rate to cope with the poor connection. In this case, quality may be improved by avoiding other downloads while streaming video or by increasing the ISP's data rate offered to you.
