I've been reading online about how the P2415Q (and possibly Dell monitors in general) has issues with waking from sleep when used with Macs (and sometimes PCs too). Some people say "Hey I got Revision A03, the issue is gone!" and some have said "I have Revision A03 but sometimes it stays stuck in sleep mode". Most of this feedback is from Amazon, where some people are talking about their "5K displays" in the reviews for this 4K 24" monitor, so I'm hoping I can get feedback from Macrumors regarding the exact situation with the P2415Q. Does anyone know the differences between revisions? I know Dell doesn't like to disclose that info, but maybe someone has figured something out... Does any Revision in particular fix the sleep issue? Or do none of them? All I know is that there exists A00, A01, A02 and A03, and some have reported having A03 as early as March 2015, while a supposed Dell employee in one Dell thread stated the A03 didn't start shipping until August 2015. Nevertheless, many report that third-party sellers on Amazon are still shipping out A01 and A02 models, in which case I'm not expecting to get A03. Finally, I hear that you can ship off your brand new monitor to Dell so they can replace it with an A03 refurb with quite possibly dead pixels/other issues/the same sleep issues- has anyone gone through this process? I added a poll to hopefully make things a little easier for those who just want to report their situation and move on. Thank you!
