Turn on Blue Light Filter on LG TV & Fix Blue Tint

Smartphones, computers, digital monitors, and televisions are the biggest man-made sources that emit blue light. The blue light filter has become a basic feature on smartphones these days. Considering its negative impact on human eyes, this feature has now been making its way to smart TVs as well. By enabling the blue light filter or Eye Comfort Mode on your LG Smart TV and reducing the blue tint, you can save yourself from digital eye strain.

We spend a major part of our days gazing at the screens of our smartphones, computers, and TVs. In doing so, we expose our eyes to the harmful blue light that causes macular degeneration and might lead to permanent vision loss.

Blue light doesn’t affect our eyesight only, it may also have a negative impact on our sleep. It suppresses the production of the Melatonin hormone that regulates the sleep-wake cycle. Too much exposure to the blue light might cause sleeplessness by discouraging the release of this sleep-inducing hormone.

The blue light filter feature is found on almost all smartphones but when it comes to smart TVs, it may not be available. For instance, I have a 2019 Samsung QLED TV but it doesn’t have an option to enable the blue light filter. However, I still managed to turn on the blue light filter on my Samsung TV using the picture settings.

As for LG smart TVs, they have an OEM-branded version of the blue light filter feature and it’s called Eye Comfort Mode. Whether you own a full HD 4K (UHD) or 8K smart TV with LED, OLED, or Nano Cell display, you can put a check on the harmful blue light emission by switching to the Eye Comfort Mode on your LG TV.

LG TV Blue Tint on Screen

I read hundreds of LG TV owners complaining about blue tint in the corner and all over the screen. This problem is found especially on LG LED TVs released before 2019. If you are having a blueish purple tint on your LG TV as shown below, it means it has a faulty backlight LED array.

This problem is common on some LG, Sony, Philips, Hisense, and Vizio TV models that use V17 ART3 LED strips.

LG and some other OEMs use the LED strips manufactured by a company named Vestel. Because of their bad quality, the strips made by this company tend to turn blue with time, or their yellow layer gets damaged.
