In the meantime, I will skip over this problem, pretending it doesn’t exist. What? I don’t have windows! Can’t run Palette Master? What does it even mean “use hardware calibration”? Can’t I calibrate my Benq SW2700 with Displa圜AL? You need to use hardware calibration with the BenQ calibration (Palette Master Element) tool and a colorimeter with this screen. Another discussion about internal monitor calibration didnt make things any clearer. Then, I have understood that maybe this monitor has a “hardware calibration” which makes things even more complicated than they are I have read this discussion here on the forum, featuring an old friend of us dealing with a similar monitor and could not come up with a final solution. The only thing here is to choose a colorimeter correction for my colormunki, I have found this old thread on the Displa圜AL forum where attached a “correction file” to be used for this Benq SW2700, so I use this. All of this on Linux (Ubuntu 21.04), using r-darktable / dt 4.0. I decided this time to describe what I do and perhaps someone in this community will tell me on what is right or wrong.ĭetails first: I’m calibrating a Benq SW2700P monitor with the Displa圜al-p圓 fork by and an XRite Colormunki Display (bought in 2013, no longer produced). I’m trying to keep it simple (so things like gamma 2.2, 6500K, 120 cd/m2 etc, for those who already know these details) I perform the calibration in the evening, with the usual light that I have, no other variables. Ok I know this sounds little strange for an electronic gizmo, but I've had for 10 years, the same color calibrator.Each time I decide to be brave and calibrate my screens I always end up with more doubts than before (not to mention the feeling of being immensely stupid). There are newer ones out there, but for a device that I literally use once a year, it seems sad to have to buy a new one. This is the Spyder3 and about three years ago, DataColor discontinued support for it. So my monitors have not been calibrated for a long time. There is an open source project called Displa圜al which dispenses with the proprietary software, but for the last year, every time I've tried to use it with the Spyder3, it has crashed. So here are notes on how to make an old Spyder3 work with Displa圜al: Well, with all this pandemic isolation time on me, I've been fixing the house and thought I'd give it one last try before trashing the Spyder3 and getting a new calibrator (more on that below). Installation is easy with brew install displaycal which is great!. First of all, there are no real instructions for this as it's a pro tool.So when you get the first screen, it will ask you about downloading. So first plug in the Spyder3 to your Mac and it should detect it and download some software.Now it asks whether you want a black background.Make sure to select no, otherwise you can't see the calibration menus. I really got stuck on this as the window is behind the black background. If you have multiple monitors, then make sure to move that window away before starting.The startup time is long like a minute, so be patient, but eventually, it should have a dialog with a button that says Start Measurement the point here is to get your monitor roughly right.It then will show a grey color swatch and you click. The most important thing is actually at the bottom which is the light output.The thing is constantly taking measurements and emits a click sound. You need to set the brightness of your monitor to the right level. It is confusing because the top part which about targets and you want to get Red, Green and Blue in the center. The arrow is just what you had it first set at and gives you the brightness measured in Cd/m^2 (don't ask, but this is candlepower per square meter).Here you have to manually figure out how bright you want things.If you are doing prepress, then you want it at 80-120 and the room should be dark.
