We disabled the Energy Saving option on our LG LB5600 LED TV so that we could control the luminosity of the screen ourselves. Otherwise, the TV adjusts it based on readings by its ambient light sensor. We used the Expert1 mode to calibrate the TV. We had to bring down the contrast option a little bit to flatten the gamma curve.
For cable content, enable both noise reduction features. Real Cinema should be turned on when watching 24p movies like Blu-rays.
Enable the Edge Enhancer feature if you are watching content below 1080p. It improves the upscaling a little bit.
The grayscale calibration was a bit off by default, and even after spending quite some time with it, it wasn't perfect. The following settings are panel-dependent, so you shouldn't copy them. Just set the color temperature to Warm 2.

How can I get the best picture and color?
Copying our settings will get you 95% of the way to your TV's perfect picture, and most people won't notice that last 5%. A professional calibration would also not be worth it for this TV. So start by using our settings, and remember not to copy our grayscale settings, as those vary by individual unit.
For the LG 42LB5600, please suggest the best setting to avoid LCD burn-in.
From a settings standpoint, there isn't much you can do to prevent burning-in. Contrary to plasma TVs, the luminosity setting doesn't affect the persistence of LCD TVs because it is the backlight that changes. The only setting that has an effect is the 'Contrast'. Reducing it helps prevents an overshot of voltage in the pixels. But the best way to prevent burn-ins is to make sure you don't leave still images displayed for a long time.
I just purchased a refurbished LG 42LB5600 and I can't figure out why I get the message "no signal" when I switch to HDMI2 to view movies from my laptop on the TV. I have my cable box connected to the HDMI1 port at the back of the TV and my laptop connected to the HDMI2 port on the side of the TV.
It's likely that your laptop is not set up to send the signal to your TV. First, make sure your HDMI cable is plugged in properly to both the TV and the laptop, and then see if the signal carries. If it doesn't, go to your display settings (Windows: Control Panel -> Appearance and Personalization -> Display)
(OSX: Apple menu -> System Preferences -> View, Displays -> Arrangement) and then choose how you want your content to display on the other screen.
If that doesn't work, you may want to try a different HDMI cable on Input 2, and try the cable from HDMI 2 on a different input. This will help you determine if the problem is being caused by the cable, the port, or the source. Please feel free to email us again if none of these steps resolve your problem.
How come my Dish box doesn't work with HDMI 1 or 2?
Try unplugging all cables from both the TV and the Dish box. Wait about 30 seconds, then plug them back in (including the HDMI to the TV) and see if it works. Make sure everything is plugged in securely.
If that doesn't work, try another HDMI cable and see if you get different results.
