Thanks Sascha,

Well it does look a bit milky, so that’s a good sign. And yes it is between 100 and 700… again good sign.

This does raise a question I have had though. I think I am correct when I say that 100% white on the IRE scale is 700.

But the waveform monitor on Resolve goes up to 1023. I can raise the gain on the image all the way up to 1023 without the image losing detail or “overexposing”… this confuses me a bit. It seems to me if I go over 700 I should be whiting out. (The image does not look nice over 700 though – it has a “too contrasty” look to it)

Or is happening because I am using LOG and just don’t understand how to color correct in the LOG world yet? 🙂

Christoper,

I had been wondering if my Quadro was being used by Resolve. Under “About DaVinci Resolve” is says:

Version 8.0 1 GPU

Does that mean it is using the Quadro?

If there was only 1 graphics card in my computer (say just the GT 120) would it say 0 GPU?

Jan, I’m only a small step ahead of you here. I just put a Quatro 4000 in my Mac to set up Resolve.

A few things that might help:

– Blackmagic has a configuration guide on their website separate from the regular manual. It’s very useful.

– The 1 slot is on the bottom and the 4 is the one on the top.

– I “downgraded” my GUI card from a Radeon 4870 to a GT 120 because the 4870 used 2 of the power connectors leaving none for the Quatro 4000. The GT is also like the Quatro using only 1 slot width. This gives you 1 more opening for the HDMI in/out connectors for the Decklink. Eventually I will replace the GT 120 with another Quatro. The GT 120 is under $150.

– If your monitor does not have HDMI or SDI you may need a Blackmagic HDLink Pro as an SDI to Display Port adapter for your monitor. They are about $500 dollars and there does not seem to be any other option – if there is another option someone please let me know as I have not bought the HDLink yet 🙂

I’d like to know this too.

From Alexis Hurkman’s Color Correction Handbook:

2.5 This is the gamma for both SD and HD video displays as defined by the Rec. 709 standard. 2.5 is the gamma standard you should adhere to when you select a display for color correction work.

2.2 This is the default gamma setting used by all versions of Windows and Mac OS X starting with version 10.6 “Snow Leopard” and above

Thanks Kevin for the answers.

It was between the Dream Color and the NEC back when I was shopping around. I ended up with the NEC because it was half the price, but in hindsight I wish I had gone with the Dreamcolor.

I finally got the settings right and can see a picture on the TV! So I can now at least start to learn the software.

The next step is to buy an HDLink (the displayport version) when I want to hook up to me NEC.

So much to learn……

At the moment I’m simply trying to get a picture with the HDMI input on my TV (I have a color correct monitor but need an HDLink I’m think).

I figure I should be able to set up everything with the HDMI TV – not color correct of course – just see everything working.

I have a NEC PA241w. It has DVI or Display Port (not mini) as the main inputs. It is a color correct monitor capable of 10 bit – it’s considered a “pro” monitor, but I’m not sure why it’s lacking in SDI or HDMI.

By the way – what is the cheapest Color Reference monitor with SDI inputs?

[David Smith]

This whole concept of using the Capture card to connect to my monitor is new to me.

I still can’t get a picture on my monitor using any software – although Video Camera > Decklink SDI> Media Express> Decklink HDMI > TV HDMI works fine.

1) Should it be able to see my monitor as a display in my Mac Pro settings?

2) If not how will I be able to calibrate my monitor now?

[David Smith]

I just tried it. Same message. “unable to locate the following external devices”

I think Resolve 8 must be and update to 7. So 7 must be installed first.

Each time I install 7 or 8 there is a firmware update too, which I think has messed something up.

[David Smith]

I updated to Resolve 8 and now I can’t connect to the Decklink at all when I start up FCP7…. hmmmm….

But when you said it must say “DECKLINK” in the name I’m assuming you meant “Blackmagic”?

Or maybe that is my problem?

[David Smith]

Thanks Kevin,

That clears things up a lot for me. So I need 3 monitors (including the grading display).

I discovered I need a new monitor anyway since Resolve wont work on my 1680×1050.
