I found a site (!) with a good review of a 4K 31" monitor, which included the result of a full uniformity analysis, for those who are interested: https://photographylife.com/reviews/benq-sw320 Scroll towards the bottom of the page to find the (DispCal) uniformity report. It's a lot of numbers but the information is *invaluable*, IMO: https://1drv.ms/b/s!AkD78CVR1NBqkt8GT4_TY9ifwXDwUA?e=K1DScO I'm not trying to bash anyone but If every 31" monitor of this make, coming out of the assembly line have a similar "Uniformity profile", ranging from 98 (-18%) to 121 Cd/m2, using the accepted 10% tolerance criteria then... well, you can draw your own conclusions. / Roger
