Green / Yellow tint on LCD?

I can't seem to find the thread where someone had the same issue.

I immediately noticed the same greenish / yellowish tint on my LCD panel. Looking at a beige wall, it looks nice and neutral on the EVF and greenish on the LCD. Is this normal?
 
If you look at the bars on the LCD you can see that yellow has a slightly different colour than what you'll see in the EVF.

The bars look perfect on my AF100 LCD. Is it possible the bars and the image from the sensor or taking different paths to the LCD and the path the image from the sensor takes gives it a slight green tint? If that is the case then it's possible for the bars to look perfect and everything else not. I'll have to test that out when I have time to use my camera.

EDIT: I've since bought a TV Logic 5.6" LCD and the AF100 LCD is definitely off a lot. BIG difference. http://www.dvxuser.com/V6/showthread.php?233929-AF100-LCD-screen&p=2230087&viewfull=1#post2230087

If the bars are correct, I don't see how your images can be off unless you are viewing under uncontrolled or mixed lighting. There are certain surfaces, paints, fabrics, etc., which are very difficult for video systems to reproduce, (as the infamous "Barney purple") so you might try shooting something like a human face, which the camera should do well, and make sure you have a good standard light source.

Of course you could have broken camera! Hope not.

Good shooting and best regards,

I hate to say this, but I have 2 Af-100s and I am experiencing the green tint on the lcds as well. The evf looks great and matched really well to the recorded image, but the lcd is greenish. Its not as noticeable under some lighting situations, like outdoors, but in the studio...ick.

You are saying the synthetic BARS are accurate in both monitors but your photo image isnt.

From my post, #4, above: "Is it possible the bars and the image from the sensor or taking different paths to the LCD and the path the image from the sensor takes gives it a slight green tint? If that is the case then it's possible for the bars to look perfect and everything else not."

It's the only way I can think of to explain it.

Well, only you can judge how much green you have. My question would be -- would a normal and reasonable person, with no prompting, look at your LCD and say "holy cow, that's green"? If so, you may have a problem. I've had the AF100 in front of dozens of folks, and nobody has ever yet said that the LCD is green. I think there's a general acknowledgement that there might be a minor green tint in the LCD, but from my experience with several of these dating back to September and IBC, plus the Osaka group, plus "Verse", plus attending an open house at a dealer here and seeing dozens of people coming in and checking it out -- nobody has ever said "why is this LCD green?" Nobody. Not once.

I think it's a case of "if you pixel-peep it, you might see a little bit of green that nobody would ever be likely to notice". And if that's the case, then sure, that's normal. If yours deviates substantially from that description, to where you're seeing a big green shift, then you should probably have it looked at or compare it against someone else's at least.
 
I've had 3 gigs with my AF100, and have noticed the greenish tint. I have to say that in the shooting conditions where I did not have the field monitor to use as reference, was pretty run and gun, and was in mixed lighting, I was never quite certain what I was really getting in terms of color balance. It did not even dawn on me at the time to use the EVF to double check what I was getting. So it was a bit of a problem, but not without remedy. In the end, the recorded colors were alright, and looked better than what I had seen. But I would say that having the color veer off to that extent is something I hope finds a correction or user adjustment in a future firmware revision.
 
It's funny, our AF100 LCD's look very similar to a BT-LH1700--same green bias. This has always driven me nuts, but the 1700 is as close to the on-set standard monitor that exists at this point. They do not match any other monitors we own, so it's got to be some kind of Panasonic thing. I much prefer our TV Logic and Flanders Scientific monitor colorimetry.

It's harder to see the AF100 LCD bias with color bars vs. a neutral flat field of white or gray, and it's certainly evident with flesh tones. The fact that the LCD looks different than the EVF makes it clear that something's not right in color land--it's not pixel peeping, it's pretty obvious.
 
there must be some varying degree of green cast amongst units then because I see only the tiniest differences in color when compared to my calibrated broadcast monitor. i was actually kind of astonished how close it was. far from something anyone could suss out without having a calibrated monitor to compare it against. it's actually my lilliput field monitor that is way off.
 
I compared mine to my DP6 and the EVF and I thought the color rendition was the same. Strange. Must be some variation in the panels then.
