MATTE or GLOSSY?

Answer: 
The screen is glossy. However, it is not as bad as a plasma TV. I have not noticed much reflection, but I have found with higher quality TV's it is better to have your lights behind the television. I would not let the gloss screen deter you from this purchase, it is a fantastic TV

Answer: 
Glossy, so I don't recommend you place this tv in direct sunlight. The glare is terrible. We just close the blinds near the tv during the day, the picture is great!

Answer: 
That number is total irrelevant as each brand creates his way of measuring the contrast ratio. As you no there is no standar to apply to all TV brands to measure that. What do you need is to go to a store a see the picture your self. Take one or more DVD/Blu-ray and play them and see for yourself.
With this TV you have so many tunings that I even had used them all.
You can tune the darks and the whites separately!

Hope this helps

Answer: 
It used to add much more to the price. I've seen it drop though in the passed year. It is a great feature when playing blurays.

Answer: 
120 hz runs around 999 for this size tv, 240 hz is 1499. It is worth the difference in price for 3d tvs.

If I have an Intel WiDi-enabled laptop, can I connect to this TV and use it as a dual screen without connecting it with a wire?

It says on intel's website that all 2013 LG TV's support WiDi. Is this true? If so, would I not need an adapter like the NETGEAR Push2TV adapter to connect with it?

Answer: 
Actually you do not need any extra equipment. I didn't realize the tv had this feature until a couple of weeks ago. Automatically reads your device.

Answer: 
Hello lgtvninja!
I happened to have the same tv and yes, you should be able to connect via WiDi ( wireless display) as long as both devices are on the same network. Open the program on your laptop and look for the device, once it finds it then a prompt will be displayed on the Tv; after you accept the laptop screen should come on. FYI image may be not as expected since most laptop has less resolution than the tv, but should be enough. Have fun!
