HP Dreamcolor Gamma setting?

[Andrew Smith]

After having it professional calibrated along with my plasma some small adjustments were made to my Dreamcolor to get it as close to rec.709 as possible – here are my settings now:

rec.709 color space
6800K not 6500 9apparently was a little too red i am told)
120 brightness
black level 128

One thing we do notice now though is that the grey pluge coming from fcp color bars is VERY noticeable on the plasma while on the LCD Dreamcolor it is barely visible – I was told by the calibrator that that is ok and that he probed both to be rec. 709 as close as possible.

fingers crossed that we invested wisely in the gear and the right calibration expert.

A bit late now, but you can copy all settings to ‘user7″ and then have control of gamma from there.

Last night I was at the preimere of a feature i graded using my Dreamcolor, and the projection was spot on, tracked the colors and gamma really, really well.. what i graded showed up on the screen.

That always makes me happy!

what were all of your settings just out of curiosity?

How were you sure it was rec. 709 gamma 2.2 etc?

thanks forth response!

I’m not front of my machine today… so from memory…
open OSD
select color space
select 709
write down everything
step back
select user7
input the noted settings
step back
toggle between user7 & rec709 to confirm that all is identical
select user7
set gamma to 2.2
step back
run the callibration software

this is what i have in my “user7”, but i normaly run in 709 or P3 depending on the project, for web deliverables i will do a QC pass with user7 tho

“run the calibration software” can you explain? I dont have the little probe they sell for the dreamcolor if that is what you mean?

thank you for the response!

Yuppers, the probe and matching software, i keep it on the PC side of my dual boot MacBookPro, and hook that up to the Dreamcolor every Monday morning as a habit… no bookings until past 10:30am on Monday’s

Ta,

I cant help but wonder now about the fact that Resolve is a YUV based grading app as opposed to Color which is RGB – when using the Dreamcolor which is RGB progressive i believe how does this effect things?

I am using the Dreamcolor which is getting a DisplayPort signal from the HDlink3D which is receiving SDI from my Decklink Extreme 3D – now that its been probed along with the Panny Plasma is there a flaw in my setup?

any info would be great – especially from an BMD peeps who might read this in that the Dreamcolor is a widely used monitoring solution.

cheers
