I have owned a Dell U2410 for a while, and I just bought a new Benq PD2700u and an iDisplayPro Plus (to replace my old Spyder). I calibrated both displays with DisplayCal and the iDPro, I used the same settings and targeted the same white point luminance for both. Except my U2410 has more contrast, saturation, and it’s brighter. It’s an obvious visible difference.
I did a simple 2.2 gamma D65 calibration with Single Curve + Matrix for both. The PD2700u returned 100% sRGB, and about 80% P3. The U2410 returned 100% sRGB and about 90% P3.
Why would the calibrations look so different? Why is the Dell so much brighter than the Benq when I measured them to have the same value with the iDPro? Is the Benq a bad monitor, I can still return it and get something different, maybe the new U2420q? Or is my Dell untrustworthy at this point, even after calibration? I’d love any enlightenment people can shed on the situation for me.
This is normally solved by using spectral corrections and color managed softwear. Because the U2410 is a famous model a high quality correction is included in the bundled list of corrections and normally auto-selected, so the results can be trusted. I don’t know but you can check if your Benq model is in the the user corrections database.
Since you are thinking about exchanging the Benq monitor and you want to use single curve+matrix profiles there’s definitely an advantage to something like a Eizo CS or CG series. Also you can expect better panel uniformity and interoperability with DisplayCAL is better.Thank you for the response, I forgot to mention, but I was able to find Spectral corrections for both the Benq and the Dell and applied them respectively.
I was able to get the brightness and contrast to match better by boosting the Benq to 200cdm for the calibration, while leaving the Dell at 150cdm. I work with a small amount of ambient light, so 80-120 is not enough for me. But with the 200 to 150 difference, they actually match much better, and the white level and contrast seem visually similar enough. Although, the Dell still has more saturation than the Benq has. Still not sure why or which monitor I should be trusting.
I used xyz + matrix for years, and colors looked fine in Resolve and Photoshop and other similar apps, but they always looked oversaturated on basic windows apps and Chrome (I set force color to sRGB). I recently tried using single curve + matrix based on advice I read on these forums in order to get more color consistency across the board, and planned to do a separate xyz + matrix profile that I would switch to when I use Photoshop and Lightroom, and use a Resolve 3D LUT with the single curve for Resolve. Let me know if that makes sense or if I should do something differently.
I appreciate the suggestion for the Eizo. I have been wanting one for a while, but it’s still out of my price range. Right now I’m in the $500-800 range, and this monitor will be my main monitor, daily driver, and future UI monitor, so 4k 27″ is important to me for the working resolution. But I’ll save up for a better reference display in the future. I had narrowed my search down to the Benq pd2700u and the Dell U2420q for this go around, and went with the Benq, but now I’m leaning towards the Dell. However, if you have any suggestions that might be a bit more in my price range, I’d be open to hearing them.
Appreciate the help.
Your approach makes sense to me. On my consumer class monitor single curve + introduces hue and tint shifts that doesn’t matter for casual browsing but obviously it’s bad for editing. That’s were Eizos have a reliability advantage cause you can use the same profile everywhere. There’s one Eizo CS 24″ that’s in your price range IIRC, worth every penny IMO. There’s no guarantee with a consumer class displays will be similarly well behaved though. I’m not saying they don’t exist but there’s a chance you will run into the same issue.
Although, the Dell still has more saturation than the Benq has. Still not sure why or which monitor I should be trusting.
That Dell is a widegamut, Benq is sRGB-like. Non color managed apps will send untranslated RGB values to display… and in a WG CFFL red 255 is far more saturated than in a white led SRGB display.
In a proper configured system with calibrated & profiled displays using color managed software like Photoshop and showing an image that fits inside both displays colorspaces there should be no saturatio issue. Outside that, if one of these condidions fall, they won’t render the same color.That’s really interesting and makes sense. I did open a few photos in both programs and it looks more similar, but still there seems to be a little bit more saturation on the Dell, but it’s closer. Also, the colors just looked more alive and better on the dell.
But it sounds like you’re saying that since the Dell is wide gamut, that the Benq is likely displaying more accurate colors in non color managed apps like Chrome, but they should be more similar in Photoshop and other apps like that?
