Dell released their newest Ultrasharp model ,U2723QE, U3223QE Ultrasharp monitor

Just wanted to ask related to the U3223QE, has anyone tried to use it with BetterDummy? I had good experiences with 34 UW devices + BD before to remove blurring, but it would be quite helpful if anyone would have had tested it before I go and buy the display. :)
 
The U2332QE is a 3840×2160 screen and gets the HiDPI/Retina modes out of the box. There's no need to mess with BetterDummy unless you're on an original M1 Mac and want to run a scaled HiDPI mode higher than 3008×1692.

Oh, good to know that, thank you. I guess I got confused by one of your earlier messages.
I find this acceptable even though I easily notice the blurriness introduced by scaling compared to the 27" 5120×2880 218 ppi monitor running at pixel-perfect 2560×1440 that sits next to them.

So this means that MacOS can treat a 32" 4k monitor without noticeable blur on text (eg.: what you get on a 34" UW by default), and you only observed the blurriness because you had a reference 27" 5k display next to it? In this case this Dell unit looks like a nice addition to my HO days.

The only way to have pin-sharp text on macOS on a 3840×2160 monitor is to run it at the pixel-perfect "Looks like 1920×1080" setting. Any other setting introduces some blurriness due to the way macOS handles non-integer scaling.

What I'm saying is...

1. I can notice that blurriness compared to a 27" 5K display running at pixel-perfect "Looks like 2560×1440". But it's not so bad as to annoy me.
2. Even with the blurriness, it still looks a lot better to my eyes than a lower-resolution display running at a non-scaled mode, such as a 34" 3440×1440 ultrawide.

If you want to get rid of the blur from font smoothing you can try this app...

I considered 27UP850 as well but went with U2723QE. My thought process:

Why U2723QE is better?
- IPS Black panel with doubled contrast ratio.
- More and superior ports as USB hub. (I think 27UP850 only supports 4K60Hz with USB 2.0 speed?)
- Built-in power supply.
- Slightly more DCI-P3 coverage (98% vs 95% of LG)
- Better design (to my eyes - not a fan of LG's curved base).
- Displayport chaining and KVM (in case I need to use it with PC)

Why 27UP850 is better? (and why they don't matter as much to me)
- 96w power delivery over USB C (compared to 90w of Dell) - the difference is really small.
- AMD Free Sync - I don't game.
- Built in speaker - I heard quality is mediocre.
- Lower listed price ($550 vs $780) - U2723QE is now on sale for $625, and Amex is offering $120 credit (valid before Apr 2), I actually got U2723QE at around $500.

For me the biggest downside of the 27UP600 (which uses the exact same panel as the 27UP850) was the horrible IPS glow. The U2723QE is much better in this regards.

i'm also interested in buying a U2723QE but i worry about the reviews that show strong backlight bleeding in the lower left corner where the USB port is. Is that a general problem?
I also would like to know whether the LAN port supports 1Gbit/s connections with full speed.

Honestly backlight is much better on U2723QE than many other competitors. It's almost unvisible with daylight and barely visible with artificial light and only with very dark pictures.
A perfect backlighting is not possible within this price range, and it's really difficult to get even within the higher range.
 
Yes, but backlight bleeding also seems to depend on the construction of the case. My MBA M1 also has an IPS Panel with the IPS-typical low contrast and some IPS glow but it has no backlight bleeding spots.
I also have an old Panasonic IPS-TV with no backlight bleeding at all.
On the photos in the reviews of the U2723QE the spots are always in the same positions.

The ethernet port supports 10/100/1000....

Question to owners of the U3223QE or the U2723QE, are you using the USB hub on the monitor and does it work after reboot? apparently some users are having issues with the U3219Q
forums.macrumors.com

USB Hub not working on Dell Monitor w/ Mac Mini M1

Similar problem with Dell U3219Q and M1 Mac Mini (Big Sur, 11.6). Using only USB-C connection for Video and Hub. Only workaround is to disconnect USB-C AFTER booting and connected again, then the Hub works.

Thanks

Thank you!
So we have to decide between max. quality and max. network performance.
Anyway, i guess even 340 Mbit/s will be enough for most of my use cases.
 
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...
 
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.

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 I 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...
DSC06843.JPG

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.

I already ordered a U2720Q a few weeks ago, but unfortunately the build quality, or more precisely the fit of the display and frame, was so poor in the entire lower right area that a large gap was visible. In the gap, you could see something like a twisted seal. The screen was therefore returned. I was hoping that the build quality would be better on the U2723QE. The price is actually nearly the same for both here in Germany but i think the U2723QE was much cheaper in the past.

Mne went back - slight brightness flickering no matter what combination of cables and settings.
Thought I'd fixed it but it came back :(

Was a good screen apart from that.

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?

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.
