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 received my LN40B750 this past Friday and have now had all weekend to kick the tires and be amazed at its capabilities. I had already submitted a review, but not sure where it went.

As I had stated in my now missing review, I am very impressed with this set's image quality and ease of use. Setup was pretty easy and only required me to fasten 4 screws to mount and lock the base to the bottom of the set. Connected the optical out to my receiver (Yamama RX-V750) and ran my DVD player's component cables right into the set. Now, I can finally enjoy progressive scan mode. What a HUGE difference that made! One thing I have to address is a negative comment made by another person who was complaining of stereo output from the optical out jack, instead of 5.1 surround sound. This is 100% contingent on what the broadcaster is pushing out, NOT the TV. Yes Jimmy, the evening news ONLY needs to be in plain vanilla stereo, not 5.1 surround sound. I can confirm that it does push out L/R stereo on the evening news and certain other broadcasts. Some broadcasts caused only my center channel to push out audio while others gave me L/C/R output so don't blame Samsung at all if you're getting stereo or 3-channel output. Watching ZOOM last night made all 5.1 channels on my receiver light up like a Christmas tree. I am so thrilled to watch some of my favorite shows in 5.1 now.

So, one of the main reasons I bought this was because of the 240Hz processing and 2ms response time, and, on my wife's recommendation, the panel design. 240Hz processing it is both neat and surreal. Other reviewers have stated that it give the picture a sort of Soap Opera-like effect but I would have to say no to this assessment.

Wow! This panel is really amazing. I have been researching sets for several months. It came down to the Sony XBR6 and the Samsung A650. Quite frankly I loved the Samsung picture but could not really accept the red "Touch of Color" bezels... just a personal choice I guess. Anyways, I purchased the Sony a few weeks ago on clearance and thought I was getting a great deal. Unfortunately the picture on the Sony was a real let down. It seemed dull and dim (even after adjusting the settings several times per different recommendations online and turning off the auto-dimming setting). My old DLP set even seemed crisper when I compared them side by side which was just not acceptable. Perhaps I got a bunk panel but after googling "dim XBR6" it seems like several people noticed the same thing I did.

I started doing more research and noticed that Amazon started carrying this television within the last week or two. Samsung must have caught on that they were losing sales due to their red color fetish as this panel is a beautiful dark shade of gray. Anyways, the XBR was returned and this panel replaced it. It's as clean crisp and clear as you could imagine from a non LED backlit panel. Its like night and day between this set and the Sony. The action is clear and crisp and the picture is just impressive. I highly recommend this panel, it is absolutely the clearest picture around without paying the huge premium for an LED set. You will not regret going with this TV. The only negative I would mention is that the panel is fairly reflective compared to the Sony. Definitely not an issue when the set is on but when turned off its definitely noticable.

I researched HD TVs for several months before finally deciding on the LN40B750, and I am very, very glad that I waited and got such a good television. Many factors went into this decision:

1. The TV is for my bedroom, so I didn't want one larger than 40".
- This requirement took the Samsung LED 240Hz TVs out of the running, since they only offer those in 46" and 55" at this time

2. I had gone to many, many retail stores to see the screens with my own eyes. I went to so many stores because one store may have the Sony set up to be superior while another might favor the Vizio, while yet a third may favor Samsung. I found the Samsung to have a very clear, crisp picture very comparable to the Sony, but with a lower price point. I also found the Samsung to have a better picture than the Visio. (I also preferred the layout of Samsung's remote over that of the Visio.)

3. I wanted a 1080P, 240Hz, 100K+:1 contrast ratio with lots of HDMI and component inputs.

The LN40B750 hit the money on all marks. It is a very pretty TV, with a shiny, easy-to-clean finish (it even comes with a micro-fiber cleaning cloth), and a gorgeous stand, if you don't want to drill holes in your wall. The 240Hz picture (as others have said) takes a little getting used to. I tuned into USA HD once I had the TV on the stand I bought and hooked it up to my FiOS box and started watching "U-571" in HD. Funny thing: it didn't look right. In fact, it looked as if someone was putting on a live production of the movie. Everything was so crisp and clear, and the movements were so smooth, the entire movie ended up looking as if it were live! Two days later, I visited my father who has an older Sony HD TV (60Hz) and he put his HDDVD copy of U-571 in for me to compare.
