Hey guys.
So i am very very new to the world of color grading for video. I already got a blackmagic intensity shuttle to get a clean video feed, and a i1display pro to do calibration, now just need to get a monitor.
I’ve decided to get a Benq SW270c because the cheapest Eizo i can get is triple the price of that and is like 2 months salary if i didn’t have any commitments at all.
Now, the store I’m purchasing from has guaranteed a 7 day return if there are any issues at all with the monitor.
So please walk me through what kind of test i should run on displaycal on my monitor to make sure it’s uniform and colour accurate as can be.
Planning to work mostly in Rec709 (but the option to do DCI-P3 sort of is nice)
Calibrite Display Pro HL on Amazon
Disclosure: As an Amazon Associate I earn from qualifying purchases.IDNK where do you live but typical SW270C and its associated poor QC and color uniformity issues is about 700euro (actually almost 800euro) and Eizo equivalent is CS2731 and cost 1000euro. Aproximate prices in EU. This is not 3x price.
Basic test with this kind of extremely poor QC monitors is DisplayCAL uniformity report @D65 white point. Also contrast test at the same white point.
It is expected to fail 1st (ISO conditions) but if you are lucky (actually EXTREMELY lucky) in amore relaxed verification params (change combo to deltaC in report) you may get less than 3dC in corners and less than 2dC surrounding center and up to -15% brightness drop on corners. That is not good, but reasonable.
It may pass ISO test but them (prad.de among others) contrast is likely to be destroyed by some factory uniformity compensation that cannot be switched off. If you want a monitor for video… 900:1 seems a reasonable (&low) bar for a common IPS-AHVA panel @D65.
Since CS2731 would pass dC<2 in all screen just for 300euro more with uniformity compensation off (900-1000:1)… I don’t think that your choice of a Benq SW is good.If uniformity is OK all white or grey calibration issues can be solved in GPU calibrating with DIsplayCAL (as long as your GPU casues no banding when loading calibrations) or trying its (defective) HW calibration (because of the too many faults Palette Master Elements, “PME”).. our you may even load a LUT3D for Davinci Resolve if you do video.
I mean uniformity is a mandatory requirement because you cannot solve it, faulty HW calibration can be solved with GPU grey calibration of software LUT3D. It’s… an extra (a very interesting one).IDNK which backlight is used in this SW270C, maybe AdobeRGB+P3 QLED from other cheap AHVA panels from AUO like other benqs (SW2700PT), or GB-LED or WLED PFS (AdobeRGB+P3 flavor). Check community database, look for spectral corrections “CCSS”, 3nm.
An i1d3 colorimeter (i1displaypro family) is recommended for these tests, same for Eizo CS2731. If that monitor has some WLED PFS backlight an Xrite spectrophotometer will have difficulties measuring actual spectral power distribution, an i1d3 is recommended. If you wish to use HW calibration features it needs to be i1displaypro, not cheaper i1d3 models and that applies to both monitors.
Thanks for the breakdown.
I’m from Malaysia, and it’s easier to buy drugs than to buy an Eizo monitor here.
There is one local distributor, but last i checked the “cheapest” model they could offer me was a 247x display model which was going for about the equivalent of 1970 euros.
I could ship a 2731 from Amazon Japan, but I’m not confident about having shipping something that big and fragile.
But will check with the local distro again if they have a 2731.
CS2740 is an UHD model, equivalent in specs to Benq model SW271 (bad quality, up to 4dC uniformity issues near the center!). CS2740 which is about 500euro more expensive than CS2731, about 1500-1600 euros in EU.
CS2731 is an QHD model and replaces CS2370, maybe this old model (end of life ) can be bouh in Malaysia.But maybe you said CG247x, it’s 24″ 1920×1200 and it’s about 1400 euros. It’s more expensive because 1500:1 panel and LUT3D.
Actual equivalent to that SW270C is Eizo CS series, 27″ QHD. You need to look for that, not to other more expensive models, otherwise you’ll compare apples & oranges.
