So I got a Display2 last night, and am working on calibrating my HD70. I am using HCFR, pointing the probe at the screen (at an angle) and using Getgray

Here's what I've gotten so far... BC and TV are both off, color temp 1.

Can someone make some useful suggestions/comments on these? What would my next step to try and make this better? It would seem that I am stuck with that green oversaturation (proper term?)

Thanks

Hi mpotka,

There is a thread devoted to HCFR results here (http://www.avsforum.com/avs-vb/showthread.php?t=786966) for posting future results. A quick glance looks like you might be running out of red at the upper end so try backing rgain down a bit and rebalancing. As far as color calibration it depends on what controls your FP has. If it only has color/tint you will not be able to decrease primary saturation. Take at look at this (http://www.avsforum.com/avs-vb/showthread.php?t=852536)
thread for color calibration.

cheers

Hey--thanks for the response. I did figure that I was running out of red on the top end, but I wasn't sure what I should do about it. If I remember right, when I decrease red gain the whole line ends up below the spectrum. Do I drop the red line where I can get it flat, and then bring the green and blue down right on top of it? That would keep the grayscale tracking evenly, but at the wrong temperature correct? Which is worse?

I have read the sticky on color calibration and the faq--that was a tremendous help for getting me as far as I am. I kind of figured I was SOL on the colors where they were, but I wanted to ask anyway

You have to turn your contrast way way down - not just your red gain. What is now 60IRE brightness becomes the 100IRE brightness. You can do it with reducing RGB gain but easier just to pull down contrast.

The curves you have are resulting from internal RGB gamma tracking curves inside the PJ - it is designed that way to do that - and you do not have the PWL RGB gamma curve correction to fix it (other than a $4K video processor ...)

You will not like your brightness/contrast specs when finished (think several years old LCD) - but other than that the PJ tracks D65 very well and REC709 OK.....do not use 1931 CIE to judge green specifications - use 1976 CIE.

That's the correct thing to do, you'll end up back at the right color temperature.

yep, unless you want to get an external VP or use an HTPC.

well, I might consider using my HTPC for HDDVD and Blueray if it wasn't such a hassle still... one of these days we might have a bit better selection on software

Kraz--concerning the contrast way down, are you talking about my master contrast?

How do I know what to turn this down to? Does that mean I will not be using the standard patterns for setting brightness/contrast?

Hows this look then?

Only thing I am not sure about still is that my gamma at 80ire says 2.99?

Correct - you turn it down while you are measuring 100% white after doing your greyscale getting it best you could. The standard contrast pattern has you looking for white clipping - you are looking for white color temp to start shifting - then back off.

That is better - but I bet you can get the bump out at mid grey with more grayscale tune (bias/gain interact there) - and you still have the red gamma bump at 90IRE - turn contrast down more. Sacrifice the near blacks for the greys.

I presume you have your auto lamp/iris and TV gimmicks turned off - as that can wack out gamma. Yes there goes more spec contrast....

Well here is what I've gotten to with more playing. The Red just doesn't want to go flat... this seems fairly close to me being a rookie and I'm just hoping my eyes get used to seeing the "right" colors for awhile (even if they are a little off)

yeah I have all the xtra crap turned off on the HD70. Thanks again for input
