Official 2012 Sharp LC-XXLE640U/XXC6400U - Page 27

When I was at Best Buy, I got them to hook a laptop to the TV, set it to dot-by-dot and 1920x1080. Well, guess what, it is dot-by-dot displayed perfectly, except everything is shifted to the right by a couple of pixels (show a tiny thin black vertically line on the left) and the the screen is cropped off by a couple of pixels. Again, it's not obvious unless you are paying close attention and have your face right up staring at the screen. It is like this:

Dot-by-Dot
Displayed with no overscan/underscan
Every dot is matched to a pixel per computer output
Using X.Y, coordinate, the entire image is shifted by two pixels to the right (2,0).

It's is still dot by dot just everything is moved to the right by two pixels. Kind of weird, but after trying it at both Best Buy and Costco, and both LC-60LE600U and LC-70LE600U, it seems like it is by design to be like this.

Can someone confirm this? Again, you have to look extremely closely and only appears in dot-by-dot using true 1080p resolution with no over/underscan.

Hi everyone. I just switched from an older 720p hdtv to the 640U and found this forum very helpful - esp Z-Mad's calibration settings. Anyway, from testing out everything from cable, usb, netflix, ps3 etc, I have noticed a few things and am looking for feedback.

1. I have noticed selecting the menu option on the remote, when I have a channel on through my cable box, the channel typically changes to the first sd channel 0002. I have newer samsung dvr's as part of time warners signature home setup. Anyone notice this? I am guessing it is something goofy with crossed remote signals or something.

2. I believe I have it figured out with the AV mode where it saves your changes when you set them ie I set the game mode to Z-Mad's settings and they stick. Well then I noticed that with netflix, game mode is not an option so I set the User mode to the same settings so I can use those settings with netflix. What I found though is I cannot use those same settings to watch stuff through a usb source. I can pick User on usb but is not my saved settings(it says user-usb) and if you try to edit the settings through the menu, most are not available to change. It seems you are forced to use a preset mostly in usb. (It's not a huge issue for me as I have a dvd player that I always use for usb 2.0 playback so I can go that way and use game mode on that input - but it would be nice to have everything at the tv directly)

Do you have any pics of your calibrated set? I am considering the LE640U and forgoing 3D all together. Since I have to replace my HX929 I have been checking out my best options on a budget of between $1,000-1,200.

I have noticed that Netflix is not as good as through the xbox. The settings are displayed as they should be for 'user' mode but it seems a bit off. The lip sync is off a tad too where through the xbox it is fine.

Bill McNeal, looking at my set I don't see any break along the edge.

The settings are not transferable between modes, so what looks good in game mode might look completely off in another mode. I would suggest watching Netflix through your xbox where you can still run it in the game mode.

Perhaps there are some models with different parts/panels that cause the big change.

The connections are a Directv HD DVR hr24 connected via hdmi to a Sony str-dn1000 receiver and then a single hdmi to the tv. Is there any kind of adjustment to the tv? I can't find one and I can't find one on the receiver either.

Z-mad, I know what you mean. CNET's were in MOVIE mode but I built my settings off USER mode. Using your settings In my GAME mode just made my set all washed out in color. No offense just saying the settings could be all over place depending on one's starting point. I may get the Disney WOW disc just so I have a reference because so far just going by eye.

As stated before by many (including myself), the settings certainly do not translate the same from set to set. Some sets will accept them quite well, some will not. As with anything, these TV's are manufactured in different batches and there are some differences between them. These variances are normal, so it is a bit of a game of chance. I posted my settings for anyone to try, certainly without guarantees how well they will translate onto each set. Also, there is always a matter of personal preferences too of course. Some people like the picture as bright as possible, kind of like they see it in the stores, or may have some other preferences. My settings are based on setting the contrast, brightness and colors in a way proper calibration suggests, so no details are lost in whites or blacks, the colors are accurate and natural looking, and overall picture has a good contrast and "pops". Some have reported washed out looking picture with these settings (which certainly isn't the case o my own set), some have reported fantastic picture. It will certainly depend on the set and some preferences too. Whichever settings work for you and on your set, enjoying your TV is what counts Cheers...

Perhaps if we dig a little deeper into the serial numbers/parts, we can find some sort of trend in the feedback.

Also how did you come up with them? Did you use a calibration disc ilke Disney WOW, had an ISF professional, or just eyeballed it with each individual setting?
