lg hz what is the differance between 120hz and 60 hz? I know to buy the 1080p.

I assume the higher the Hz the better the motion on screen looks. Smoother vs. blur or pixelated.

I have the 55" LM6700 not the 47" but I have noticed that it does appear to be 60hz instead of the advertised 120hz. This doesn't bother me too much because I dislike the way 120 hz. looks. TruMotion is horrible.

Let me put it this way....Electricity in the USA is 60Hz. When you turn a light on, it actually has a flickering power. DO you see light bulbs flickering on and off? OF course not. The human eye see's 60Hz as "always on". So then what does 120Hz do? It may clear up video a little, but nothing more, and your results may vary. (Everyone's eyes are different). So enter 240 Hz. .... YOU CAN NOT SEE ANY DIFFERENCE FROM 120 TO 240hz. Period. It is so far beyond the human visual capacity its not funny. So 240 Hz is a MARKETING GIMMIC to charge you more.

Samsung uses their own "Rating" for their TVs. This TV is a Samsung 120 CMR which translates roughly to 60Hz. I believe someone at Amazon saw 120 and assumed it was Hz not CMR

Use 120Hz to watch movies and regular TV. The 240Hz is for watching sports with high motion. It really comes down to personal preference once you watch for a while you will figure out what bothers you about both rates. The new TVs allow you to turn the features off in the menu structure. There is only about a 30% improvement from 120Hz to 240Hz. You have to experience it to make a decision. Go to a big box store and make the change in the menu to allow you to see the difference.

it should be 60hz. look at panasonic's page http://shop.panasonic.com/shop/model/TC-L47E50?t=specs. Amazon should have this fixed. I bought it cos I think it's 120Hz

Hz refers to the screen refresh rate. 120 hz means that the screen is "refreshed" 120 frames per second. 240 hz refreshes the screen at the rate of 240 frames per second. The purpose of the increased hz is to smooth out picture motion. The step up from the low-end refresh rate of 60 hz to 120 hz can often be noticeable, especially with fast-moving sports events. However, I can't tell any difference in going from 120 hz to 240 hz---I know that there is a difference; it's just that my old eyes can't tell the difference! Hope this helps.Charles

I had tried this TV but the 120hz wasn't fast enough for me. I returned it and purchased the 240hz model 7100. It's more expensive, but the picture looks much better. I'm very happy with it. It will give you the effect you mentioned.

Excellent question! My invoice (purchased late Jan.) also states 120Hz, but I just looked on the back of my set and it clearly indicates 60Hz. Interesting.

I spoke with an LG rep online and here's what they had to say: "This unit model 42LN5400 is TruMotion 120 Hz. It isn't native 120 Hz. There is no audio visual device that outputs more than 60Hz on market, that's why TruMotion is video software on the TV that doubles frames. TruMotion is video processing software. TruMotion up-converts the input video by creating new frames to create smoother motion." No device on the market that outputs more than 60Hz?? Draw your own conclusions. I bought this tv but am thinking of returning it - unopened.

No this model run on 120 hz. I love this TV ~ great for my viewing. I'm not a gamer.

I agree, Tiger Direct has it listed as a 120hz TruMotion as well: LG 47LM4600 47" Class LED 3D HDTV - 1080p, 1920 x 1080, 16:9, 120Hz, 4000000:1, HDMI, USB, 4x 3D Glasses Included, Energy Star. I confirmed it for sure on LG website: http://www.lg.com/us/tvs/lg-47LM4600-led-tv/technical-specifications

I am having the same problem. I purchased a 40" LCD LED HD Samsung 120Hz 1080p and when I turn my TV on it shows 60Hz 1080i. And I still don't understand what is wrong. How can I fix it.

The input feed is always 60Hz, and that's what it's telling you. 120Hz is the refresh rate internal to the TV, so your TV up-converts from the 60Hz internally.

The Samsung that I purchased has the 120HZ refresh rate. I can take a picture of the box that it was shipped in if you like.

Then you'll be fine with the 60Hz. The best thing to do is stop in a store and see if you can notice the difference between 60 & 120Hz. But read some reviews on the 60Hz and you'll see that there's no mention of blurry pictures, etc. Save your money and just get the 60! That's my .02. Good Luck!

Depends on 2 factors: The graphics card you have (like GTX 700, 800 series or Radeon R9 series) are capable of 4k @ 30hz. However, LG is hiding the refresh rate @ 4k. 120hz is the refresh rate that will go down to ??? when you have it at 4k. Likely it's 30hz anyway, so you should be ok. Btw, HDMI 2.0 is needed for 4k @ 60hz and there's no video card out today with HDMI 2.0 out.
