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

Product Description

While this is my first HD TV, I have been looking at them for a while. I have had trouble justifying replacing a perfectly good 27" Sony. However, now that the networks are moving actual content into the bars that fall outside the range of what my SD Sony can display, I finally got tired of missing 1/3 of the show and decided it was time to upgrade.

I am a Netflix subscriber, and I have been using PLEX to stream Netflix content onto my TV as well as to stream other video content stored on my Mac to my TV. It works very well, but it is a little kludgey since I still want to be able to use the Mac wile using it to serve Video content to Plex. (The TV acts as a second monitor.)

I was VERY concerned that I could find no reviews about this unit anywhere. It's just that new. I was especially concerned about how well the 'net connectivity worked. So, now that I have one, I thought I would write a review.

It's an LCD HD TV. Picture quality looks fine to me, but standing in the store, they all kind of start to look alike. I'm not a video quality expert, I would say that I could see a slight improvement on the LED TV's over LCD, but I don't think it's drastic enough to warrant $500-$1000 premium. I was more interested in spending extra to get that Ethernet port on the back.

So, how does it work? In a word: Amazing.

I hooked my HD cable box up and got that working, then I plugged it into my home network. It recognized that I had plugged it in, and it DHCP'ed an address off and connected without any problems. I hit the Netcast button, and got my choice of Yahoo Widgets (There is also a Widgets button on the remote) Netflix, VuDu, YouTube and Picasa.

This TV is great! The picture is very clear. To prove it, just play Avatar in Blu-Ray and you'll see what I mean. What makes a difference in this TV compared to the old 60Hz TVs, is the 120Hz refresh rate on this LG model. The 120Hz refresh rate makes a big difference when watching TV. Motion is very smooth and characters and objects in the picture are very crisp and clear. The TV has a couple of good brightness levels to choose from. The nice matted screen also prevents screen glare. There are other TVs that put on that shiny surface which could take away the nice viewing experience but who wants screen glare while watching a nice movie or show? Should you consider an LCD screen over an LED screen? With this LG model, LCD looks just as good as an LED set. You won't get the deep blacks and energy savings that LED TVs can provide, but the dark colors are already excellent and LCD TVs have been developed over the years to be more energy efficient. Plus, you'll spend more on an LED TV if you get one. I would say wait on buying an LED TV if you don't want to spend an extra couple of hundred dollars, and if you don't mind not having the high contrast ratios. Plus the prices of LED TVs will go down in the future. The sound is decent. The sound scale goes from 0 to 100. 25 will give you a decent sound from about 10 feet away. It's loud enough to hear what is being said but could be loud to possibly wake a baby in the adjacent room. Depending on what's showing on the screen, you might have to go to 50 to go louder (though you might want to respect your surroundings because this level can be loud for your next door neighbors). This TV set has different audio options to choose from. You don't really need to connect to a home theater unless your an audio enthusiast and want better sound.Read more ›

I ordered this TV thinking I was compromising and would just put it in my bedroom after a couple years and upgrade the main TV anyhow. Boy was I wrong! This TV, when hooked up through HDMI, has an amazing 3D like picture with dark blacks and vivid colors. I am beyond shocked how well the picture and quality is for the price. The widgets and streaming video also work well as I purchased the wireless adapter and it took only a couple minutes to hook up to my wireless router. Overall I cannot recommend this TV more highly!!!

We purchased our LG in October, worked beautifully and we truly loved it. Then it went out in January and since it was just over 90 days could not return it. We called LG for repair and they came out promptly but were unable to fix it, since then, we have had nothing but the run-a-round. It has been 3 weeks and we are still without a TV and we were told it would be another 2 to 3 weeks before we get a replacement. I don't think this is acceptable service, if you sell a defective product and are unable to fix it you should replace it immediately and if you can't you should refund the money. If you want to save yourself a lot of frustration, purchase another brand, even though the picture is beautiful, if the service isn't good it isn't a good buy.

The 46" LG LCD 120 Hz/1080p is my first HD TV. I wanted to make the right choice for my budget, and spent hours and hours looking a different brands and models, comparing prices, and reading countless reviews before deciding on this TV. All I can say is that all of my experiences so far indicate that I made the right choice. The HD picture is exceptional, there is virtually no glare on the screen, and the set-up is extremely user friendly. If you are looking for a fairly large, high quality TV for HD television, Blu-Ray, and PS3/Xbox360 for around $1k, this is the TV for you!
