You've got some eagle eyes man. I use a 4K 27" scaled to 1440p. I still feel sometimes the texts are too small to read from 75~80 cm distance. 50cm would be a perfect distance for me in this situation. But I want some space in front the monitor so I can write from time to time. Eventually I choose to scale to 2304x1296.
No, not really eagle eyes, I have a prescription... I increased the fonts of Finder and any other app I use and that supports it to 16 points. The System preferences are still a bit small, but I do not see the pixels. All I see is a sharp display, with a plenty of real estate to arrange a lot of windows... I don't like multi monitor setup, and I have had 3 at one time.

Edit: just to be precise, I measured my sitting distance, my eyes are 78cm from the top edge of the display.

The two I ordered come with 1m USB-C cables. I’m going to need a 2m for one of them. Any suggestions for a 2m USB-C cable that will work correctly for the display connection. I don’t want some cheap-ass cable that ends up giving me grief.

It sounds like I cannot dasiy-chain them on my M1 Max MBP.

I had an issue with my brand new Dell U3223QE. The display was going black for a second at random intervals. I was going to post about this, but then I realized I wasn't using the original cable that came with it.

The setup diagram had two charts for laptop and desktop:
- Laptop: connect to laptop using USB-C supplied cable
- Desktop: connect via DP cable and USB-A to USB-C for USB upstream.

But my Mac mini does not have a DP, so I connected with a 3-rd party DP to USB-C cable and USB-A to USB-C for USB upstream. I was getting intermittent connection breaks at random.

So I changed the DP to USB-C with the supplied USB-C to USB-C cable an no more connections breaks.

Question: Do I still need the USB-A to USB-C for USB upstream? Or does the one USB-C cable connection handles all? Currently I have them both plugged in, and all is good, but just wondering...

And BTW, I find this display amazing, with all its features it is invaluable compared to the ASD, even though it is "only" 4K.

Update: I increased the viewing distance to the monitor to 86cm as directed by our ergonomics department to account for viewing angles and to prevent repetitive neck/head movement for repetitive stress injury.

I don't mean to offend anyone, but sometimes I wonder if the no-question-asked return policy is being abused when people (1) order something just to play with it; (2) order two or more different products and keep one of them after comparison; and (3) order multiple samples of the same product and keep just one sample after comparison.

I wonder if this is one of reasons why they are sending out open-box items for customers who order brand new hoping customers won't notice, because they got so many of the returned items.

I’m also thinking about getting a VESA mount on the back of my desk (it’s 1/4” glass), to mount the two displays and dispense with the stands. Any recommendations? I don’t have a budget, and willing to get spendy if there’s a compelling reason for it (i.e. functional, not coolness).
To answer my own question, I ordered a Vivo articulating mount for two monitors from Amazon. The most similar Monoprice one is about the same price, but unavailable anyway.


I have a glass top desk so on Vivo’s advice (customer support answere dmy question about it in about an hour), I also ordered this reinforcement plate: https://www.amazon.com/gp/product/B07NNVJHRY

Yes and No...

Not serious if selling next customer not the brandnew stuff... Amazon does it often here now... should be marked as return with some discount...

As you can not see all these monitors in real life in a shop... the only way to compare is the workflow of some customers... order all - decide in real life for the one best suited your needs. Adding the often missing quality control by manufacturers...

Anyway some patience is needed too by customers...

It is 400 (brightness) Dell site U3223QE
Also it is interesting that:
"World’s first 27" and 31.5" 4K monitors which allow daisy chaining of an additional 4K monitor at full resolution via USB-C—enabled by Display Stream Compression (DSC)"
Will 2 of them daisy chained work with M1 Macs with no adapters needed then?
This is kind of misleading. The LG ultrafine 4K can do this. They're ignoring it because its 24" instead of 27".

Correct. The 23.7" LG UltraFine 4K only allows daisy-chaining when using a Thunderbolt 3 connection to the computer, not when using a USB-C connection.

Dell's monitors do it via USB-C using DisplayPort's MST feature, which macOS doesn't support.

It sounds like I cannot dasiy-chain them on my M1 Max MBP.
Correct. macOS on Apple Silicon doesn't support MST at all.

I’ll return my as my contrast ratio was only 1300-1400 and dell was stating that it was 2000.
Maybe I have a bad example I don’t know. I might try an other one :)

I read that you have a Rev A00 sample. I had the same low contrast ratio with two A00 samples, one around the 1350:1 and the second 1650:1. Rev A01 gave much better results with around the 2200:1. So try to get an A01 when you exchange it.

Question: Do I still need the USB-A to USB-C for USB upstream? Or does the one USB-C cable connection handles all? Currently I have them both plugged in, and all is good, but just wondering...
That depends on what speed you want the USB ports of the Display to work at (480 Mb/s, 5 Gbps, or 10 Gbps).

You have an Intel Mac mini 2018 and an M1 Mac mini. Which one are you connecting to the display?

With just a USB-C cable, you are either using 4 lanes of DisplayPort with USB 2.0 or two lanes of DisplayPort with USB 10Gbps. The display has a "USB-C Prioritization" option to switch between the two modes.

The 2018 Mac mini can't do 4K60 with only 2 lanes of DisplayPort.

The M1 Mac mini can do 4K60 with 2 lanes of DisplayPort if DSC is working. M1 Mac mini supports HBR3 link rate, so you can get 4K60 without DSC using 8bpc but HDR requires 10bpc. Maybe someone here can tell if this is working correctly (2 lanes DisplayPort, DSC, HDR, USB 10Gbps)

The Mac mini's have USB 5Gbps type A ports. For 10Gbps, you'll want to get USB from the Thunderbolt ports.

The description of the USB upstream selection option seems to indicate that DisplayPort from USB-C cannot use USB upstream from other USB-C port? In that case, you should find a USB-C to DisplayPort cable that works. Then 10 Gbps USB can come from Thunderbolt port and you get 4 lanes of DisplayPort.

Got a new rev00 and it’s 1600 that’s good as 2000 is like everything just marketing and you got lucky I’m guessing.

The new one have better picture over all so I’m good. And the calibration is perfect also I have no ips glow or similar so this is a keeper.

What was your cd/m2 during this reading?
Also, what meter and software did you use?

First of all, sorry for my poor english.
I read all your posts in this thread and decided to give my opinion after I received the U2723QE (A001 January 2022) today.

1. The quality control of Dell is pretty bad. My unit had a few minor scratches on the back and foam coming out on the edge of the display. After thinking it was residue from the factory, I removed it. Now the standby-led shines through the minor spot missing the foam.

2. The blacks on the new IPS-Black-Panel are horrible, especially on the lower left corner. It has backlight bleed AND IPS-glow more than I have ever seen on any monitor in this price range before. On many spots the blacks are looking really grey (included USB-C cable, Night Shift turned off). I tried the P2723QE before, which I returned for the U2723QE. It had no IPS-glow or backlight bleed and the blacks looked way better.

But there are not only negative points. I really like the color of the display, the design and how many ports there are. Unfortunately there are no other monitors on the market which include a minimalistic design, ergonomic stand, color coverage and 90W USB-C Power Delivery for this price.

I would really like to hear your opinion and thanks for reading.

Well, IPS glow is unavoidable it is the nature of IPS technology. Backlight bleed is another thing. My U3223QE is Rev A00 Nov 2021, and has zero backlight bleed, and of course, has IPS glow. I find that, actually, the black levels to be pretty amazing. Compared to my old Dell P2715Q. Also the display is pretty bright, I cannot stand it more than 75% brightness. If you are expecting to view this in pitch black room and not see the IPS glow, then you will have to adjust - IPS technology will not provide that. Of course if you have bad black light bleed, return it. Another thing - any try to photograph the display black levels results in a completely overblown image, and it is not realistic.

Question is whether you see, in normal daylight or a lit room in the evening: 1) The IPS glow; 2) The backlight bleed.
If you don't see them - just forget about these things and enjoy.

So to sum it all up, what is the difference between A00 and A01? Will the casual user (office user) notice a difference?

From what I can tell, A00 has much warmer color temperature. And Degrader here measured lower contrast ratio in A00, which I doubt will make any difference in daily use. You might notice the yellowish tone in A00 if you have multiple monitor setup like I do and don't want to manually adjust.

But if you set the a00 to sRGB, p3 or rec 709 it’s factory calibrated and no yellowish.

My a00 (two) was not yellowish

So from my findings when I have gotten two displays is with MBP 14" M1 Pro as a source with USB-C cable.

Factory calibration?
The profiles that are factory calibrated is sRGB, Rec709 and P3 no one else is it but they are still kind of good. And you need to download the .icc files from Dell to get the best picture of the profiles. But even the "standard" one that get's created in macOS for the display are good.
So if you don't have a calibration device like colorimeter or similar then just download the .icc profiles from Dell and select the profile that you want to use and don't forget to change it in the displays OSD also.

My two displays with 3 months difference in manufacturing date works the same with RGB control that are proving that the displays in fact are factory calibrated.

Brightness
The whitepoint are drifting a little when you adjust brightness, not much but a little and are still inside tolerance (under deltae2) What I have done to "work" with that is that I did set the RGB at 71% brightness and then I did profile the other options like 50% etc. I have specific level och cd/m2 that I'm working with depending on the light in the room so for me it's easy to fix and work a round. But I don't think a regular user will se the difference.
You can get 380-400 cd/m2 out of the display at max. For me it's to high ofc as I can adjust the brightness in my room but I guess it's good for office work.

Contrast
Contrast should be set two 75% if you set it more you will clip white. The contrast ratio is around 1500-1600:1 and my guess is that Dell the read the contrast ratio with brightness at 60-80 cd/m2. Sure I can work with 80cd/m2 in totally dark room but it don't happen often.

IPS glow etc?
I have not notice any and no I have not taking a picture of the display as all displays are showing IPS glow. Keep in mind that I had two of this and non of them had IPS glow that I can see anyway.

Overall picture?
It's great! You need know that this is kind of a budget display in the pro segment and if you look at the price it's good and for day to day use is great. I'm satisfied with my buy and I'm thinking of buying one more to use two.

I connected my MacBook via USB-C to the U2723QE. Is it normal that the first USB-Port is not working/giving power?

It's been 2 weeks, still no replacement. Their customer service is unreal bad...

After 2.5 hours of talking with Dell, they are now quoting me end of month...

I am torn on not wanting to give them my business and realizing there aren't many options like this out there.

Can anyone direct me to an alternative? I do graphic design and need good color. Willing to buy a fancy gaming monitor if it ticks all the boxes.

Well, you have to be mindful of the situation in the world, like with the chip shortage, the pandemic lock-down etc. I was lucky to pick the ONLY one available unit in my country. So these things are normal when considering the whole state of the world right now and the production limits in China.
