The latest in HDTV technology, LED delivers deep blacks, bright colors and crisp images to rival any display category, and are the slimmest, most energy efficient televisions available. Improved motion capture allows smooth, natural pictures, even with fast paced action.

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

I had quite an ordeal over the last month attempting to purchase a new HDTV. I was looking in the sub $1000 range, wanted a 40-42" LED-Lit model and did a lot of research before settling on the Samsung UN40C6300.

I originally settled for Samsung over LG due to in-store picture comparisons and quite frankly, Samsung's great reputation over the past years. They were the pioneers of LED edge lighting and for a long time remained king of HDTVs. When my set arrived via Amazon (which was super simple by the way) and I set it up, I was instantly shocked and disappointed. The samsung model had the worst backlight bleeding I have ever seen in any LCD TV/Monitor.. ever.. Upon researching the issue further I discovered that Samsung now outsources panels and I got stuck with a horrible Chineese CN02 panel while the model in the store happened to be using a Samsung Branded IPS panel. I can't say for sure whether stores always get the better panel for display purposes, but this sneaky bait and switch should be illegal. Needless to say, the viewing angles on the horrible CN02 panel and the awful bleeding (spots the size of softballs scattered through the image). Furious, I set up an immediate exchange with Amazon and went back to researching.

Digging deep in Amazon's search, I stumbled across the LG 42LE5400 which was only $4 more then the previous Samsung model. What caught me about this TV over the previous was the following:
1) Same exact price.
2) Research indicated NO panel lottery and LG using superior IPS panels.
3) 2" Larger Screen
4) NetCast Apps (Samsung's only supplies these on higher-end models)
5) Wider range of inputs including composite-in
6) Matte screen (Yes glossy looks nicer, but I'd rather not watch TV in a mirror).

This is a great TV: awesome picture and features.

- picture brightness is great: I'm using it in a bright living room (with windows on either side of TV), and the LED screen is bright enough to watch w/o problem.

- overall features great: Assume I've gushed on about the picture quality, the number of inputs (including several on the side for easy access), the neat 'video mute' feature (under energy saver) so I can play a music CD on my DVD player and not have to see the DVD's stupid music screen, and so on. (Hmm, I guess I could play mp3s on a thumb drive directly from the tv itself; I haven't tried that yet.)

- Audio sync problem fixed via firmware: As others have mentioned, after 45min-1hr, the audio became noticeably out of sync from the picture; this seemed to be equally true for all inputs. It wouldn't get *worse* after more time, but it was bad enough that it looked dubbed. My initial hack was to switch to a different input then switch back to the program, and it would re-sync. However, after upgrading the firmware via the internet this problem disappeared. A few notes:
~ getting the internet connected took me a bit; even though DHCP should have happened at plug-in, I had to turn my wireless hub off/on in order to get the TV to get its IP address;
~ In order to trigger the firmware update, I had to press 'netcast' or 'widgets' on the remote; I think it was at that point that the TV automatically sought out the update.
~ it took two firmware updates in a row to reach the most recent version (6.0.something, I think).

- Noticeable delay lag for video games: about a tenth of a second or even a bit more (after some measurements and calculating).

So far, the picture quality is good to me, who never had LCD or LED tv before. So anything better than CRTV is kind of a "wow" to me. So, I dont want to write too much about picture quality.

There is one thing I felt betrayed about. There is nowhere in the product description tells that the "Wireless Ready" feature works if and only if one uses USB wireless adapter made by LG and no other USB wireless adapter. I purchased this "Internet Ready" TV with a hope that I would use a different wireless USB adapter that can be purchased for just $15. Now, I am shocked to learn that I will have to use only LG adapter that one can buy for about $80 in amazon.

So, when you purchase this product,keep in mind that you will have to spend another 80 bucks to make Netcast and netflix work. Although other option is to hook your computer to the TV by HDMI or AVI.

I hope this review help you make informed decision.

The LG 42LE5400 is my first flat-screen television, and I've only had it for a couple weeks now. So there are the caveats.

But to my eye, it's a beautiful machine -- with the power on or off. I'm the kind of person who wants the giant TV in my living room to look nice even when it's off; only Samsung sets can match this LG in the looks department. It's almost impossibly thin, and when powered off it's just a cool-looking black panel sitting on my entertainment center.

Turned on, it's amazing. I haven't noticed any blurring while watching sports or action, the colors are great, flesh tones look like flesh, and the blacks look more than adequate. I did have to fiddle with the settings some out of the box -- turned the backlighting way down, for example. But to me, the television's self-calibration system seems to work great.

The Internet apps are pretty good, if a little spare. The TV connects to Netflix, Vudu, YouTube and other Internet video using an Ethernet cable plugged into my wireless router. LG sells a separate wireless receiver that you can plug into the television to ditch the 10baseT. There are also a bunch of Yahoo! "widgets" that do things like tell you the weather and check stock prices. They seem relatively useless.

So: Five stars, for now. That could change depending on the television's durability; it's a new model, so it doesn't really have a track record.
