    Hello, Macforum

    I currently own an IPS display with 27" and resolution of 1080p (LG IPS277L). Recently I've been thinking about upgrading to a monitor with a higher resolution since the PPI of my current monitor is pretty low. I've browsed through lots of stores and realised that prices of 4k monitors aren't much higher than prices of monitors equipped with lower resolution (1440p, 1600p etc.). I use my monitor mainly for work on my MacBook but also for games on my gaming desktop PC (with Windows installed) and occasionaly for gaming on Xbox One.
    So far Dell P2715Q is the monitor I think would be the best for me. For about $550 you get a 27" IPS display with 4k resolution and 3 video inputs (HDMI, mDP and DP).
    I heard that you will only be able to get about 52Hz at 4k resolution with rMBP 13''. I thought about maybe lowering the resolution a little bit so I could reach 60Hz. Do you think it would be possible? And what resolution would you recommend me?
    And how about the other two devices? Which input port should I use for which device? I thought about using the HDMI for the Xbox, DP for the desktop PC and plugging the rMBP via mDP. Would it be possible or would there be some quality loss? What do you think apout the delay and input lag with the monitor I mentioned above. Will it be critical for gaming (I play lots of different kinds of games from sport and racing games to FPS)?

    Thank you for your answers.

    If you have to reduce resolution to run at 60 Hz, that kind of defeats the purpose of a 4K display, doesn't it?

    The new 13" rMBPs with Iris 6100 can natively drive 4K @ 60 Hz though.

    That said, you'll be better off with a smaller monitor but with 2560x1440 resolution, if you can find one.

    Thank you for your reply.

    As I said. The prices of 4k monitors seem to be only slightly higher than prices of 1440p monitors (at least where I live). Plus it will be better in the future when I will have a better PC that will actually be able to run 4k resolution at 60Hz. I am not planning on buying a newer MB anytime soon though.

    The cheaper 4K are a bit meh

    As with anything you get what you pay for, the cheaper 4K screens tend to be not so good on colour, general quality, refresh rate etc etc.

    Whereas the 1440 and 1600 screens available have been the high definition ones for professional users for years and are usually much better quality well calibrated and show good colour gamut, definition and refresh rate.

    I'm annoyingly running into an issue where it won't output a signal when I'm trying to run anything at over 30hz 1080p. I've got pretty much everything set up as you do. Any tips?
    I'm using all the right cables and such.
