I noticed that when I had it hooked up to my m1 MBA and my daughter's M1 Mac Mini. I did a lot of research and thought it was an M1 thing. I hooked it up to my Intel Imac and the flickering is way less. Still occasionally there but much less. I'm waiting to decide whether to keep or return it until I can hook it up to the Mac Studio. What computer(s) did you have it hooked up to?
A MBP 14

Now gone the ASD route, bit the bullet, took the hit, etc etc.

I have the same MBP as you and I'm thinking about getting the 27".
Which exact cable are you using, and can you confirm you're getting @60Hz with it (since the MBP offers only 1.2DP)? Thanks.
Hi,

I'm using one cable that I bought from AliExpress. Its specs says it can transmit 4k@60Hz, that in fact is available for all resolutions, despite the fans going crazy in the highest one. I prefer use 2560 x 1440

EDIT: I edited the message as it became invisible after I posted a link to the cable in AliExpress ?

Anybody had a chance to compare U2723qe to U2720q or some other UltraSharp model? Based on some posts, ComfortView Plus technology on the newer one makes picture a bit yellowish. I'm mostly concerned about the white tone.
I had the U2720Q and sold it once I got the U3223QE - the chance for a bit more screen estate and ’better’ blacks for very similar price. Bonus is that the U32 displays RGB without any trickery with Monterey - could never get the U27 to keep RGB setting on my M1 Mac mini. I’ve also just calibrated it with a SpyderX and it looks a tiny bit warmer than previously. I may try the SpyderX again at A different time of day to see how it goes.

spec:
98% DCI-P3
2000:1 contrast

Please, please... stop reiterating this nonsense! Backlight bleeding is there because people like you accept it!
I have owned a significant amount of IPS displays, from laptops to external monitor, over the past 15 years, even when this technology was not that good and popular. It's the first time is see such a horrible bleeding and IPS glow. The bleeding is the rare exception, not the norm and it's usually minimal. Here is massive, and problably due to how the panel is mounted on the frame by Dell, rather than an LG issue.

Below is a U2720Q vs U2723QE comparison, guess which one is which...
View attachment 1979722
Yes, the black on the 20Q is blueish, but where is the black on the 23QE? You tell me. Guess which one I'm going to keep? And guess how much more expensive the older 20Q is?

Please, cut this "but after all it's okay" nonsense. These monitors are NOT cheap and this level of defect shouldn't be there.
That U2723QE looks like a bad sample, which revision do you have, A00 or A01? The two Rev A01 I had were pretty good. I had also two samples of the U2720Q where one was like your sample, pretty good, but the other sample was much worse regarding backlight bleed. So panel lottery is also a factor here, not only design/build quality.

No doubt I got a lemon (A01, Dec 2021 - BTW the revision number is not related to the panel, I'm sure), but I don't seem to be the only one here. And it's hard to understand whether the few who kept it did it because it's not there or because they tollerate it, which is not the same thing!

Yes, the 2020 model also had its problems (tons of complains about the warped frame around the lower buttons, bleeding, etc.), which again shouldn't be there. Guys, how can you consider buying a monitor in 2022 a lottery? Did you pay with maybe, somewhat defective money? They send them out with these defects because it's only a tiny fraction of customers that complains, otherwise they wouldn't. I'm sure most of the bleeding it's not coming from defects between the layers of the panel itself, but rather tension between the panel and the outer frame. In fact, if you hold the monitor from the sides, the bleeding changes. This can and should be solved. There is no such thing as "all the IPS panels have backlight bleeding", or only grade A+ panels have no bleeding. And even the glow, yes it will always be there, but can vary wildly, from OK to crap.

At least Dell has easy refund and exchange so you could try for an exchange before deciding.

A tiny fraction of customers complain because most customers don't care much about frame gap and backlight bleed. I wouldn't have even noticed how much of a gap between the panel and frame if no one brings it up. And most people don't look at a pure black screen in a dark room. With normal room lighting, the backlight bleed is barely noticeable.

I'm not saying these are not problems. They can probably fix them - or better quality control - to make small amount of customers happy, but the price would inevitably go up and make majority of customers unhappy. (With a plastic frame, they probably have to leave some gap between frame and panel to accommodate panel shrinking and expanding with temperature change. They could also contribute to backlight bleed. I imagine metal frames like what Apple uses can mitigate the issues, which increases cost)

That said, I'm more frustrated with color temperature variation in different panels. I've gone through 2 panels and the difference is wild: one is super yellow compared to the other. This is particularly annoying in my dual display setup, but again I probably would be happy if I have a single monitor setup.

I was looking for new monitor and was very excited about new IPS-Black panels with promising 2000:1 contrast ratio, but after reading so many complains about quality control of U2723QE, I ordered S2722QC for half of the price.
U2723QE cost 730€ and S2722QC was 300€ on sale with extra AMEX offer in Germany.
27" 4K with USB-C 65W charging and 2*USB-A 3.0 ports.
1300:1 contrast ratio is absolutely fine for me, I really don't see reasons for regular user to pay double for U2723QE and deal with that terrible quality control of new IPS-Black panels.

I can watch movies on S2722QC with black bars even in complete darkness and they looks fine, without any extreme bleeding/glow.

Yes, U2723QE have few extra perks like extra ports or higher USB-C charging capabilities, but bad quality control makes it overpriced lottery with low winning chances and with very few real advantages for regular users.

Won't lie, you have me intrigued to swap models for 50% off. I have zero desire for the hub, but the contrast for creative work was a pro. Tho how much is 35% deeper blacks really worth?

What other differences besides hub and IPS black? is that eye comfort offering on the QE a nice improvement over the QC?

Awesome thanks !

So to summarize? The darker blacks aren't noticeable but the colors are better on the QE? I do design work for a living, so color is important. But is it 2x price better?
I can tell colors are a little different. Since I don't do any color related work, it is not 2x price better for me. But if it's for design work (I assume color accuracy is important), I would bite the bullet and get the QE if your budget allows.

I thought S2722QC contrast ratio was 1000:1.
Rtings measured 1304:1 for S2722QC

Meanwhile U2723QE have only 1817:1 instead of declared 2000:1
https://forums.macrumors.com/thread...or.2333450/page-7?post=30856949#post-30856949

Since I don't do any color related work, it is not 2x price better for me
Exactly my thoughts.
And it is still absolutely suitable for hobby/enthusiast photo and video editing.

Hi everyone,

Did you guys had troubles to activate the HDR option on macOS Monterey? I have an U2723QE and I'm using a high quality (I guess) Thunderbolt 2 to DP port cable in my mid 2015 macbook pro 15". Nevertheless, no signal of the "High Dynamic Range" option within the display settings...
You have to enable it on the monitor first. Display > Smart HDR > (Desktop or DisplayHDR 400)
Only then will you see the checkbox in your macs display settings.

If that doesn't work, it may have something to do with the graphics card in your 7 year old mac. I don't have a 2015 MBP to try.

after read all this nightmare, that's why I'm tempted to buy the studio display, I don't say the studio display is perfect but... I don't have time to dealing with all that "issues" reported here and is the same thing with others LG and many others brands/models.

I forgot (sorry...): You're limited to 30 Hz even via DisplayPort because a 2013 MBP has DisplayPort 1.2, and these monitors require DisplayPort 1.4 to do "4K" at 60 Hz. So, it doesn't really matter whether you go for option 2 or 3.

This was the deal breaker for me. I have been holding out for a 4K 32” monitor for a while, to use with my (aging) 2013 Mac Pro, and I was picking between the Dell U3223QE and the LG 32UL950-W.

With both of them side-by-side the choice was easy...

The U3223QE was only giving me 30Hz 4K, whereas the 32UL950-W is giving me 60Hz. The LG uses a Thunderbolt 3 port, and even if my 2013 Mac Pro only has Thunderbolt 2, the LG is able to get 60Hz on DP1.2 - and that makes the difference.

On a subjective note; the LG looks way more uniform, and it is much more pleasant to read text on in 4K. The Dell may be a bit brighter, but that is less important to me, as my office is pretty dark anyways.

LG 32UL950-W for the win - I should NOT have waited a year for the Dell…

Yeah, 30 Hz is pretty annoying.

I wonder if it’s possible to convert four lanes of DP 1.2 into two lanes of DP 1.4 — I think the opposite is possible using a MST hub.

I also wonder if you can attain 60 Hz using an active DisplayPort 1.2 to HDMI 2.0 adapter and the monitor’s HDMI input. 4K60 requires 594 MHz pixel clock using HDMI timings, and the AMD GPUs in the 2013 Mac Pro might be able to do around 600 MHz.

TBH - I am more happy with the LG, and not just because of the Hz. The LG is just better to look at; text shows better, more clearly, and the uniformity of the monitor, and the colors - just a better experience.

If the Dell had a Thunderbolt port, and more consistent quality, I'd possibly reconsider.
