    This is what I was expecting from LG/Apple

    4K 27" HDR. Virtually no bezel. Decent design. This looks WAY better than the LG 4K, Dell has other "infinity edge" monitors I've seen, and they look as expected, not something out of 2008. Less vertical resolution than the LG which is a negative, and its bigger at 27" vs 24"

    No USB-C though which kind of sucks. It appears to have Mini DisplayPort. So will have to go USBC to Display Port, to Displayport to Mini DisplayPort. I don't see a USBC to Mini DisplayPort cable anywhere. Though I can find decent length USBC to Display Port cable, so won't have to use that goofy dongle Apple made.

    Like most other dell monitors (certainly the vaunted Ultrasharps) this offer several input methods, plenty of one cable solutions for USB-C to DP, mDP HDMI.

    1 x DP (ver. 1.2)
    1 x mDP (ver. 1.2)
    1 x HDMI (ver. 2.0)

    Hmm something does not seem right. The DP 1.4 spec has been reported all over the place, but somehow the Dell official website you link is listing it with DP 1.2?

    I have been researching on 4K monitors and this Dell UP2718Q was one of the options, but I had to dismiss it due to its DisplayPort needing version 1.4 for full 4k 60Hz HDR 10-bit. All Macs without TB3 can only do DP 1.2, where ones with TB3 like MBP 2016/17 and iMac 2017 can only do DP 1.3 via dongle.

    EDIT: okay I think I know the problem - there are 2 different models, U2718Q which is what OP linked, and another higher model with HDR 10-bit called UP2718Q.

    Yah Dell model names are confusing as heck.

    You are saying a 2016+ MacBook won't be able to run the linked 1.2 UP2718Q at 60 Hz ?

    I think you can, but not at the full 10-bit color depth, as that would require bandwidth only available in a DP 1.4 stream where no Macs currently are able to produce out of the box (with the exception of eGPU over TB3/2 but even that it sketchy on the OS side).

    In other words, the UP2718Q when used with a Mac, is not going to be taken full advantage on its 10 bit capability, which is a waste. The U2718Q you linked is a fitter choice, *but*, its color gamut is limited to DCi-P3 81% which is much less than the UP version which is at 97%.
