post #1711 of 3948
My 82740 is being delivered tomorrow and the likely high temperature here in Maine is about 29 degrees Farenheit. I think I read somewhere that it is not a good idea to turn the tv on in these circumstances and to instead wait til the tv gets to room temperature. (Of course I suppose I could open all the windows in my room and then it would be at room temperature immediately. )

Can anyone confirm this? If so, then I will just make sure there is no visible damage to the tv and worry about actual performance via Mits if necessary.

The reasoning is that coming from cold to warm will cause condensation that may fry the TV.

If it's part of the delivery to turn the TV on to verify that it works, I would go ahead and turn it on and if it fries, then reject it and get a new one. If it doesn't fry, then you can turn it right back off and let the temp normalize.

It's really up to you. It was part of my delivery to check, so I turned it on right away and then turned it off to hook all the other equipment up and put it on it's stand, etc. When I turned it back on about 20 minutes later, I didn't have any problems.

Thanks for confirming my concern....though I think I will likely not turn it on til it warms up.

Yes, my 82740 was delivered back in December on probably the coldest day of 2011. I waited an hour before turning it on just to make sure it had reached room temperature. The delivery guys told me not to turn it on because it was so cold and snowy when they delivered it.

No one should think they are an answer to anything. These setting terribly compress the dynamic range to almost nothing, they do not correct, grayscale, the gamma setting is way to low, and there is no adjustment of color gamut. These might as well have been throwing darts.

The biggest thing I see wrong are contrast and gamma. The contrast should at least be in the 50's and the gamma should be at 2.2. Beyond that I have no problem with folks leaving the gray scale and color controls at default when they don't have the proper calibration equipment to do it. I've seen people post some really crazy settings they came up with on their own and couldn't even be remotely right. At least this person kept it modest.

The person that isf calibrated my 82840 told me that he never has had a set from the factory with the proper color temp.

I concur, but from the factory is still better than an uneducated guess. That's all I was trying to say.

So I pulled the trigger today and bought the wd-73740. After contacting the online dealer and them telling me that they would be adding taxes it was more in my price budget to get the 73 instead of the 82. I am not disappointed! This tv is huge, and it only seems bigger in my living room. Now I think that the 82 would probably have been too big (if there is such a thing ) Thanks to everyone for all their help pre purchase and if anyone has any helpful hints about these sets I am all ears.

After discussing my stand problem with friend, we came up with an idea to cut out about 8 1/2" (my center channel speaker depth) of the top middle support. Looked at the attached picture and let me know guys what you think. So far easiest fix and it shouldn't be a problem as a most of the TV's weight is in the back.

After spending countless hours on this thread, I decided to buy the WD-82740 on Amazon via Paul's TV since the price is really low. My viewing distance is 10 ft and I was debating myself between the 73" and 82"; however, 82" is cheaper than 73" and I've made my choice. I currently have Sony 60" KDS-60A2000 with a new optical engine from Sony 6 months ago and this is a big jump.

Do you guys think 82" is an ideal viewing distance at 10 ft? I have Panasonic blu-ray and Uverse HD receiver, I rarely watched SD channels anymore.
post #1721 of 3948
8.2 ft is ideal for watching movies (THX home theater recommendation: screen size x 1.2) but 10 will be fine for daily watching, especially how low quality most HD content is still.
post #1722 of 3948
gogo, that will work well. That tiny amount of weight on the speaker's housing won't do it any harm.

Sure will look sharp. I was serious about having used a piece of cardboard, folded into a large triangular tube, to sit the speaker atop of the set. But yours will look better!

Viewing distance is very much a matter of personal preference. Some people watch the 82" set from 14' or 15' away, and enjoy the experience, and some sit very close and like that. A lot probably depends on your room size, furniture arrangements, and what you are used to. But, if your room has some flexibility, you can experiment to find out what you like best.

There is a THX standard which was originally intended for the design of movie theater seating, and which also applies to home theaters and TV's. If you like to sit in approximately (exactly in some movie theaters) the center row, you will have a 40 degree wide field of vision. That is the average width to be completely immersed in the screen and still be able to comfortably see all of the action at the edges of the screen. It is based on average peripheral vision. To duplicate this experience at home, you would take the diagonal measurement of your screen times 1.2 which is 98". So, if you have typical peripheral vision and like to sit in the middle of a movie theater, you would duplicate that experience at home by sitting about 8' from an 82" screen. If you like to sit a little closer than the center of the theater, you may be comfortable moving in a little from 8'2", and vice versa. Again, a lot depends on what you are watching (obviously, HD works better the closer you get compared to SD), your furniture arrangements, and your own viewing preferences. Wikipedia has an excellent article on recommended THX viewing distances if you want to check it out.

I would put supports on either side of the speaker. Not only would it look better, but it would keep the top from bowing.

The very low contrast setting especially means there is no dynamic range, and the gamma setting means washed out. This has to be a terribly blah looking set.

The other setting sure you have to have a meter and software. I just did not want any other users to think these settings the OP was using were an answer to anything.

You could put a spacer between the top of the speaker and under the shelf below the tv to provide a similar load path before the cut...

These comments make me feel like I'm really missing out on something. Yesterday, I took the earlier advice, reset everything - switched back to "Natural", "Low", and "0 Sharpening". Picture looks nice. Naive question, is there still a significant improvement in PQ to be had with further calibration?
post #1730 of 3948
My 82740 arrived today. Since it was going to the second floor the delivery company arranged for two people to deliver it...and they actually came in two separate large trucks...the neighbors must have thought we were moving!! It took a great deal of effort to get the set to the 2nd floor since we have a switch back staircase and the landing is not wide enough to allow the tv to be simply carried horizontally around the railing. So they had no choice but to stand it on it's end and slide it to get it to where they could take it up the second set of steps.

Given the cold weather I waited a couple of hours to turn the set on and then I simply connected my cable box via the HDMI connection. And as most others have said, the picture is really almost overwhelming....very pleased. I have not yet started to mess around with any changes in the settings other than to make sure it is set for home rather than retail.

The one issue I have noticed is that there is definitely an audio sync problem with dialogue. Since my prior tv (a Mits WS65709) utilized component video, this is the first time I have used HDMI with the cable box. So I am not certain whether this is a cable box or tv issue. Eventually I plan to attach a separate audio system...but for now I would appreciate any advice on what might be causing the sync issues as well as any ideas on how to cure it.

Thanks

Can you bypass the cable box and go coax straight to the back of the TV to help isolate whether it is an issue w/ the TV, signal coming in or the cable box itself?

Depending on how that test fairs - I'd go coax from the cable box to the TV (or some other non-HDMI connection) to further identify. Again, just trying to narrow the source.

+ 1, Turning a cold set on for 30 seconds or less will cause "0" harm, we have all of our clients power on at point of delivery.

I had the same issue with my Sharp Aquos and FiOS DVR in my bedroom. After swapping out the HDMI cable and then the DVR to a newer model per another forum, the issue was resolved. Component connections didn't exhibit this issue.

Please clarify/confirm: even a very cold set, like 30 degrees? Thanks.
post #1736 of 3948
Thanks for the various comments/suggestions regarding the audio sync issue. I will be working on the problem over the next several days (well I hope it won't actually take that long to evaluate/resolve) when I get some spare time. I'll report back with the results.

This is something I like about newer technology. If you have it try setting some delay settings (i.e. video/audio sync).

I'm watching it now (DVR'd it) and the picture is perfect and tack sharp. I have the 92" (92840). Just got it last Saturday so I haven't messed with it much. To be honest, the picture looks perfect to me. Here are my settings... please don't bash me! Give them a try.

Pic Mode - Brilliant
Contrast - 63
Brightness, Color & Tint - 31
Sharpness - 0
Color Temp - High
Video Noise - Off
"Energy" is set to bright
post #1740 of 3948
Thanks for the reply! And thanks for posting your settings. About how far away are you watching from?

Also, I find the show has a lot of compression artifacts in it (separate from the artifacts I mentioned). Do you see the compression blocks a lot? Maybe you're getting a better signal than me. (I'm on HD Cable) I'm asking because you surprised me with perfect and tack sharp. Some of the commercials were better quality than the show here!
