Ah yes, the wonderful "Asus RMA" is something I do not wan to experience and yes the PA329Q is older. This and I guess I will get a news Batch from BenQ since Amazon.de is expecting new stock on the 12th of December..old stock is gone.
Anyway, I have been digging around the net for info on a replacement model for the SW320 and can't find anything.
TFT Central has an article about Upcoming High Refresh Rate Panels and Displays
I can't see something with AdobeRGB coming anytime soon to make me skip the SW320. Yet, I plan on getting a second display in the future so if I have my color proofing workflow covered I can then focus on other aspects such as Refresh Rate, Contrast/HDR. The SW320 will also be written as a company expense so at the end of the day I am saving me some tax through it.
