Size Name: 32-Inch Verified Purchase
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!

Size Name: 42-Inch
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.


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.

Size Name: 42-Inch
I've been watching HD TV and movies from the LCD monitor on my computer for the last few years because I vowed I would not spend more than $500 for a boob tube, but now I've finally found something that I would be happy with for $499. This LG is a very basic, no-frills TV, but it's all that I need in a TV. The features are very base level and the specs on the contrast may make it seem like it has a phenomenal picture but it's really just average for this price range, which is to say that it's perfectly adequate. It's basically what you would expect from an IPS panel. You can move around the room and the image is perfectly viewable no matter where you sit. The backlight is adequate and turned all the way up is not glaring.

One of the first things you'll notice is that the power "button" is not a button, but a touch-sensitive area that requires no effort to turn on. That's nice because the TV is so light that pressing a conventional button on this TV would probably move it around a tiny bit. The TV takes a few seconds before you see an image but that's quite tolerable. Changing channels is about as fast as other recent TVs but definitely slower than a computer with a USB tuner. That's perfectly fine for me since I don't intend to channel surf with this TV.

It's nice that the unit offers a calibration wizard but I did not like how the recommended contrast setting made darker images lose detail. I ended up turning the contrast almost all the way up. There's really not much to say about the image quality. It's perfectly decent and I didn't find any noticeable flaws. So far I've mostly used it to play Lego Batman and there is no image lag that I've read about in other TVs.
