Back in the market again and looking for a decent 55" LCD. A couple of years ago edge vs full array backlighting was a big deal. Common complaints about edge-lit displays due to lack of uniformity in the backlighting, cloudiness, etc. But I know manufacturers were working on addressing these concerns with better diffusers, etc.

Anyway what's the current state of things wrt to LED backlighting techniques? Is full-array backlighting still the more desirable technology? Have the issues with edge-lit backlighting been mostly resolved? Can anyone recommend any decent 55" LCD's in the sub-$1200 price range?

Any advice welcome...

It's still a big issue.. Manufacturers have decided to keep edge lighting alive on all but their top of the line models.

You here are no shortcuts., you will have to pay your dues by studying the threads on all types of TV's and the potential problems they may pose..

One unsolicited piece of advice.. DON'T!

Just get the TV you like in a showroom, turn it on and live happily ever after. The more you go looking for trouble in your TV, the more likely you are to find a deal breaking one.

Samsung EH6000, ES6500or the LG lineup.. Just pick one and run with it.. Never come back to the forum smile.gif

Insert pithy comment here

But none of those are IPS panels, are they? What's the point of a full array if it comes with a panel worse than lower end models?

Don't get to hung up IPS panels, they aren't the end all...good color accuracy and "slightly" better viewing angles but black levels aren't near as good.

Is there a non IPS panel with good vertical viewing angles then? In my situation I need a TV (47~50, not getting plasma so it's not worth discussing) that will be on a shelf that will make it so the tv stand is the same height as your head when sitting on the couch. We watch TV from the floor mostly looking up at it on a 45 degree angle from about 6 feet away. I need something that wont wash out when looking at it from a not straight ahead view.

I haven't seen an LCD display yet that doesn't quickly wash out when vertical viewing angles become slightly less than ideal...that being said, the ability to tilt it usually overcomes those issues.

Well I followed the advice above and just picked out a set that looked good at the store. Took home a Sharp 60LE640U. I was initially wowed by the PQ but then started noticing intermittent judder in scenes with motion. Turned off all the motion smoothing/film mode options but found there's still some processing being done to smooth out motion that cannot be disabled. My 2-year old Insignia LCD didn't have this issue; are all the manufacturers forcing image smoothing to be active now? I'm disappointed as I was honestly happier with my old Insignia compared to this new Sharp despite it's inferior contrast. My old Insignia didn't have any audio lag either; this new Sharp suffers from intermittent voice lag no matter what settings I use.

Does anybody just make a basic LCD screen anymore? I just want an unaltered image without post-processing.

I haven't seen any TV for which you can adjust the vertical angle unless it's wall mounted on an adjustable bracket. TVs that come with the regular pedestal/stand and sit on a table or entertainment center of some sort may be adjustable from side to side but not up and down.

if you use game mode, that'll be as close as you can get to disabling all motion processing. I found however with the 8470, that game mode locks you out of some other settings, like color gamut which is set to expanded, and you can't calibrate colors or grayscale very well.

But it's a tradeoff.
