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
Go back to list of all features

Why LCD?

LCD displays deliver increasingly higher contrast ratios along with bright, crystal-clear images that look great in a variety of lighting conditions. They're available in sizes that fit any space, at prices that meet any budget. Many LCD HDTVs also have new features that can significantly reduce power consumption. So whether you enjoy movies, sports or video games, there's an LCD HDTV just right for you.

My first impressions...

For the past 2 months I've been researching and looking for a 40-42", and there were products from Sony, Samsung and Panasonic that were solid options. I was all set for a Panasonic plasma but passed by the 42SL90 LED/LCD on my way to the salesguy. I pulled up short and stared... and stared... and stared. That SL90 is a great looking TV but was priced above my budget. Salesguy suggested I take a peek at the SL80... I was still wowed! Spent an hour Saturday night comparing this set to 3 others watching HD on CBS and tweaking the screens. I needed to do some more research before making a decision.

Didn't find a lot online about the SL80, so went back on Sunday for another hour looking at the NFL pregame show, and some of the game, on broadcast HD. This time the Panasonic plasma and the SL80 were the finalists. Both screens had excellent picture quality, but it seems I'm an LCD kind of guy; I prefer my screens on the bright side. So I got the 42SL80.

At home, the picture quality was simply outstanding, the sound is more than adequate, and Comcast HD never looked so clean. Standard definition receives a thumbs up as well. Connecting my portable hard drive to the USB port on the TV, I was pleasantly surprised to discover that I could play my DVDs I had copied on to the drive. Not just pictures and music, but movies as well! A big plus in my book. Last night I viewed files from a TS folder, and will try other formats tonight.

Alas, it's not all smiles and sunshine... a lip sync issue emerged later on at night. The sound seemed to lag behind the video. This issue was also reported with their LH90 sets when viewing content through a set top box, and a firmware fix was quickly issued.

Great Picture, I love the amount of customization available to change picture and sound settings. Set is very stylish and features simple easy to understand menus. The only real drawback of this set is that the screen is REALLY reflective and if there is any light behind the viewer (i.e. window in daytime, even with blinds drawn) it's like looking in a mirror.

Amazons shipping partner Pilot is pretty poor. It took 8 days to ship from PA to CA, and they gave me a choice of several 4 hour windows for delivery but all in the middle of day on weekdays. My only other option was to drive 60 miles each way to pick up the set myself.

I love the picture and build quality but have to agree with the other review that the glass front makes this TV too reflective - everything is there! The product shots really don't give you a good impression of this. So, this TV would work best in a media room where you can really cut out unwanted light. My plan is to fix with really light frosting film - if I can find something appropriate will post a follow up.

HD content looks fantastic. Blacks are very black.

I had lip sync issues initially with my Charter Motorola cable box but setting it to 1080i (instead of 720p) has fixed this.

Only audio output is optical. HDMI audio is switched to the optical output - so greatly reduces the number of cables you need.

LG need to post the manual on their web site.

Received the product seven days as promised. No problem with assembly. One problem; sound lags picture as many reviewed prior. Called customer services within 24 hours of receipt and promised service between 8:00 and 12:00, noon tomorrow. Very happy with the service thus far. It was indicated that I should have an update applied tomorrow that should correct the audio/vidio problem. This is the reason for the 4 1/2 construction quality.

Technician arrived approximately 24 hours from reporting my problem. He applied a program patch to the TV using the USB port. The fix was applied in about five-minutes. Perfect picture/sound. I would rate the TV five stars now.

I've only had my set a couple of days. It arrived on time. I like the picture and the sound.I have a few problems with it but am hoping most of them will be resolved soon.
One big problem for me is that there is no analog audio output, only an Optical,which I had never heard of before. I'm a senior and depend on my wireless headphones and have only found out by trial and error that I will have to get optical headphones or an adapter for optical to analog. When I e-mailed the LG company, I was told it was in the specifications. There are several pages in Amazon'n description and maybe it is there but it must be pretty well hidden. In a 1100$ plus machine one would not expect the absence of such a basic feature. One would at least expect a warning that it is not there.
The channels don't change as quickly as they did on my old RCA
The on screen menus are somewhat complicated and difficult but I guess they will be easier with experience.
I hate having only a CD manual but the company has agreed to send me a printed one I'm hoping I made the right decision in buying this set and may write another report later after using it longer.

This TV has a super clear picture with blueray and good with reg dvd, I was watching Terminator Salvation and the picture was the best ive seen ever better with trumotion on low, some reason with Terminator on blueray the tru motion was really good other movies it might look unnatural. 240hz for under a $1000, great deal. At first the trumotion was kinda weird looking once you get use to it, it looks great especially with gaming with xbox360 the graphics look more smooth like gaming with a hi end gamer computer. The blacks are excellent and it does make a difference cause dark blacks makes your picture look more clear and crisp, picture is bright so much better than my samsung DLP and sony xbr 6 new tech way better. If anyone has ever had the problem with older lcds that when you play games the picture is very dim and you have to turn up the brightness the LGsl80 has no problem hooked it up and good to go. People always complain about the sound being horrible but to me the sound is great for speaker that are small and not even half way the volume is loud enough full volume would be too loud. Of corse your not going to get surround sound with bass. About the lip sync problem none maybe you need HDMI 1.3 not sure though but i have no problems at all. Also the TV is super thin.
