It's not a threat. I got an email like this about 6 months ago from Amazon. I then had a monitor replaced due to a defect about a month later and bam, they permanently closed my Amazon account. I returned for replacement or refund about 10 monitors and TV's total over a 10 year period and even though I spent over 100k with Amazon during that time. So fair warning to others out there, Amazon will not hesitate to close your account for too many refunds or replacements even though the items were all defective. I tried to reach them and it was almost impossible. Customer Service refused to discuss it and that "Account Specialist" department doesn't have a phone number to reach them. Once they close your account, you're done. So be careful, use your returns/replacements wisely with Amazon.

Wow, sorry to hear that... and thank you for sharing with us. That for sure ends my lottery pursuits, at least with Amazon. So once this happens, you are pretty much screwed right? I mean you could set up another account with another email address, but I would imagine they would catch on once you add your credit card.

If after calibrating again, you end up with something that's still too warm for your liking, you could always change the settings in DisplayCal to calibrate to something slightly cooler like 7500K. The nice thing is you can use that interactive calibration at the beginning to adjust your RGB levels to whatever whitepoint you specified.

After doing a little reading, I'm not sure a colorimeter is able to give a 100% correct whitepoint reading, but it should be in the ballpark. It should be accurate for the gamma though, which you mentioned was your main annoyance to begin with. Unless you are doing color critical work, the whitepoint is really just a matter of preference anyway.

Edit: FYI those choices you have in DisplayCal for the correction, I think they're all based on the backlight... for example, there's W-LED (the most common now), RGB-LED (pro displays), OLED, Plasma, CRT, etc. It's useful to know if you want to calibrate another monitor or TV.

Not sure how it works then..... I sent back around the same amount, and I received an email from them as well asking about the returns. So I am done with the lottery with Amazon.

The imported correction for i1 display pro is "Spectral: LCD White LED IPS (WLED AC LG Samsung)". Not sure if it's same on colormunki, but that's what I would look for. I think any with WLED is probably going to be close. Also, Under tools at top there's "report on calibrated device report" that will show some good information and there's also a good HTML report you can generate with verification tab.

Here's what my after cal report looked like (brightness a little low. I keep room dim):

Anyone know why this monitor is out of stock everywhere in the UK and has been for a long time? Is it just because people are buying and returning so many looking for the perfect one? I ordered one a few weeks ago but the unit I received had clearly already been used and the backlight bleed was horrible. I finally found another in stock this weekend that said it would be delivered by 3rd Feb but changed to 16th March after I placed the order.

I placed an order with Amazon.it and it says it'll be available in 2-4 weeks. I wouldn't mind waiting that long but I know Amazon can change that ETA whenever they want. There's also a very good chance that even if I ever get it from them I will have to return it due to defects.

Anyone in the UK having better luck?

Thanks. I've attached a screenshot of the report HTML file. I think it looks better than my prior trials. I'd like better contrast and black level, but that may have to do with me setting the monitor as close to 120 cd/m2 prior to running the calibration, not sure.

The email isn't a threat to close your account. I got also its just asking how they can better serve you. If anyone is worried just call and explain the situation they are well aware of the problems with these monitors.

After playing quite some time with ColorMunki's software I must say that it has a few advantages over DisplayCAL (it changed name in the last version wink.gif):

1) Speed - it's very fast to get a basic, good looking profile in ColorMunki

2) ADC (automatic OSD settings adjustment) is great for getting the initial monitor settings right. It doesn't work everywhere and in some cases (like on Dell S2716DG) it will cause the monitor to soft-brick on sleep/poweroff, this requires a full power cycle and resets every setting in the OSD so I had to read the raw values with softMCCS to get back what ColorMunki actually set. This is the monitor's fault since it also reacts like that on brightness changes in softMCCS and I had it on 2 different ones.

3) Profiles that require heavy gamma corrections look subjectively better - even when the results are measured with DisplayCAL the gamma response seems better with ColorMunki's profile:



DisplayCAL on the left, ColorMunki on the right. While ΔE seems higher in ColorMunki's case look at how the measured gamma (V) actually behaves - it's closer to 2.2 in the darker shades, and as I said it just looks better subjectively wink.gif

DisplayCAL has killer features though: ReShade 3D LUT generation, great diagnostics and reporting, a profile enforcer (new in the newest version). I couldn't have used my Dell without it smile.gif

I'd advise trying out different options in both software suites and generally playing with them - I've learned a lot doing that.
