Calibrating Benq SW27xx monitor in Linux

Hello,

I am from last week proud owner of Benq SW270C … This display has hardware calibration which means that the calibration probe communicates with Benq PMU/PME software (Palette Master Ultimate or Palette Master Element) running on Windows or Mac computer which communicates directly with connected display and saves the calibration inside the display as a selectable Color Mode (profile) into one of three slots `Calibration 1 … 3’ … This is for overview :slight_smile:

Now - even after reading this thread and other links I am more confused than anything other from calibration …

Q1 - DisplayCAL is useless to me to get the most of it, I just need Benq’s PMU/PME which runs only on Windows or Mac which saves the profile directly to display ?

Q2 - If so (Q1) can I use other computer (\w w$ or OSX that can run PMU/PME) to calibrate the display o.O ?? I’ve read elswhere people saying that calibration is per device (GPU) and OS and other people saying that’s not right … This is very confusing for me … I have my Linux computer that I use for all my artistic activities and which is just a primary and in fact only device that I want to use with display however I have other computers around (my wife’s Macs, my corporate work laptop with win, etc) that can run PMU/PME …

Q3 - :D, this will be hard :smiley: - which Color Mode (profile) on display should I use while working with that … It’s so confusing for me … Should I be switching back and forth the Color Modes (page 54 from User Manual) depending on what software I am working with in the moment ?? o.O Eg for example RT uses for RAW editing a RTv4_Large which is equivalent of ProPhoto and when I will send it to GIMP it will be suddenly RTv4_sRGB which is some `special’ sRGB (?sRGB on stereoids according RT manual) … As pointed out above, RT uses as a default profile ProPhoto (RTv4_Large) while DT uses liner Rec. 2020 RGB … should I be switching to Adobe RGB o.O since my display supports it or should I just don’t care and use sRGB color mode selected in display ??

thank you very much for helping me with answering questions above … everything related to this color science and technical stuff like these color profiles is quite a mystery to me …

cheers, ~dan

Hello, I can’t answer your question, but I’m looking forward to hearing from you. I’m currently working on a 16” laptop 100% SRGB compatible, but I’m also considering buying a larger screen and if possible 100% RGB or close, I think an EISO. EISO also has built-in calibration. I’m currently on Windows 11, and going back to Linux for my future PC seems difficult, precisely because of these things that concern hardware support and calibration.

Q1. Answered by Calibrating a Benq monitor with DisplayCal - #11 by gwgill

Q2 you can use displaycal as described above.

Q3 RT_v4Large et al are working profiles, those a re color spaces where your edit is made, not a color space where your edit is displayed. You want a large working gamut. This doesn’t really have an effect on your display profiles.

Q3+

so what would you recommend to set as a Color Mode on the display with OSD menu ?

Per the reply from Graeme:

The aim should (ideally) to run the display in its widest gamut/native mode. So you would normally select this mode as the one to use when calibrating/profiling and using the display. This could be something like a “user” setting mode.

I am using a DisplayCal on multiple computers to calibrate multiple screens running at the same time. I use three screens. I have kept my laptop screen set to the factory default presuming it may represent what the average online user might be seeing. I have my main editing monitor calibrated with DisplayCal software setting the profile and my third screen has a separate DisplayCal created profile.

I defer to more experienced users here, but for me DisplayCal is a better solution using multiple monitors than the software supplied with the screen or the calibration devices I own. It is reasonably straight forward to use. Goodluck resolving your issues.

my original question is still unanswered … is there any measurable difference if I will calibrate my display with other computer than with computer that I normally use with it ?

Oh yea, I have a very similar Benq screen.

You can do this:

  1. Hardware calibrate with the benq software, but don’t use the icc profile that’s created with it.

  2. Profile only with displaycal and use the profile that’s created with displaycal for your photo editing software.

Another possibility is to just use displaycal, use “calibration” with the help of the interactive tool of displaycal to set white point and brightness of the screen with the monitor buttons, then profile.
Currently I only use displaycal, but probably you will only be able the use screen’s native (biggest) color space if you use the benq hardware calibration tool.

No. You can use any computer for hardware calibrating anc profiling the screen.

None. Just Choose native rgb during hardware calibration, if you want the biggest color space.
The profile is then saved inside the screen and just activate in the osd the calibration that you created with pme/pmu.

Hi, I mean that I will just use other computer (my wife’s Mac or my work laptop with windows) for calibration with Benq’s PMU/PME software that saves the profile directly in display and then I will work with the display for photoediting with my computer where I have a Linux … Will this work ?

Ofc, to use a displaycal with my Linux is completely different story … It’s just something else …

Normally the workflow for Mac/Win users is that they will just use Benq’s PMU/PME software which employs so called `hardware calibration’ which is one of key marketing features of this display

Yes, but in addition to calibrating with the benq software, you must do a profiling with displaycal. The icc profiles that are created by palette master are not good.

Make yourself familiar with the difference between (hardware) calibration and profiling.

hmmm … I am missing something obviously … I’ve used my wifes’s mac and calibrated the display with PMU (Palette master ultimate) … Result ? Broken colors … Now the display has a green tint with profile created with probe + PMU … I had to go back to factory profiles and it’s OK … I am using built-in sRGB mode (page #54 here)

obviously it would be for me enough to just use a factory profiles (sRGB or some another one - please advise which if there’s some better than sRGB … mention, I use Linux and RT/DT/GIMP so I guess Adobe RGB is not for me for many reasons) and displayCal’s icc that I will use with particular application …

correct ?

Can you post some screenshots with the settings in palette master?
You know there is not much sense in using a wide gamut screen in srgb mode…

Hi, will do next time I will lend the calibration device …
