If you've been hearing about how amazing Blu-ray entertainment is, or how much better your favorite shows would look in HD,

SAVE MORE THAN ENERGY.
Earning the ENERGY STAR means a product meets strict energy efficiency guidelines set by the US Environmental Protection Agency and the Department of Energy.

UPDATE 06/26/2012: I have been really enjoying the TV for about a year now and am still amazed at the picture quality. I did contact LG recently about any harmful emissions or radiation that might come from the screen (as I use it quite a bit for both TV viewing and as a PC monitor), wondering if I should buy protective eye gear (I had been using various lens but decided to ask them before I purchased another pair....I had 2 pair break). They wrote back the same day and said that there is virtually no radiation from the screen.
End of UPDATE.
The set up is fairly easy although I found the manual to be lacking in more detail, especially concerning a better explanation of some of the features.
The HD picture is just AWESOME and BEAUTIFUL. I thought the screen might be a little too big for my computer but I was totally wrong....it is just great! I do not have a HDMI connector for the PC, only the RGB, but it is still just outstanding. Hook-up was a matter of just connecting the plugs.
The sound is better than good, but not great. (BELOW you will see how I was able to improve it....QUITE A BIT!!)
I was going to give it 4 stars because the non-HD channels are just good, and acceptable; but, the more I look at it, I realize it is actually pretty good. So, it warrants 5 stars.
I have seen a number of HDTVs, especially in showrooms, and this one seems to be better than those. It truly has an amazing picture with HD and I am very pleased with the purchase.
UPDATE 07/09/2011: After tinkering with the set for a month or so, I have been able to improve the sound CONSIDERABLY.....and it was pretty good to start with. Here's how I did it: Press "Menu", then "Audio". Turn "Auto" sound OFF! Next, I have the "Clear Voice II" turned "On" and set to 0 (the more I increased it to the maximum of +6, the more background static I got). MOST IMPORTANTLY, I use the "MUSIC" mode..this produces a much more dynamic sound! Then adjust Treble and Bass to your liking and CLOSE. I get a really great sound. I use 56 treble and 89 bass.
This is a 10/29/2012 UPDATE: I had ordered the Bose SOLO one piece system which is a single unit dedicated to increasing TV sound quality. I followed their instructions to the tee and used the best connection they recommended, as well as turning off the TV speakers when testing the sound. Oops.....the LG had a nicer and more dynamic sound! I have since returned the Bose system (they were great about taking it back....even paid for UPS return postage). Actually, the SOLO unit has gotten some bad reviews on here, even though more good than bad.
UPDATE 10/31/2012: After messing with the "Video" for over a year I have finally gotten what I consider to be a better picture than the "Standard" or "Intelligent Sensor" modes. Basically, I use the first option of 16:9 Ratio....then skip using the "Picture Wizard" (it is quite involved but it might work for you)....and chose the "Vivid (User)" option for the viewing mode. You can see what you like under the various adjustments of "Sharpness", "Contrast" etc.. Under "Advance Control", I have all the options set on "High" except for "Black Level", which I have on "Low". Then "Close".

I must preface my review by saying I didn't buy the LG 450 online, I bought it at a big box store because they had a better price:
I wanted an inexpensive TV for the bedroom and the LG 450 is a good choice, the picture quality is very good for it's price. I didn't need 120Hz so I saved $150 by buying the 60Hz model. The LG 450 has Expert ISF Settings so you can have it professionally calibrated or do it yourself, it has a built-in blue filter and calibration wizard. The ATSC tuner is very powerful because I get all the local stations OTA with an indoor antenna. This model is not internet enabled so you need a set top box to get Netflix, etc. As with all TV's the sound isn't great but it does have bass and treble controls. The USB port supports: JPG, MP3, MPG, MP4. The manual states other video formats are supported but they wouldn't work on my TV.
Inputs:
HDMI(3)
VGA(1)
USB(1)
Component(2)
Composite(2)
Outputs:
3.5mm headphone
Toslink optical
I recommend these basic settings(YMMV):
1. Turn off Dynamic Contrast.
2. Turn off Auto Energy Saving.
3. Turn on Real Cinema, if your Blu-ray player supports 24p then turn that on as well.
4. Select Just Scan.
5. In Sound Modes select Music or Cinema.

== UPDATE 2/22/13 ==
After owning this TV for about a year now, I my recommendation still stands. Runs like a champ, I haven't had a single issue. I will probably not upgrade for another year.
== Original Review ==
I honestly didn't know what to expect. I bought this TV on sale at Best Buy for 100 dollars off. I was in the market for a new TV, actually my first TV purchase.
After a week of use, I am very very pleased with my purchase.
The picture quality is fantastic. Every aspect of the picture can be customized- how warm the picture is, brightness, gamma exposure, etc. Let me say, out of the box the picture was great, this options are more for if you are very particular.
The sound quality is adequate. Not the absolute best, but it is a very solid TV. My dad's bravia's sound quality is a lot worse so I am thankful that this setup is good.
As far as features are concerned- it has all of the standards (sleep timer, auto-on/off, etc). It is missing picture-in-picture but this seems almost irrelevant for the size of the TV. I am throughly impressed with the number of inputs and outputs on this TV. 3 HDMI ports, 2 regular RCA (red, white, yellow) inputs, and the PC cord. The PC cord input even has a headphone audio input! This makes using my long cord very easy and converter free.
As a note, I use the TV with my PS3 and PC, and both look and sound fantastic.
I am very pleased with this purchase and would recommend it to anyone.

I upgraded from a 19" tube tv and this has been fabulous. Slight difficulty watching dark movies but that could also be an issue with my DVD player. Very worth the money
