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

It took me about three days to decide to pull the trigger on this TV after looking at written reviews on Amazon and even some video demos online. About four hours after receiving it and I haven't left my room.

This TV is simply lovely so far. The setup was a bit confusing at first and the stand is not the best I've ever seen but the instructions for setting up the stand were adequate and I was able to get the TV up and running in about ten minutes (the first five of which I sat confused).

Really, the negatives on this purchase stopped after the setup and the stand. Besides the stand, this TV is just pretty. One of the first things that stood out to me was the fact that the screen is so sleek and does not reflect any glares at all. Also, I had read about a terrible viewing angle and I honestly watched this TV from the side with no difference in the picture at all. It's so big that it's practically impossible to have a bad seat in the room that you watch this TV.

If you plan on playing video games on this TV, you will not be disappointed in the least. The only issues I've had with the TV is getting my colors juuuust right, although the "Game" picture setting has sufficed very nicely.

The sound on the TV is great. It is centered and doesn't feel empty in the least. It is a very full and rich sound that will work just fine if you don't have an expensive surround sound system.

After paying [...] and receiving free two day shipping, I am literally ecstatic that I was able to nab such a nice TV. After spending the last three years with a 24" Insignia LCD that was 720p, I am ready to lock myself in my room.

If you are like me and can't shell out more than 500 dollars for an HD TV, this is the TV you want to pick up right away.

First off: We did not purchase this TV from Amazon, we purchased it at a local retail store, not for any other reason than the price (we paid a few hundred less than the current Amazon price)

My husband and I purchased this back in April, it was either this or the Phillips that they had set right beside it, it was really a hard choice as the Phillips was marked down to just a few hundred dollars, whilst this was just under six fifty. We are so very glad that we went with this model(42LD450). The video quality is quite good, blacks are black, and whites are white, back light is very bright, and video quality is amazing.

We almost took this back however: When we first plugged it in and turned it on, the only picture was a white screen with the Firmware version bouncing around, no menu would come up and it would not acknowledge anything had been connected. Well, we unplugged it again, and turned it back on, and this time, it acknowledged the DVR (input 1) and starting spewing forth video and audio We have had no problems since that.

My only gripe is that we will have to go out and purchase a new unit for our surround system, as the TV only has a Optical Audio Output. And on that note, the built in speakers are not awesome, yes, they are very usable, but like almost all TV speakers, they are not going to satisfy your need for spectacular surround.

This is definitely worth the buy, I really think you will be happy with your purchase. Thank You For Reading.

I purchased this TV to replace my 3-year old Samsung Series 3 32" LCD TV in my master bedroom because I wanted a larger size TV now that prices have dropped a good bit (paid over $1,400 for my 32" a few years ago). I debated between this one and a 40" Samsung for the same price, both were 60hz models, which is fine since I'm only using this for my DVR. Since I've seen a few older LGs before that had decent picture quality, I went with this one for it's larger size with slighly better specs than the Samsung, although I've always preferred Samsung. I figured since this was a newer model than those I've seen, with better specs I couldn't lose.... I was wrong!

I put this one on the wall where my old one was and my first night watching it I was quite disappointed! Although the picture is sharp and vibratant, it's only that way if you are directly in front of it. The viewing angel is terrible with this set, especially vertically below, which is my problem since I'm using this on a wall in my bedroom and viewing it from the bed, which puts me slighly below the screen (the TV is just above my dresser, maybe 3 feet above the floor). In this position, the screen washes out terribly, much like some of the older laptop displays did. Blacks become gray and colors very washed out. My Samsungs don't have this problem, neither my old 32" or my 52" in the living room. The construction itself is also very flimsy compared to the Samsung models I've owned. It's strange though, that I installed a 42" LG for a friend that's over 2 years older than this one and it was much more solid and has a better picture and viewing angle than this one.

This is my first HDTV purchase and am pleased so far. (Read as I don't know much about this). Setup was simple; the price was right and it has some popular energy-saving features.

The picture was sharp and clear. Multiple preset modes (cinema, game, normal) make setup easy, but there are also custom, fine-tuning adjustments available. It does not appear to have network/internet capability, but I will purchase a Blue-ray DVD player with that feature separately. The unit has an optical audio out so I can use my older receiver for 5.1 sound.

The remote feels cheap, but gets the job done. I imagine one rarely uses the manufacturer's TV remote so LG (and other makers) probably do not spend much on them. I did not notice any backlight seeping out of case which I understand is a problem on some TVs.

For an entry-level buyer, this was a solid purchase. I paid $658 - I thought that was reasonable for a 1080p set in 42". I rated it 4 stars on because I do not have much product knowledge (yet).

01/11/2014 UPDATE: TV still has a sharp picture and vivid color. I am very impressed with both of my LG tv's. Highly recommend for budget-conscious individuals. My next TV purchase (hopefully more that 5 years down the road) will be an LG.
