Hi everybody!
Today I calibrated my Dell U2720Q monitor using DisplayCal and afterwards I did a verification and got the following measurement report – attached.Could you please advise what I could change in terms of settings so my “Measured vs. display profile whitepoint ΔE*00” result
is better? Everything else seems great.
I’m using Calibrite Display Pro HL to measure.
Thank you kindly in advance!

I think you will have to change the black point to get a more even gamma. Your top end is bright. You do have good blacks since they higher gamma and not a grey black. Grey black is adjusted with backlight my way. White point is off for many reasons. Red could have barely clipped at RGB 254. It does that on mine with the true 16 bit 1d lut to 256×256. Ive been wondering if a set white brightness instead of as measure would prevent that clip. Try target brightness to 100 and manualy adjust the brightness to 102 to 105 nits. It will sacrifice some contrast to .9/2 or .9/5 from what it could be. That clip is undectable and might not needed to worry about unless your like me and cant stand anything not 100 accurate even if eyes are 75% accurate. The iTcP is .4 delta e on the white point being being off which is below eye can see.
Gamma starts low numbers in the low end and goes up to 2.4 per spec. 2.4 in spec is not very bright at 100 nits. 2.4 is for HDR in my opinion. I choose a gamma with black relative and covers a lot of the 2.2 gamma with a low contrast screen like yours. Mine is 1000 contrast tv.
Many thanks for your detailed response, Ben!
My calibration speed was medium so next I’ll switch it to slow to get a better result.
As per your recommendation I will also:
– increase brightness to 102-105 nits (with target brightness of 100)
– will set Gamma 2.4 with black relative this time. I am choosing 2.4 gamma as I use my display for color grading video in a dimly lit room.Will come back with the new report once I’m done : )
Have a great day!
I expect the speed of light to a report. We do work at the speed of light on the screens. jokeing. Thanks for the day off.
Hi Ben! Attaching the new results – from what I can see – they are perfect! I also switched the correction to LCD PFS Phosphor WLED IPS, 94% P3 (Panasonic VVX17P051J00 in Lenovo P70) and that also seemed to help my result.
Thank you again for everything!
Also just in case for additional info – attaching a screenshot of my Profile self check E*76 report at the end of the calibration:
Much better RGB gamma tracking on 95 and 100%. It is perfect. The correction change was a good idea. CCMX is inferior to ccss.
Your welcome.
Hello everyone,
I’m new here and apologize for reopening this thread.
Unfortunately, I also need to calibrate the same monitor, but I don’t understand much about it.I use this configuration:
– Windows 11
– Xrite (i1 Display Pro)
– DisplayCal
– Decklink Mini monitor 4K
– Kramer C-HM/HM-10 HDMI Cable – 3.0mI followed various tutorials, and after calibrating, it came out with a disgusting 73% sRGB.
I created the 3D LUT and applied it to the reference monitor. The result: the colors were completely off and misinterpreted; the whites looked yellow, and everything else was magenta.
I don’t understand how to set the monitor; if I set it to RGB, it turns everything magenta. I don’t know how to set DisplayCal.Please, could you help me?
I’d be grateful.How does it look with a linear 1d lut? Hit the reset video card gamma table in Display Cal Profile loader. You do have nvidia driver set to not be reference mode? What mode is Windows in SDR or HDR? Automatic color management is off in windows display color management? Funny they call color management “color profile” in display settings in Windows 11. Sorry I would not know a thing about https://www.blackmagicdesign.com/products/decklink/techspecs/W-DLK-32 . That could be what is wrong. It does work but it does need to be setup right. It looks like a HDR playback like I had with Creative Labs DVD hardware decoder but that had analog VGA out to go to its VGA in with a short cable. DVD was decoded by the card and looked better than software video card dvd playback.
I realize it is the monitor. I am not sure which monitor connection or monitor has the magenta. They do that though when it is in a wrong color mode RGB or YCBCR. YCBCR is for video work. RGB is supported but I can not say if full RGB or limited RGB for your declink card.
I hope some one can help. I am just trying.
First of all, thank you for your reply.
The monitor is connected to the Blackmagic card, so it’s not controlled by the graphics card.
Out of curiosity, I tried connecting the monitor to the PC, and the magenta is the same when I set it to RGB.
I’ve already spoken to Blackmagic about another issue: the monitor loses signal in 4K. Unfortunately, I have no way to test whether the problem is the monitor or the card.Considering the monitor I have and the Resolve setting, how should I set displayCAL in the first and second windows (display & instrument | Calibration)?
Thank you very much, you’re very kind.

Your welcome.
CCMX > CCSS “if” you made it for yourself.
CCSS > CCMX if you downloaded both bc the CCMX is not portable.IMHO is better to explain to the newbies that “CCMX is not portable between different i1d3 units”, “you cannot use other people’s ccmx”.
Regarding the low sRGB coverage, everytime you see this, far bellow display’s spec, there is a hight chance that an sRGB simulation running somewhere.
Resolving these issues implies testing each step in chain: unplug your dell from decklink, plug it as regular monitor to GPU, make sure you are on OSD that is native or in your chosen colorspace preset.
If that matches what you’d expect, remove LUT3D from lutbox or Resolve, and re make LUT3D.Srgb emulation does explain the low srgb coverage. It could be the color control on the monitor. Factory reset the monitor to see if it behaves right. Then adjust the monitor RGB controls and visualy check for black level and white level crush.
RGB is wrong input format for your video card settings and the declink. decklink does 4k in 8bit or 10bit yuv 4:2:2 25hz . Check your graphic drivers for the video format.
