Which Size HDTV is Right for My Room?

HDTV Size chart
With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience.

If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get.

  • Minimum size = Viewing distance/3
  • Maximum size=Viewing distance/1.5

Might not appeal to the people who can afford a $2500 TV..aka the videophile, but I'm in love with this. For 95% of people this should be more than enough. After months of shopping around and doing my homework, I went against the grain and decided to try the LG. Purchased this set through Walmart site to store. It was $70 more than the LD450 model on the shelf. But in my eyes well worth paying a little extra and waiting another week for it. The extra hdmi port alone justifies the $$$$.

Picture Crisp! Bright. Color is deep! Pops off the screen when in high def. Nothing in 480 (standard) looks good on this though . Keep that in mind. Initially struggled with adjustments. In the end a couple of tweaks to cinema mode were all it took. Looks as good (maybe better) than the comparible Sony's and Samsungs.

A word of advice... I saw one of the 450 models on a store shelf...which basically has the same picture with a few less features. It looked horrible next to a Sony. Huh? The sales guy tried to tell me that the LG wasn't getting as good of a signal. Ummm...why does the 47" inch version way down on the other end also look bad next to the Sony? Or even the Sanyo? Why do I see the same thing when I visit the store down the road in fact? The answer? LG's 'store demo' presets are horrible. I'm not sure why they did this. But they badly misjudged something. Once you get the picture correctly adjusted, you'll see what I'm talking about. It's an "oooh and ahhhh" kind of thing when you see what it is supposed to look like.

I spent close to an hour in the store comparing LCD TVs. This LG stood out with its sharp and bright colors. I used the store's Internet connection to check out the reviews but since it is a new model there wasn't many. The older model however was popular among gamers.

The speakers on this TV are hidden on the back and this gives it a neat look. The speakers also sound great. There are different sound options in the menu plus advanced picture controls. In "Intelligent Sensor" mode the TV adjust the brightness and color contrast according to the room lighting conditions. The picture quality is easy to setup using the picture wizard option.

This TV has three HDMI connections in the back to use with your laptop or desktop plus an RGB (VGA Cable). There is also a USB 2.0 port in the back. I connected a USB thumb drive and was able to listen to music and display my digital pictures on the screen.

Over all I am very pleased with quality of this LG model and recommend it to anyone who wants to buy a LCD TV for under $1k, and I mean not for picture quality but the size of the screen since this had as good, if not better, picture quality as other more expensive models in the store.

I bought this TV from the big box retailer that constantly rolls back prices. The TV was actually cheaper than online. Overall I like the TV very much and I think the value proposition is excellent. My local Bestbuy had this TV on display.

I have three recommendations for people who are not technically inclined - like myself - and get this TV to utilize the TV's full potential:

1. Make sure you use an HDMI cable to connect this TV to your cable box. You need to make sure that your HDMI cable is at least version 1.3.
2. Get HD cable or satellite. Having HD channels makes a huge difference.
3. Make sure your cable box is set at 1080p output signal. Our cable box was set at a much lower picture quality and it took me a while to figure this out. Some cable boxes might adjust the output signal automatically, but not all do that.

If you follow these three simple steps you should be able to enjoy the full potential of the TV. Also, think about getting netflix and one of the blue ray players that allows you to stream netflix. The quality of some of the movies is just awesome.

My last recommendation is to get an additional warranty. LCD TVs seem to be more prone to failing than CRT TVs. There are huge differences in the cost of these additional warranties. So account for these differences in your comparisons when you shop around.

Picture looks great crisp contrast, vivid bright colors, excellent sound would recommend this TV to anyone. My only complaint is the lack of analog audio output connection.

Product arrived safe from California (we're in Illinois) in 4 days. Perfect condition. Took only minutes to install, replacing an old Sony set with CRT. Light enough to carry and exceptionally flexible. After channel scan (about 10 minutes), it was ready to play HDMI link to cable, HDMI link to laptop, DVD player, and videotape player. Picture quality is outstanding. Remote is self explanatory. Vastly superior to many other 42" sets that I've seen in stores and homes of friends.

I've had my eye on this TV for about a month now. I saw it at Fry's on sale for 499 about a month ago while I was just browsing around. I was tempted to buy it, but without permission from the wife... it could've been a bad idea. Went back two days later to get it but the sale was gone and the price was back to like 799. I was so mad. Last night I went again for some other things, to my surprise they had this TV on sale again for 499! Wife was with me, we talked- we got it.
This TV is all around great. We have it in the bedroom, and the thing I like best about it so far (besides the amazing value and great picture) is the intelligent sensor. It allows you to save power (and your eyes). When it's dark in the room it dims the screen to save power and not to be overkill on your eyes. AWESOME. Our plasma was so bright and a hassle to adjust settings all the time so I just dealt with the brightness. This power saving feature can be turned off, but leaving it on auto is the smart thing to do.
Other than all of that, speakers have come a long way in built in LCD TV's. I'll have to say these sound about as good as my 46" Samsung in my office- which was a pricier purchase. If this is going in a living room or game room, a sound bar or full surround sound would always be better- but for basic TV watching the speakers are more than adequate.
As most people will say the 120hz is iffy. At times people look to be moving faster than they should, or there are little distortions. I think it's best used on blu ray, but I generally have that turned off.
If you're in the market for a TV- go to Frys ASAP and grab this for 499. The price Amazon has is fair, but Fry's price was unbeatable and I couldn't resist....
