dell released their newest ultrasharp model ,U2723QE, U3223QE ultrasharp monitor

[RabidMacFan]

How is the hub on this? Any problems?

When connecting with only one USB-C cable, the bandwidth will be significantly constrained.

Upstream:
1 USB-C Display Port HBR3 over USB-C Upstream (8.1 Gbps per lane, up to four lanes)
1 USB-C Secondary port (10Gbps)

Downstream:
5 USB A Downstream Ports (10 Gbps EACH)
1 USB-C downstream Port (10 Gbps)
1 Ethernet Port (1 Gbps)

That would be 61 Gbps downstream if maxed out, way above USB-C specs even if you connected two USB-C cables from the monitor to your computer. How does the monitor handle this? Does it simply advertise Superspeed compatibility with devices, but provide a slower speed for all I/O? How much can you actually get with 1 USB-C cable connected, versus two?

Got the U2723QE replacement unit today. This time they sent me a new unit with original seal and all accessories. Still REV A00 manufactured in Nov 2021.

However I'm very disappointed in this particular panel. It's unbelievably yellow, compared to S2722QC and MacBook Pro 15". It's even a lot more yellow than the original unit. As a reference, the first unit has the same color temperature as S2722QC RGB setting 97% red + 100% green + 97% blue. This one has the same color temperature as S2722QC RGB setting = 97% red + 100% green + 93% blue. Can't believe quality can vary this much.

This one is unfortunately going back again and I'll look elsewhere.

Wait... you are disappointed because your screen looks yellow:

- compared to your Macbook
- uncalibrated

Every panel will look different with the same settings, that's why it's necessary to calibrate.

I thought U series panels are factory calibrated, no?

 

[grator]

I guess they are only in sRGB, Rec709 and P3 modes.

 

[RabidMacFan]

I guess they are only in sRGB, Rec709 and P3 modes.

Regarding the modes that you configure from the On-Screen Display - when you do this, do you leave the default color profile selected in System Preferences > Displays? Is that the way to get the most accurate P3 mode?

If you want to change the Color Profile in System Preferences, what should the settings on the display be set to, custom?

 

[Jeo_cz]

I thought U series panels are factory calibrated, no?

They are. But it means nothing. Colors depend on the signal from your GPU. And because each hardware sends different values, it's impossible to precalibrate displays to all of them. So go to the menu and change the color settings. Or even better, use the HW calibrator (eg. i1 Display Profiler) and calibrate both your displays (MacBook and Dell).

What grator is saying is correct. The U2723QE is only factory calibrated for the sRGB, Rec709 and DCI-P3 modes. Not for the Standard mode. However, as I've tested and measured four samples, the Standard mode is still very accurate, but I saw too differences in color temperature in the Standard mode between the different samples. One being more yellowish than the other. My experience with Dell monitors is that there's always a small but noticable difference, I saw this also with the U2720Q.

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.

Do you know whether there is an overview of Macs supporting DisplayPort 1.4 HBR3 and hence are fully compatible with these displays?

TechRadar is a little disappointed about the (perceived) contrast of the U3223QE.

 

[Clonetrooper]

Got mine today, the 27 inch model. Really impressed with the picture quality and sharpness using my M1 mini. Backlight bleed is pretty bad but tbh it was on my older monitors and it's never bothered me for what I do.

So I have a Spyder calibrator. If I do that do I then select the custom profile on the preset modes or leave it at standard and the colour profile is added via software? So if I'm reading the above correctly, preset mode 'colour space' is the mode to use for SRGB factory calibrated?

If you want to use one of the factory calibrated modes, you have to use either sRGB, Rec709 or DCI-P3, that's indeed the Color Space mode. So if you want to use the sRGB color space, you need to select sRGB.

TechRadar is a little disappointed about the (perceived) contrast of the U3223QE.

Indeed. The thing is, even if the contrast is twice what we usually see with IPS panels, it's still only 2000:1 with a black level between 0.06 and 0.07, when a entree level VA panel has a 0.03 value with the same lum and without local dimming.
So on the paper it's really better, but in real life, it's just better (imo).

Apparently my MacBook Pro ("MacBook Pro (16-inch, 2019)") is supported but Dell's U3223QE does only offer USB 2.0 if 4K and 60Hz are in use. Making use if Apple's Thunderbolt 3 (USB-C) cable didn't change the situation.

From Apple's USB-C adapter page:

3840x2160 at 60Hz on: [DisplayPort 1.4/HBR3 compatible]
iPad Pro 11-inch, iPad Pro 12.9-inch (3rd generation and later), MacBook Pro (16-inch, 2019), MacBook Pro (15-inch, 2017 and later), MacBook Pro (13-inch, four Thunderbolt 3 ports, 2020), MacBook Air (2020), iMac (Retina 5K, 27-inch, 2017 and later), iMac (Retina 4K, 21.5-inch, 2017 and later), and iMac Pro (2017 and later)

1080p at 60Hz or UHD (3840 by 2160) at 30Hz on: [DisplayPort 1.2/HBR2 compatible]
iPad Air (4th generation), MacBook Air (2018 and later), MacBook Pro (13-inch, 2016 and later), MacBook Pro (15-inch, 2016), iMac (non-Retina, 21.5‑inch, 2017), and Mac mini (2018)

Since those specific specs are not mentioned in the technical specs for each model, that's a clever way to answer the question. Another way to know is that anything with Thunderbolt 3 (or USB4, or Thunderbolt 4) will support DisplayPort 1.4/HBR3.

Another thing to keep in mind is that even if your computer is DP1.4, many Docking stations and hubs are only DP1.2. The popular CalDigit TS3+ for example. You'll need the new TS4 to get DP1.4.

I had a Dell U2720Q for a while and it was able to support 4K 60Hz with Prioritize Resolution enabled on the same machine, no problem.

Changing to Prioritize Bandwidth DID speed up the ports, but only at 30Hz and when not connected with a dock. However, after a reboot of the computer and the monitor, and connecting directly to it, I could get 60Hz as well.

Not quite. For example, 2016 MacBook pro 15 and Macbook pro 13 before 2020 have Thounderbolt 3 but don't seem to support DisplayPort 1.4/HBR3.

Have you tried changing USB-C Prioritization to High Data Speed?

 

[justsomerandomaccount]

Have you tried changing USB-C Prioritization to High Data Speed?

Yes. "High Data Speed" is resulting in USB 3.1 etc. for data transfers but does only support 4k 30Hz. I don't quite understand whether that's a software problem or a hardware driven limitation.

 

[Clonetrooper]

So how do I connect a Mac mini and my Mrs Windows Laptop at the same time and use the Hub options on both, is this possible?

Currently I have the Mac mini connected with the supplied USB C cable, So I can use all the hub connections.
My Wife's Laptop is connected via display port and she is charging it via one of those Thinkpad devices. Is there a way to get rid of that and use both devices?

I think you are talking about the KVM feature. You can connect your Mac with one of the Display ports and USB-C Upstream, and the windows laptop with USB-C. WIth a few clicks in the menu you can swap which device the USB downstream ports get assigned to. You probably only want to use that for Keyboards and mice though, because if you do a swap with an active USB storage device, you could lose data.

From the on-screen display, go to the USB controls.

 

[81Tiger04]

Just an FYI ... Both monitors are on sale. The U3223QE is down from $1,149 to $919 and the U2723QE is down from $779 to $624.

So if I'm reading this correctly I connect there Mac mini with HDMI and USB A to the other USB C port? Does all the hub functions still work?

1 day before I got mine. **** Ah no just checked and it's still 640 in the uk.

Call back in for a Price Match. It took about 10-15 minutes (granted I don't get it until I receive the monitor).
