Sharp Elite 70" LCD (PRO70X5FD)

[Anonymous]

Last Friday I worked on a new Sharp Elite 70″ LCD (PRO70X5FD).

Results:
I got things dialed in pretty well (report attached) minus some things where the CMS system didn’t seem to be working. Red and blue didn’t seem respond at all and green took the entire range before it came in. Secondaries responded well to HUE but not saturation. Level adjustments worked well for all colors that I needed to use it on although blue was really jumpy.

According to the Sharp calibration guide posted for the TV (SM section of thxvideotech.com) it states not to touch the main Color and Tint settings and only to use the CMS system. I followed those instructions.

The issue I was left with was that while most HD material like HBO HD, Discovery HD and BluRay looked pretty good. But on all the talk shows, news casts, ESPN and such everyone had a lobster skin sunburn. This was part of the reason that they had the calibration done in the first place. It was improved somewhat by lowering the RED Saturation but was still annoying. I coached the client a little bit regarding source quality issues but was hoping that you might have some further advice for me regarding this issue.

The settings were all zeroed when I started. Post calibration settings are on the bottom of the report. The set is in Standard Mode and cool or cold or whatever it was called on this set. All automatic processing things are off except Noise Reduction and 120Hz are set to low.

Thanks,
Jon

the gamma bump on 90-100% is showing that the contrast is too high.

This display does have issues (others have reported them too). Waiting on Sharp for a firmware update/

Anybody else with suggestions ?

[Anonymous]

Is it likely or unlikely that I could massage contrast without effecting the greyscale and CMS accuracy? Or is dropping this going to certainly effect the greyscale as it’s changing the dynamic range?

Do 10 point grayscale and then work backward down … but the 10 points may not line up with 100/90/80/70 and so forth …point 9 affects 80 … stuff like that … so keep and eye on it.

The TVs change over the years. If touching color and tint before cms helps things … go play with it.

Yea I did notice that. I went back and forth a bit with the neighboring data points until I felt like I was splitting hairs.

I haven’t done a Sharp Elite yet, but I have done a lot of Sharp LED LCDs lately. The red tint I have found has to be set opposite of what the measurements suggest to get good flesh tones. Measurements suggest red tint should be pulled toward magenta (negative red hue), but looking at program material necessitates a slight positive red hue number (usually in the +3 to +8 range). I see your red hue is -13, that’s why I bring this up.
Again, I’m not sure if it’s exactly the same on the Elite as it is on Sharp’s other lower lines, but it would be worth looking in to. Maybe that’s why the people on some sources still looked lobster red.

hi
I did a 70″ on Friday. I used the 2 point gray scale and then did CMS. I did not touch the red CMS controls. It looked very good when I was finished, perhaps just a touch too much magenta in the flesh tones but I was happy (and so was the client).

Just an important safety tip…

I have been making it a habit of performing my calibrations with 10% sized windows. For plasma panels I find this works out very well. However, I did notice an anomaly with the Elites, as well as other Sharp LCD’s. When measuring color windows (10% size), I noticed that when the blue window is displayed the entire screen gets much dimmer. It’s like the local dimming is active even though it is turned off. This only happens with the color blue. When I switched to a 25% size window this phenomenon didn’t happen.

A reminder that we should always check to see how a display behaves with window as well as full field patterns.

I haven’t seen this discussed anywhere so I thought I’d post a heads up.

-Did you at least adjust red luminance or did you avoid all three axes?

[Gregg Loewen]

i dont remember. I would have adjusted the red luminance using the global color control.

Red brightness tends to be fine, but the sat and the hue controls make people look really really bad. Purple.

I’m going to be doing my first Elite next week. Anybody using CalMAN’s Sharp Elite Direct Display Control feature? Is it worth using for calibrations or will results be the same as using the Sharp remote control to change settings.

There were some mentions in this thread of lobster-like fleshtones being an issue… has this improved since those posts (newer firmware helped maybe?)?

Any other tips or procedural preferences that help with calibrating these?

[Anonymous]

Same results with the ISF activated or you just do it in movie mode. The CMS works better now … but watch out for the red hue and sat just the same.

Doug,

I recommend using ControlCal for the Elites, calibrating ISF Day and Night modes. You can achieve good results (just watch that CMS) and it will make your life much easier. I DO NOT recommend using the remote control method for calibrating the ISF modes. One wrong button push and you will lose all of your work!

[Anonymous]

Why ControlCal? Does the direct connection (DDC) option in CalMAN not work?

[Anonymous]

The DDC works fine.

Just like using chromapure does not imply that calman does not work.
