Hello everyone, I'm about the pull the trigger for a P2715Q, but I have some questions that need to be answered before I do so. Could you guys please help me on this one? For your information, I will be connecting this screen to my late 2013 15Rmbp with DGPU in clamshell mode.
1) Will my notebook support SST 60hz for this screen?
2) I have heard that there are no RGB controls? Can I use my i1display pro to calibrate it?
3) If I watch 1080p content or 4k content on youtube, will my fans start spinning all the time?
4) I intend to use the monitor in QHD resolution, I'm mainly interested in the retina feeling of the fonts, am I better off buying a U2515H?
5) Are the issues regarding the monitor not turning on resolved? I don't plan on unplugging it every time I want to use my computer.
Thank you very much for your help.
Yes, your rMBP will support SST 60Hz on that display. I have two connected to my rMBP, the same config as your but with a 1TB SSD.
Dell offers no OS support for this display (and most of their other displays). As shipped, our Macs see this and other Dell displays as a "television", as a composite device. There's a means to get around this, and I've done it - search this thread and the web for "Mac EDID" and you'll get more information; FWIW, Windows users have been doing this same workaround for years - it's like Dell saying "Thanks for the money, here's your display. Bye." My devices are now seen as RGB displays, and not as televisions - the workaround took maybe 15 minutes total. The displays have both RGB and composite settings and are fairly configurable. You'd also need to do this with the U2515H BTW...
The Dell comes calibrated, and with documentation for each display. I'm happy with mine, however, you may choose to refine your display's calibration.
I have checked out YouTube's 4k videos. They're spectacular. Yes, your rMBP will get hot - I keep a small fan aimed at my laptop and airflow in my home office is very good FWIW. I have a small stand under my rMBP as well, and will be mounting it on an arm soon. With the (fairly silent) fan trained on my rMBP, the fans in my laptop hardly ever turn on.
I can't answer your "4k or QHD display" question. I wanted a SST-capable 4k display (two, really) with specs like the P2715Q. The price was right at the time - they went on sale, and I bought from Dell directly as they're more responsive with direct purchases for warranty work IMHO. I also wanted some degree of futureproofing. I often use one display in portrait mode and one in landscape mode. I didn't even consider a QHD or other configuration.
Both of mine turn on maybe 39 out of 40 times. Both of mine are the first revision. I NEVER buy hardware until the initial builds are on other people's desks, but that's me - I read the complaints, and waited until the "Rev 0" builds were gone. I use a BT keyboard and sometimes the built-in keyboard, when I tap either of the "brightness" keys, the Mac and display(s) spring to life almost every time.
If you can wait a bit, there's a sweet display coming out soon, the BenQ BL2711U. We have the 32-inch version of this in my office and I've threatened to fire my employee so I can take his BenQ. Between the P2715Q and the BL2711U, if the smaller BenQ is like the larger sibling I'd buy the smaller BenQ and pay a bit more for it. My 2 cents...
