LG 55UF950V User Guide

You may find different brightness and color of the panel depending on 
your viewing position(left/right/top/down).  
This phenomenon occurs due to the characteristic of the panel. It is not 
related with the product performance, and it is not malfunction.

Displaying a still image (e.g., broadcasting channel logo, on-screen 
menu, scene from a video game) for a prolonged time may cause 
damage to the screen, resulting in retention of the image, which is 
known as image sticking. The warranty does not cover the product for 
image sticking.  
Avoid displaying a fixed image on your television’s screen for a 
prolonged period (2 or more hours for LCD, 1 or more hours for Plasma).  
Also, if you watch the TV at a ratio of 4:3 for a long time, image sticking 
may occur on the borders of the panel.  
This phenomenon also occurs in third-party products and is not subject 
to exchange or refund.

“Cracking” noise: A cracking noise that occurs when watching or turning 
off the TV is generated by plastic thermal contraction due to tempera-
ture and humidity. This noise is common for products where thermal 
deformation is required. Electrical circuit humming/panel buzzing: 
A low level noise is generated from a high-speed switching circuit, 
which supplies a large amount of current to operate a product. It varies 
depending on the product.  
This generated sound does not affect the performance and reliability 
of the product.

Do not use high voltage electrical goods near the TV (e.g. electric 
mosquito-swatter). This may result in product malfunction.
