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

This is my first HDTV, so keep that in mind - I was bound to be wowed by HD, no matter what the TV. But I really like this one. It has excellent specs (high contrast ratio, 2.7ms response time, 120 Hz) and a 'picture wizard' that seemed to do a great job in calibrating the picture settings. It supports the latest HDMI specs, and has some nice features like Real Cinema (which maintains film's 24 frames per second when watching a movie with a compatible source), and also the ability to tweak the settings of TruMotion, LG's image interpolation system.

Interpolation is what 'smooths out' video on HDTVs - it actually creates additional frames on the fly to fit between the existing frames of the source, and it's what can give HD material that documentary/soap opera quality. Sometimes that's desirable, but other times it just looks bad and cheesy. This TV has Low, High, and User settings for this feature. I was able to tweak the User setting to a good compromise, that smooths out some of the blur and 'judder' effect of normal video, but doesn't make it look artificial. There are lots of other settings to tweak, for audio (downmix preferences, dynamic range, etc.) and everything else. This brings up the user interface. The menu system on the TV is very user friendly, and graphically attractive. The remote control is one of the best I've used - it has just enough buttons, while being well-laid out and thin and light, and fits nicely in the hand. The 'arrow pad' to move left/right etc. has comfortable buttons and works well (remotes often screw that section up, for some reason, but not this one).

My favorite feature has to be the networking/Internet capability of this TV.

TV is great for the type (LCD) and price. The picture is bright, good contrast, and very smooth. The menu/remote are very comfortable...overall the picture is very nice. Aesthetically, the TV looks great as well...no cheesy features or decorations. This is my first LG product and I'm very pleased with this set. Also added the wireless adapter ($70). The entire setup and interface are very intuitive. This is a kids TV and they had Netflix down in no time (even the 5 year old). My only wish would be a backlit remote control.

Only complaint at all is with shipping. It did not ship on time and there was no communication from the shipping company. Ultimately, I had to contact the shipper to make an appointment (was stated that they would contact me). Once I called them, they drove it over the next day (Saturday). All in all, still very pleased.

I bought this TV a few weeks ago after reading many nice reviews about it, and while it's nice, I found its features disappointing.

To start with the good part, this TV indeed looks great both on and off: its no-frills design is very elegant and will make it look good in every living room, its picture quality is amazing. I can't really comment on the sound since I don't have good speakers, but I'm not even missing them with the built-in speakers. Its TV-related functionalities and interface is also nice, with zillions of options to set the picture and sound to your liking.

However, the selling point of this TV is supposed to be the built-in software for online applications (called Netcast), and Netcast on the 42LD550 is a major letdown. At the time of this review LG doesn't have model-specific information on the Netcast features available, only a generic all-promises page with the fine print "features vary by model and product category". Now, Netcast in principle has at least three different video-on-demand services built-in, as well as internet radio, and many other great features -- but this TV has almost none of these included! (I'm using the latest software version, as it updates itself automatically.)

Netflix is included (that's the one extra star), and there is a dumbed-down version of Vudu, which only includes the movie rental features, but nothing else. (For example, there is no Pandora, even though it is included in the "real" Vudu application, it's only left out of the LG version). The rest are useless "apps" and a few selected Yahoo Widgets (all the good ones are missing, the best is probably Weather), Flickr, Picasa, Youtube and Twitter (twitter on a TV??), and that's pretty much it.

I had been planning on buying a new tv for quite a while, and did as much reading and research as time would permit. I kept coming back to the LG 42LD550. What really sold me on it was the Netcast (powered by the WiFi USB dongle), super-high contrast ratio, wireless-ready, and the price. The price! Man, a tv like this would have cost several thousand dollars a few years ago.

At any rate, I've been working this set for about 2 weeks now, and I love it. The picture quality is amazing, it's very responsive, the remote is very good, and even the speakers are decent. If you spring for the wireless box, you have the option of mounting it straight on the wall with no unsightly cables hanging off of it (or being routed through the drywall). Now it makes for a beautiful centerpiece of my entertainment center, which the wife loves to show off (win-win).

The World Cup is going to look mighty nice in HD on this tv!
