Will this monitor work with a 15" 2016 MBP?

    The monitor in question is the U2515H by dell. I know it doesn't have a USB-C port, but is there still a way to connect the two and get it at 60hz?

    If so how?

    Thanks!

    I have a similar monitor from Dell and it works fine via hdmi or DP. I have mine hooked up through a dock, but any hdmi or mDP adapter will work. The 60hz will work for sure at that resolution. The only issues with refresh are at 4k, where sometimes hdmi adapters don't work, but mDP should without issue. This is not a 4k monitor so it's irrelevant.

    Thanks for the reply, that makes perfect sense. Now I'm wondering if that monitor would give 60hz on a 2015 Macbook Pro with the integrated graphics card? I asked an apple rep and they said it wouldn't unless it has the Radeon graphics card in it but I've heard that the 2015 MBP without specifying if it has the extra graphics, can support a 4k monitor at 60hz with a DP to a mDP without issues. Is this correct? Maybe I should start a new thread for that one.

    I have a 13" with igpu only and I run the 34" dell at 60hz. These can all run 4k @ 60hz too. QHD is easy for these MBP's.

    As for a 2015, I will say probably given that the 13" 2016 only has igpu and does 60hz. I actually ran my monitor on a 2009 but only at 30hz. I am pretty certain the 2015's igpu's are closer to my 2016 than my 2009. But I'm sure someone here can verify with certainty.

    I have the lowest spec 2015 15" MBP and it runs a 27" Dell P2715Q 4k @ 60hz. The only hiccups I get are in Lightroom which has notoriously bad performance. Trying to edit photos at 5120 x 2880 has it understandably begging for mercy. A few of my friends run a 2015 15" MacBook pro with a large 4k monitor + a really ultra wide curved dell monitor at the same time and their machines are always breathing hard. Depending on the work you do I'd opt for a faster processor and gpu if you're really going to push it.

    Thanks for your reply. Yes I heard that it can support 4k just as you are using it, and that it can tax the laptop at times, that's why I opted for not 4k but a 1440p monitor instead, to give it some breathing room.

    A 4k monitor has 3840 pixels × 2160 lines so 8.3 Megapixels, a 1440p monitor has 3.7 Megapixels rounded up which less than half of a 4k monitor. I guess I'm answering my own question here but it sounds like it should work at 60hz it's just odd that the apple rep said it won't be able to run 60hz on a 1440p monitor. Does that make sense?

    By the way he looked it up and referred to this spec sheet for the answer

    It makes sense it can run multiples of that monitor the Apple rep is an idiot and can't extrapolate that if it can run 4 and 5 k monitors it can run anything else without breaking sweat. Basically don't take advice from people who can only look up something especially when they show no sign of understanding what they have read.

    Tap it into google there are videos of them running three monitors no worries.

    With at least the lower-end Dell tier of this monitor family, when used with this cable, it works well with the 2016. As the Dell display I use is 1080p, where as your tier is a 1440, I can't say for sure if you will get 60 Hz, but I don't see why you wouldn't.

    IIRC there are also some USB-C-->DisplayPort cables designed for 4k & 60.

    Yes it should work unless I'm missing something or not understanding some technical aspect but according to this article https://support.apple.com/en-ca/HT206587 the 2015 MBP can run a 4k monitor, so since a 1440p monitor is half the pixels it should work pretty well. That's my reasoning.

    UPDATE: I called them again and referenced this article and he concurred that it should work at 60hz with a DP to a mDP.
