LCD tv questions

PostBy: av8r On: Wed Dec 03, 2008 10:04 pm

So I'm looking half heartedly at LCD TVs. 42" is about the biggest I'd want. I went and looked at a used (7 months old) JVC tonight. Nice tv, but something odd. When watching a 4:3 broadcast the tv must be manually zoomed to fill the screen. Most of the channels we get on Time Warner's digital box are not HD and will be in the 4:3 format so this particular TV would need to be set as zoomed and of course if the analog signal isn't bad enough to begin with on an LCD, stretching it makes things even worse. Does anyone know if these TVs are supposed to scale the image automatically between 4:3 and 16:9??

So....as none of the stores have these TVs hooked up to anything other than HD there is no way to tell what the picture looks like with a standard signal. My opinion so far is that LCD tvs look like crap unless you have a HD signal coming into them. My CRTs look much better (to me) than any LCD I've seen thus far on a non HD signal. I left the stores completely disappointed in the image quality of these tvs.

I think all 16:9 TV's have the ability to "Zoom" a 4:3 picture to fill the whole screen. Usually it's done in 1 of 2 ways:

1. The picture is stretched & distorted to go from 4:3 to 16:9

or

2. A portion of the 4:3 picture is Zoomed in on & fills the 16:9 screen. No distortion but part of the picture is cut off


I don't like the distortion so I'll usually just leave it set to "Normal" which gives you a trfue 4:3 picture with black bands on either side.

Hi Def comes in properly (16:9) on all these sets, with a Hi Def picture source, of course.

So I spend $1400 for a 42" set, but have to either live with a stretched and degraded image or a 27" equivalent picture?

I'm not trying to be smart, but I can't figure out what the big draw to these TVs is...seems it's more about getting folks to spring for HD programming?

I hear you!! :lol:

Things are improving though..... Most shows are now available in Hi Def & sporting events are much more enjoyable to watch on a large screen. (I mainly watch News, Hardball, & CSPAN so it's really not a priority with me! :lol:

(2 years ago there was little to watch in Hi Def but skateboarding!! :mad: )

You mentioned most of your channels on cable are not HD. That seems odd, my Direct TV has something like 100 HD channels (and I don't have the movie package) and I thought TWC was the same. I don't even have non HD channels in my surfing anymore, once you get used to HD you never go back, at least that's how I feel.

I pay $70 a month for cable and get something like 10 HD channels. TWC is terrible.

I just got our new 46" LCD hooked up today. We have quite a few HD channels available, and the image quality is simply stunning. I just watched the Shawshank Redemption on HBO and couldn't get over how clear/sharp everything was. As you mentioned, the non-hd channels only fill part of the screen unless you "zoom in". I just leave at the 4:3 ratio rather than distort the image. One thing I found out, it is pointless to hook up a 1080p television without an HDMI cable. I tried mine with analog and s-video and was very disappointed with the image quality. One trip to Wal-Mart for some HDMI cables and I'm a happy camper. I also got an optical audio cable to run my receiver for surround sound, that works great as well.

Not here...there are a handful of channels that are HD 24/7

The guys at Circuit CIty said they get almost 50% returns on LCD sets. People get them home and can't believe how bad they look on SD channels. The guy at Sams had a similar story!

You've discovered Marketing 101. Store salespeople will give you the dumbest stare if you ask them to see the picture on analog settings, plus by using HD they typically make the sale no questions asked unless your in the know. The larger cable TV and satellite companies purposely taylor their tier packages to extract the largest profit possible. Also, most of the profit is made on the digital converters - what a crime. Our system, one of the smaller Mom&Pop outfits, give digital channels for as many TV in the house for no extra costs.

Go Direct TV then. They are having a good sale right now. I have subscribed for a year and have had no lost signal issues or down time. And I have read the cable companies also compress the signal more, which leaves a lower quality HD picture than DTV. If you are coming from TWC they will really work with you, get them to throw in something extra.

I have cable right now with about 8 TV's in the house. Only 2 are HiDef & the rest run just off the 75ohm cable wire for all non-digital stations.
Direct TV would not give me a clear answer but I was left to believe that every TV would need its own box...Is that right?

I don't have a 19:9 TV and I don't know if they send a falg over broadcast what the aspect is. If they do you'd want a device that intercepts the flag and adjust the signal accordingly, for 4:3 on 16:9 TV you want to have it pillar boxed. I'll explain why it works on DVD which might shed some light on what you need to do.

A DVD uses the same resolution video for both 16:9 and 4:3 for 16:9 it's called anamorphic. Note the round signs look like eggs:

When you author the DVD you set the flag as either 16:9 or 4:3. You'll set your DVD player for the type of TV you are viewing the video on. If for example it's a 16:9 video and you have set your DVD player to output to a 4:3 tv the DVD player adds black bars top and bottom so the aspect is correct:

Vice versa if its 4:3 video on a 16:9 TV, it will pillar box the video adding black bars to the right and left.

Broadcast is going to be the same way, there should be way to pillar box at least manually.

I had Direct TV five years ago when I also had Direct PC. Unless it's changed and I doubt it has you do need a receiver for each TV, unless you want to watch the same channel on each TV. Think of the box as a receiver with a video output. It can only tune one of the channels at at time. I had two receivers, the second box costing an additional $10 a month. I installed a complicated coax patching system that could direct the two receivers video to each of my four TV's. It was a pain especially since the remotes are IR and you had to be in the room where the receiver was. I canned the system when I got a DSL computer system. I've got basic cable service now. It sucks. Direct TV has much better video quality. I'm waiting for Verizon Fios. The basic infrastructure is being installed now. It will be two years before it get to me.
