Anti-theft Kensington Lock
A Kensington Lock is a physical device that can be used to protect the TV against theft. Look for the Kensington slot on the back of the TV. The slot has a K icon next to it. Wrap the lock around an object that is too heavy to carry and then thread it through the TV's Kensington slot. The lock, however, has to be purchased separately.
The method of using a Kensington Lock may differ for each TV model. Refer to the Kensington Lock manual for more information.
Display Resolution
You can also select one of the standard resolutions listed in the Resolution column. The TV will automatically adjust to the resolution you choose.
LED 5300 series and above, PDP 5500 series
After connecting a computer to the TV, set the screen resolution for the TV on the computer. The optimal resolution is 1920 x 1080 @ 60 Hz. If it is set to any other than in the table below, the TV may display nothing. Set the resolution properly, referring to the user guide of the computer or its graphic card.
