Is there a DisplayPort version setting? If it's set to 1.4, try changing it to 1.2.
Afraid there is not. I read somewhere that all current Dell 4K displays need DP 1.4 whereas LG 4K displays also work with DP 1.2. Support for DP 1.4 was introduced with the 2018 Macbook Pro so all I can do is to get adapters and try out.

For the 15” and 16”.
The 13” didn’t support DisplayPort 1.4 until the 2020 “Ice Lake” generation.

Quick one, how low can the screen be pushed down on the 27inch and 32inch. Can anyone give me a dimension from the bottom of the bezels to the desk surface. My desk is quite high and I tend to push the monitor down low and what to check it goes down low enough or if I will need a monitor arm.

Thanks

Bought U3223QE from BLTSales. Ordered on 23 Feb arrived on 24 Feb (US) via free ground shipping option. $927 total. Manufactured Oct 21, A00 model. Connected to a 2020 i7 MacMini (Monterey 12.2.1) via the supplied USB-C to HDMI cable, scaling at 3008 x 1692 @60Hz. It's sitting on its stand now, may move it to an arm later. Haven't tried the KVM tools yet, may try it when I get some time.

I replaced an ultrawide that died and couldn't wait for the 'upcoming' Apple monitor. When I found this for <$1k I pulled the trigger. I use it for traditional productivity so no photo/video or gaming and it's just what I needed. It sits beside a LG5KUF @1440 retina and there is a difference but it's not noticeable enough for me to complain (too much).

Any questions?

Ok Debbie Downer! I was trying to explainM1 Mac mini only supports ONE external Display! [...]
There's no need to get personal. @dotck asked about connecting one monitor to a 2017 (Intel) MacBook Pro. They didn't mention two monitors or an M1 Mac mini.

@dotck: If these monitors really need two-lane DisplayPort 1.4 HBR3 for “4K” at 60 Hz, then I'd suggest trying a USB-C to HDMI 2.0 adapter and the monitor's HDMI input instead.

Doesn't work for me. Still get only 30 Hz.
I had similar issues w/ my U2720Q's (2 out of 3 of them) on my M1 Max MacBook Pro. No obvious reason, but I could only get YPpBr and occasionally they'd only give 30hz, despite having USB-C prioritization set to High Resolution.

You may also want to try turning off any HDR capabilities in the OSD menus. Ultimately for me, it was some combination of tinkering with HDR settings and/or unplugging/re-plugging my USB-C cable from the monitor and it now connects at 60hz w/ RGB.

He doesn't have an M1 Mac mini. He has a 2017 MacBook Pro. It should work as is.

I’m very tempted to order the 27” as it’s possibly the best alternative right now to replace my dinosaur of display. The issue I have is that my MBP is also very old, but still has maybe 1-2 years of life left in it.

So what would be the best way to connect a 2015 MBP 15” to the display with the goal of maximizing available resolution options and getting 60Hz? My MBP has 2x thunderbolt 2/mini-DP, and HDMI.
If the HDMI only gives out 30Hz then it only leaves Mini-DP as an option.


I’m eyeing this Lenovo Mini-DisplayPort-to-DisplayPort Cable as possible solution:



* The 20-pin Mini-DisplayPort is DisplayPort 1.2 compliant

* HDCP 1.3 and 21.6 Gbps of bandwidth

* The maximum resolution supported is 4096 x 2160 @ 60Hz


Though I’m not sure if the DP 1.2 would still curtail it to 30Hz on this particular Dell display.

These new Dell displays look like they require a two-lane DisplayPort 1.4 HBR3 connection for "4K" at 60 Hz; so, assuming they don't do "4K" at 60 Hz via four-lane DisplayPort 1.2 HBR2 (which is what your MBP has), then a possible solution - if your MBP has a discrete AMD GPU - is an active MiniDisplayPort 1.2 to HDMI 2.0 adapter and using a HDMI 2.0 cable to connect that to the display's HDMI 2.0 input.

Do not use the MBP's built-in HDMI 1.4 port; it won't give you "4K" at 60 Hz.

The reason your MBP needs the AMD GPU to pull this off is "4K" at 60 Hz via HDMI 2.0 requires a 594 MHz pixel clock which the AMD GPU should™ just be able to do; but if you have the Intel Iris Pro 5200 GPU, it's definitely limited to a 540 MHz pixel clock - just good enough for "4K" at 60 Hz via DisplayPort (because CVT-RB timings require a 533 MHz pixel clock), but not via HDMI.

Ordered the 27 inch version, bit of a wait for delivery. I can't make my mind up on this monitor for £685 or just get the LG 27UP850W for £400.

Thanks for the help!

My MBP is Intel Iris Pro 1536 MB (2,2 GHz Quad-Core Intel Core i7, with 16GB RAM) so I guess the HDMI option is out of question. But to be clear the display cable could work?

I’m not gaming or consuming 4K video content, mostly I’m planning to use the display for fairly light Illustrator and PS work (+procreate on ipad pro), so I’m hoping my MBP would be able to handle it without much lagging…

You mean the DisplayPort cable you linked to? That may well limit you to 30 Hz on these displays, because your MBP doesn't have DisplayPort 1.4.

The active MiniDisplayPort 1.2 to HDMI 2.0 adapter might still work... because even though the HDMI timings for "4K" at 60 Hz require too high a pixel clock for your MBP's GPU, it's possible that the display also accepts CVT-RB timings via HDMI which would allow you to get 60 Hz. You'd need to install SwitchResX and create a custom 3840×2160 60 Hz CVT-RB timing after connecting the display via the adapter to try that.

Or... just get another display known to do "4K" at 60 Hz via four-lane DisplayPort 1.2 (HBR2).

Thanks again for clarifying!

I'll look into the active adapter and SwitchResX.

The 27UP850 is definitely a nice monitor, but there is one major downside, it is heavily plagued by IPS glow. I had the 27UP600 which is based on exact the same BOE panel and could not get used to the extreme glow of it. See also this review where the following is said about it: ''On a black field, Glow manifests itself in all its glory, which is the norm for all IPS-type matrices without exception, but for the installed matrix from BOE it is really very strong.''

Any questions?
Update: Plugged in my 2021 M1 MBA using the LG5kUF via TB3 cable and the Dell through a CalDigit TB4 dock and StarTech USB32HD4k dongle w/DisplayLink so I could use both monitors. Still running the LG5KUF at 2560x1440 Retina, but the M1 MBA only allows native 3840x2160, 3008x1692, 2560x1440, 2040x1080 (and on down the line). 4k on a 32' is too small for me and the difference between it and 1440 is too jarring so it was time to scale. 3008x1692 was too blurry/fuzzy so I tried 2560x1440. It's noticeably blurry/fuzzy but minimally acceptable and the best balance for the dual monitor setup I'm using.

Options:
- Return the U3223QE it and look at ~40" 4k monitors to regain the sharpness and match UI size to 1440 Retina on a 27" monitor (Hassle and money)
- Just use the 2020 Intel MacMini (Bluetooth issues and fan noise)
- MacBook Pro w/M1 Max (Money)
- Keep waiting for that sweet sweet Apple Monitor or the new Air or Mini that might work better (promises promises)

Looks pretty nice. Being 4K, each having 400cd/m2 brightness, and being able to deliver 90W PD through USB-C with a decent hub on monitor means it can effectively act similar to the LG UltraFines w/ Thunderbolt 3 to be a 1-cable solution directly from MBP to monitor.
So is this monitor for $500 less:


Granted this Dell may have some better specs here and there (depending on your needs), but for $299 (has been as low as $239 at Samsung.com and $279 at Amazon for the speaker version), most of the features Dell is touting for $800 are in the $299 Samsung. The speaker is very good in this monitor. No speaker in the Dell. Again, all over 1 cable that also charges my MBP.

I have 2 of the Samsung monitors on my M1 Pro MacBooks and they're a gorgeous 1-cable solution.

Heck, for $800, Dell doesn't even include a proper USB-C cable to connect to your Mac:

Cables Included
1. Power cablei
2. DisplayPort 1.8 M cable (DisplayPort to DisplayPort)
3. USB-C Gen2 1.0 M cable (A to C)

Got one now and very happy with it. Haven't checked for backlight bleeding or anything like that - no reason since is will always be used in a light environment. Those looking for a monitor for productivity/office work will probably be happy with this monitor. Only thing I've noticed is that the screen on my Macbook is way more white, where the white areas on the Dell are kinda yellow. But only noticeable if the two screens are viewed side by side. Had not noticed until the Macbook was lined up next to the monitor.

Probably the color temperature of your MacBook is too high, which means that white has actually a blueish tint, but to the human eye it looks more white. The Dell monitor has the correct color temperature, sitting near the 6500K.

Try changing the Dell preset color to the “Movie” setting. I noticed it makes the screen less warm looking to me.

That is indeed an option. You could also set the color temperature in the Color settings to 7500K or higher if you prefer.

I don't see the option of changing Color settings in the 'joy stick' menu? Can only select preset modes or brightness/contrast. Couldn't find it in the manual either...

Edit: Found it! Thanks for pointing this option out. :)

Edit 2: True Tone was enabled on the Macbook that was connected to the Dell monitor. Disabling this fixed it.
