HOW TO Calibrate BenQ Hardware Calibrated Displays with Calman and should you?

[@dominey]

Out of curiosity, does hardware calibration with Calman write an ICC profile to the operating system like PME does? Or is calibrating with Calman a “pure” hardware calibration not involving color management in the OS? I’ve asked the same question to BenQ but haven’t received an answer (yet).

[@ArtIsRight]

Yes Calman does write an icc profile. There's really no pure calibration per say with computers, every single calibration to be accurate it must take into account the OS and drivers, because all of these variable changes the GPU output signal. So technically this is as "pure" as it gets, either that or "pure" is just fictional ;) Nothing will by pass the computer software and drivers at least on the consumer end. You can get an advanced spectrophotometer that cost $10k plus with a pattern generator that add more cost and calibrate the display then but you won't necessary be able to access the 3D LUT to adjust it when you by pass the OS and software. Plus the calibration would not be the most accurate match between the machine GPU and display. Furthermore, this would last until a driver update, which will break all of what you have done and you have to calibrate again. Plus the process for Calman is arduous, not well documented, take a long time, and price is the largest factor. I would say that if you don't have a very specific need or really high end job that really requirer this, then it is not worth it.

Wow! That's very complicated. 🔥🔥🔥🤯 It's like grandfather of PME.

[@ArtIsRight]

Yes, it is the mother of all PME. PME technically does the same thing with less control.

I'd love to see the same calibration but with ColourSpace from Light Illusion. I'm wondering if maybe their software is easier to use or if it's faster (or slower).

[@ArtIsRight]

That would be good. If they reached out to me, I would love to do a demo with their software.

I have the same plug usb type A to usb type B on my lg 27gl850 would i be able to use calman with xrite the same way here ?

[@ArtIsRight]

If your lg support such calibration then yes, you would have to check with LG.

Hi Art, Something I'm curious with about using CalMan for hardware calibration on the newer BenQ displays. With the older monitors (such as SW271 that I have) the PME software uses both hardware calibration as well as an ICC profile that gets loaded into your operating system. With these newer displays and using Calman, is it still using this type of "dual" calibration method? When using the monitor as a GUI, what ICC profile gets set by the operating system? My final question, would it be possible to use this monitor with a dedicated video output device like a Decklink thereby bypassing the OS color management and calibrate it via the hardware LUT calibration only? Thank you!

[@ArtIsRight]

Yes CalMan still uses ICM / ICC generated profile. With hardware calibration these icc profile does not contain color remapping information, mostly it is just gamut info. The icc used by the OS depends on the OS for Mac it will use the icc that you choose for Windows 10 all icc profile are generally ignored and only when color aware programs launch it will look to the OS for guidance as to which icc profile house. As far as calibrating with a device like Deck Link, I am have not test this so I am not certain if it is possible or not. If the card have an HDMI you can certainly turn and see if you can run Palette Master Element on that signal output with the SW271 it may work. If you have the card I would test it out, I don't have that hardware in my studio so I can't really test it.

Sir, What's the color space difference between Panel Native And Adobe RGB ?

[@ArtIsRight]

Panel Native is for BenQ SW similar to Adobe RGB but larger.

[@SachinBalan_PB]

@@ArtIsRight sir if i am using Colorchecker Passport for camera profile and edit photos in Photoshop and Lightroom. What working color space should be used ? Because camera profile is used for custom white balance and colour correction which exceeds AdobeRGB default. What to do in this situation when using SW2700PT and other SW monitor ?

[@ArtIsRight]

Panel Native, here's why kzbin.info/www/bejne/j6fYXqadmcmhl5I

[@ahmedeliwaph]

So is there is a real difference in result between calman and PME ?

[@ArtIsRight]

To be honest as far as my testing goes, the result is really close, I say that PME gets you 95% + of the way there. CalMan have some more specialize calibration mode but unless you need that and know for a fact that you need it, the cost for performance is null.

[@ahmedeliwaph]

@@ArtIsRight Thank you so much , other question please , i have calibarted my monitor as native and srgb and everything is great expect i feel the black and shadows in srgb mode darker than native panel mode ! is theres an explanation for that please ?

[@ArtIsRight]

What black point did you use for each of them? Did you use relative? If so it could be the limited sRGB gamut that is causing that issue. If both are not relative then I would recommend testing relative since the scaling is different.

[@ahmedeliwaph]

@@ArtIsRight Yes i use relative in both i watched all your videos and it really helps and i got the best results this is the only issue i don't understand blacks so dark even it can cover some shadows in my pictures i see it well while am editing in panel native but when i swap to srgb i can't see this shadows looks so so dark

[@ArtIsRight]

When you switch to sRGB, you are switching the calibration slot, are you also changing the profile in your OS? And did you quit and relaunch the program after? These process needs to be done for the program to take on the proper profile.

hello! Thank you for this great video!, I have some questions. I have the BenQsw2700PT, i am confused about the settings for the luminosity. here is what I am trying to do. I am creating two calibrations, one at D65 and one at D50 (I read that D50 is for editing for print? (lab print). I did the calibration for both however when I click the number one puck button it says RGB in lower corner of screen not calibration 1, i then click number 2 puck and it says sRGB instead of calibration 2.does this mean my calibration didn't save to the puck? I also seen in one of your videos you will use luminosity at 80 for editing? please advise me on the setting for print and for digital. i do allot of manipulation work as well as people. should i edit at 80 luminosity for both D65 and D50?

[@ArtIsRight]

Thank you. So a few things what you need is this video kzbin.info/www/bejne/ZpzZpqWlhMZ0iac you need to custom program this, otherwise it would be using the default from the factory. The calibration did save to the display. The video above will help. I would set the luminosity for both at 80. Have a look at this play list, these video talks about printing but it also talks about lighting to view your prints as well. kzbin.info/www/bejne/ZpzZpqWlhMZ0iac if you're starting out in color management I generally don't recommend anyone start with a dual calibration of D50 and the 65. The recommendation is it just stick with D65 and use a proper calibrate light 6500k bulb to view the prints. I have been color managing and printing for more than 20 years now and all the time I'm always calibrate my display to D65. I have a video that's coming out on this topic that I'm still working on. But these videos in the playlist I should share with you should get you started.
