Answer: 
Go into Picture settings and turn off the energy saver. Not sure why these tv's have it most of this size are energy efficient by nature. Doing this you should notice a difference. The energy saver darkens the screen to save power.

Answer: 
You can brighten up your picture a few different ways...

GO through Picture WIzard and set up the picture.. once you are done with doing that, you can adjust the backlight (if necessary)

The quicker way would be to just turn energy savings down to medium, minimum or turn it off completely. Personally, I use medium during the day and maximum at night... but it's all personal preference. Also i noticed for video games and watching TV in HD, turning the sharpness up to 85+ makes a huge difference.. I have my sharpness (both V and H sharpness) set to 95 and it looks amazing. I sometimes adjust it for less HD things like basic cable/non hdmi dvds/etc... i then turn it down to about 75.

Hope I helped.

Answer: 
To increase the brightness, deactivate the Energy Saving mode, as this feature automatically reduces the brightness of the screen to conserve energy.

How much visual difference does the 120 Hz make compared to 60 Hz?
Asked by another customer while visiting BestBuy.com

Answers

Answer: 
One advantage of 120Hz over 60Hz is the frame-rate of 120Hz is divisible by 24. Why is this important? Movies are generally filmed at 24 frames per second. with a 120Hz TV, it will display 1 frame of the 24fps 5 times [120/24 = 5] (It's technically called a 5:5 pull-down). it perfectly recreates the true look of the movie. With 60Hz, it is not divisible by 24 evenly [60/24 = 2.5] so the tv has to display the first frame 3 times then the 2nd twice. this creates a "judder" in the image( We call this a 3:2 pull-down).

On another note, as far as noticeable frame-rate, your eye can only see the difference up to about 60-85Hz when It comes to TV's. much like when you play, for instance, a First-person-shooter game on a computer, you can't detect the game getting smoother greater than around 60 frames per second (60 fps and 60Hz [cycles per second] are the same for those who don't know)
Hope that helps!

Answer: 
Personal Preference; some people do not like what 120hz does to video. I myself enjoy it and feel it makes the motion look much sharper. Relatively little blur occurs with 120hz.

Answer: 
There are double the amount of frames per second being displayed, which gives a smoother picture overall. The increased refresh rate is a personal preference, but there is enough of a visual difference to notice. See if you can make your way into a store to get a visual demonstration and see for yourself.

Answer: 
I recommend using Picture Wizard and then it will prompt you to use the "expert" picture mode.. Standard picture mode may be your problem... try VIVID before you do anything. and see if that improves...

there are alot of different settings on this TV to adjust the picture and it took me a few hours, but i finally got it perfect..

Answer: 
There is a status light that wraps around the bottom right edge of the TV's frame. This turns red when OFF (aka Standby) and blue when ON. If you are a seeing a red light elsewhere, then yes that does not seem normal.

If it is just the status light, then you can turn it off if you wish by pressing the "Home" button on the remote and going to "Option" and then "Power Indicatior" -- you then have the option to turn the light off when the TV is on, or when the TV is off, or both

Answer: 
The only known light on this television, that is red, is the standby light. If this light is not interfering with the operation of the unit, then it would be cosmetic only in its nature. We can look into having the unit inspected by a service technician, but it is likely that the manufacturer’s limited warranty will not cover such adjustments. However, if you would like to check, then please contact our Customer Interactive Center at 800-243-0000.

If you want high definition for your HD content, games and Blu-ray entertainment, there's nothing better than 1080p Full HD. And if you want sports and fast action to be as a crisp as they are exciting, TruMotion 120Hz virtually loses the blur and keeps the sizzle. The LK520 1080p LCD TV brings you both along with the other great features that make LG TVs something better.
