What is clouding, banding and flashlighting?
It’s the inability of a display to display a perfect black image.
All types of this inability are due to the construction of LED-TVs, because most of them are using a technique called “Edge LED”, which refers to the positioning of the backlight LEDs.
Some manufacturers are facing this problem by building TVs with less LEDs in the edges, but this causes another problem: the edges are darker than other parts of the image.
Are there TVs without these problems?
Only Full-Backlight-LED TVs or OLEDs don’t have a problem with clouding, banding or flashlighting.
That’s because Full-Backlight-LED TVs are using “local-dimming”, so they can darken various areas depending on the displayed image.
OLED TVs don’t use LED backlight at all.
All pixels are lit by them selves, what means that if the TV tries to display a black image, it simply turns off the pixels that should display the black parts.
Where does clouding, banding and flashlighting come from?
In the most sold type of TVs the problems come from tensions in the panel.
You can simulate this by gently pressing on the panel with your finger.
You’ll see an effect very similar.
What can we do against clouding, banding and flashlighting?
There are several different things you can do against clouding:
1. Loosen the screws on the back of your TV!
Loosened screws helps the panel to relax and remove the tensions.
2. Turn up the heater!
After loosening the screws, your panel is now ready to expand.
Turn your heaters to the max for about one hour and after one hour open all windows.
Now your panel should be in the perfect position.
3. Massage your panel!
What’s better against tensions than a massage?
Grab a microfiber cloth and massage the affected locations with light pressure for about 10 minutes each.
4. Be patient!
After following all steps, your TV needs time.
Most of the clouding, banding and flashlighting will disappear after a few weeks.
By running your TV it produces heat and this heat helps the panel to relax.
