    Hi,

    Unfortunately, I'm not able to get my new Philips 499P display working with native 5120x1440 resolution on my late 2014 iMac 5K. I'm seriously considering buying maxed out 2018 mac mini, as my new workstation. Does anyone successfully connected 5120x1440 display to 2018 mac mini? I don't really want to go through the whole return process if it won't work.

    Thanks!

    It'll work, as the specs say so:

    • Up to two displays:
    • One display with 5120-by-2880 resolution at 60Hz connected via Thunderbolt 3 plus one display with 4096-by-2160 resolution at 60Hz connected via HDMI 2.0

    Your Imac can't do it: https://support.apple.com/kb/SP707?locale=en_US

    • Simultaneously supports full native resolution on the built-in display and up to 3840 by 2160 pixels on an external display

    The 2014 iMac limits output to 3840x2160 pixels so the raw pixels should support 5120x1440 with room to spare. In Bootcamp almost all devices that can output 4K can output 5120x1440 so this is likely a software issue. Apparently only the LG 5K displays they sold in store are supported under Mac.

    In this post (https://discussions.apple.com/thread/8641919?answerId=250851537022#250851537022) the Mac Mini doesn't support it but some have had success with a USB-C to DisplayPort cable.

    In this post (https://discussions.apple.com/thread/8641919?answerId=250482121022#250482121022) someone managed 5120x1140 70Hz with SwitchResX on a 499P9 and a MacBook Pro.

    It looks like you need discrete graphics for this so your existing iMac has a better chance than the new Mac Mini that only has integrated graphics. Some people have also managed picture-by-picture with two cables, so you can also try that.

    You can try Retina Display Menu: https://github.com/avibrazil/RDM or SwitchResX: https://www.madrau.com to see if you can get it to use a custom resolution.

    I have a 2018 mac mini with a 499P and it doesn't support 5120x1440 resolution. Also tried SwitchResX to no avail.
    It's not the hardware, because when I boot it up with windows it does run at that res.

    I use a 2018 Mac Mini with the Dell U4919DW. I cannot speak to the native 5120x1440 via Thunderbolt (can test later this evening). Instead, I actually prefer the method of connecting two separate HDMI and/or DisplayPort inputs and using the monitor ODS to "trick" the Mac into treating the single display as two displays side-by-side. Works seamlessly and is much better for window management, IMO.

    Small image attached (sorry for the small pic - there is mildly sensitive data on the screen and I'm not at my home office to take a new one).

    Yes, that is a solution, but I like my desk full of displays, so using all outputs to drive one display is not really for me.

    This may actually drive me to switch back to windows after 5 years with macs.

    Thanks!

    Ah, gotcha. I never did test the USB-C cable, but now that I know this thread is still alive I'll try to get you an actual answer this weekend.

    I just purchased the refreshed LG 5K display to be directly connected to my 2018 Mac Mini (i7 w/ 64GB RAM) with the included Thunderbolt cable. Running at the Retina 2560x1440 equivalent resolution. No issues whatsoever, even at boot. Lag is no worse than with my previous 3440x1440 Dell widescreen QHD display.

    Seems that even tho it can run 5K display it fails (all macs) to output half 5K resolution. Best guess right now is that is a software issue because the same hardware can output such resolution under boot camp.

    Anyway, thanks for your input!

    Can confirm even over USB-C the resolution maxes out at something like 3440x1080, not 5120x1440 on the 2018 Mac Mini with a Dell U4919DW. Sorry, man.
