I remember. I'm on Q3279VWFD8 31.5" IPS right now 75cm away and to get it there I had to push it as far back as I can at the moment. Even IPS at this distance and size is not really for graphics editing not on PRO level, for home, sure but not pro and I doubt the 1000+ EUR IPS are much better with viewing angles.
The PD3220U is new and has 95% DCI-P3 advertised, no calibration in hardware, other PD don't have wide gamut. So you should be able to use AdobeRGB with it, only software calibration though. PD is more of a middle ground for home use I think.
They all often use the same panels what differs is their electronics (OSD, firmware, options, factory calibration quality). The EIZO, NEC and same/similar specs monitor from other brands is likely the same panel.
If it's true 10bit that's nice but one needs Quadro/Fire card to get the drivers that support 10bit
They kind of lock it out of consumer cards (GeForce, Polaris/VEGA), Nvidia does for sure, AMD usually people have a bit better luck getting it to work more with 10bit. Probably know more than me here. Something about Photoshop needing OpenGL 10bit support which is missing on GeForce drivers.
1D LUT seems outdated to me. BenQ may not be as old staple in professional oriented monitors but they do try to enter pro and office markets with nice products in the last decade.
If it was me I would try SW271
for pro use if you are sure you can't be without hardware calibration and need the "best". For sRGB the PD2700U is a good choice at least for home use but not for you. I like EIZO and NEC but they don't really seem to compete and care anymore (about regular people, all business business customers) so I think there is space for BenQ and other to offer same/similar at better value. EIZO CG is nice, CS seems dead. PA272W is dead
, can you even buy it? I don't see anyone selling it, no stock anywhere. PA271Q
-BK-SV replaces it and both seems to advertise 3D LUT, it is available and cost is similar.
Well Amazon.de is fine with returns, I would suggest asking first to be sure and include your country, with mine it's fine and I think it should be fine to all EU. Speaking English to them is OK as long as you write during day hours otherwise my luck with their customer service is lower (they also have people with local language of countries they ship to, they replied to me once in local but I don't write to them in local). As far as refunding return shipping goes they refund 8.40 EUR which is low for shipping a monitor (often 2-3x of that using cheapest available shipping, insured) so what you do is send them copy of invoice you paid for the return shipping and they will refund you that. Which means you could get the monitor try it for 2 weeks, though maybe Amazon allows 4 weeks but I always tell them within 2 weeks (often same or next day of receiving when it's defective) and then it will show you until when you have to send it back (often 1 month), officially the free return shipping (refund of it) is only probably covered when you decide within 2 weeks of delivery.
They do get eventually suspicious if you roll a few monitors consecutively, as in trying to get a defect free high refresh monitor when they have terrible lottery, but so far it was OK to write them back and explain that monitors were defective and were indeed returned as such with descriptions of defects or other unacceptable quality issues.
Also have to remember that buying on Amazon.de does not always mean buying from Amazon.de, there are many sellers on there so you have to check details and select the seller you want, if you want to deal with Amazon.de and be covered by their policies and so on it has to be sold by Amazon.de, the policies for 3rd party sellers are not bad but you will have to deal with the 3rd party seller to resolve returns, refunds, exchanges, some are also sold as "fullfilled by Amazon" then those should be handled by Amazon.de as if it was sold by Amazon.de (it probably ships from their warehouses too and they simply handle those items for 3rd party sellers).
Other German etailers also offer free return shipping but you have to ask to be sure. computeruniverse.de (at least to my country), caseking.de?
Starting return with Amazon is simple since it's all automated on their web, only to get full refund of shipping you need to write them. Or if you return multiple monitors and deal with replacements instead of refunds then sure it is a bit of emailing to get replacements as they are not always offered via the web interface when doing a return. Or they get things messed up when you return 3+ monitors including all replacements and it may take them long time to refund you so write them and they will sort it out, ask you for a statement that you have indeed returned it all.
Christmas will be busy for Amazon to process returns especially after
holidays, people return unwanted gifts. Expect delays, plus return shipping costs go up with couriers in December as they get slammed with shipping christmas gifts and overall it's a selling season = tons of shipping from shops, between companies, from people, ...
Try SW271, if you don't like it, return it, maybe you will want the bigger variant or go with 1440p only (doubtful, no one likes to go down in resolution) or EIZO/NEC if the panel used in BenQ seems not as good as hoped.
