Don't be. I have the U3223QE and text is absolutely sharp at 2560x1440. I have my monitor 85cm away and I cannot see pixels. But I did play with Apple font smoothing a bit. On the M1 Mac mini I have it set at 1, and on the Intel Mac mini 2018 I have it set at 0. Believe it or not, Intel and M1 process font smoothing differently.
I have a 27” 1440p monitor now so I wanted quite a lot more screen real estate. I got the chance to use a 32” 4K Lenovo monitor recently and loved it with my Windows 11 laptop. It was very usable at 100% scaling if you zoomed in about 10% in the browser.

2560x1440 in macOS wouldn’t cut it for me.

The "looks like 2560x1440" option is the 2nd option. There is still 3 options above that one that give a larger desktop area (with objects rendered smaller).

As shown in this screenshot of the U2723QE that I have:

So you can certainly gain access to more screen real-estate while still maintaining high fidelity.

I have been using the U2723QE for about 2 weeks now, and while it's a great monitor, I ended up returning it in favor of the Apple Studio Display. The one huge advantage the Apple Studio Display has over the Dell is the glossy finish, compared to the matte display on the Dell. Images on the Studio Display are SO much more vibrant than on the Dell display. It simply pops, and the Dell display looks dull in comparison.

Perfectly valid rationale, it's difficult to get desktop monitors that are glossy these days. Very few manufacturers do them and what you say is completely true. I'd probably pick glossy over matte if the anti-glare coating was the same as on the Apple displays which I consider quite acceptable.

Yeah I was aware of that but after seeing the video below it now appears that there’s a performance hit when using resolutions that aren’t 110 or 220ppi. I won’t be doing anything that taxes the GPU so it should be okay.

I’m in the UK and my U3223QE had an estimated delivery date of 25 July but it was shipped out yesterday.

Kinda nervous about this scaling stuff in macOS though.
Good to know, but I'm afraid of getting stuck

He mistakenly said there's a scale up and scale down process contributing to the performance loss. There's no scale up. The GPU does one transformation - from 5K down to 4K. Everything else is up to the application.

That video would be better if it gave same numbers. Some benchmarks with the following variables would be interesting:

Using displays (smaller displays have fewer pixels for the GPU to output but that doesn't really matter because a good scaler has to look at all the source pixels of the framebuffer defined by the display modes)
- 1080p, 1440p, 3K, 4K, 5K, 6K (some displays can accept custom timings that make them behave like a display of a different size see you don't need one of each display for a test)
Using non-retina modes (usually a user would use a display mode that is not larger than the display resolution - 1440p on 1440p display but not 4K on 1440p display)
- 1080p, 1440p, 3K, 4K, 5K, 6K
Using retina modes (retina modes makes objects 4 times larger, but once an object is drawn, it usually doesn't have to be drawn again unless it is moving)
- 1080p, 1440p, 3K, 4K, 5K, 6K (a 6K retina mode is actually 12K pixels wide - usually a user would use a retina mode that is smaller than the display resolution - 3K HiDPI on 4K display but not 4K HiDPI on 4K display)
Using different refresh rates (a lower refresh rate could have more performance since the GPU would be scaling fewer pixels per second)
24Hz, 30Hz, 48Hz, 60Hz

There's probably no such thing as a 3K display but you can just create a custom 3K timing 3008x1692. Scaling that is done by the display instead of the GPU will not have an effect on performance.

In the video, the user went to a 1440p display because a 4K display had low performance doing 1440p HiDPI. If you had a 4K display that can accept a 5K timing, then it could perform better at 1440p HiDPI since the GPU wouldn't need to do the scaling? My Acer XV273K 4K display can do 5K60 but only up to 8bpc. Do these 4K Dell displays (or any 4K display) support 5K input using DSC? Maybe it's not the scaling that causes the problem - maybe it's the quadruple number of pixels. The suggested benchmarks would determine that.

There's no way to do custom timings on M1 Macs so there's no way to get a 4K display to accept a 5K timing on M1 Macs unless you can spoof the EDID but I don't know of an inexpensive device that can do that for DisplayPort connection.

Please apologize if I'm off topic but in my country (Italy) both monitors are impossible to find, both Amazon and Dell.
On Dell site the delivery date is estimated for July!!!
All the Ultrasharp monitors have long waiting list...
Do you have any idea why is this possibile?
I'm in Italy too and I've decided to go with the LG LG 27UP850 instead. I decide to do that because the price difference (400 the LG vs 850 for the 27" Dell) is too much for me.

I'm really happy with the decision. The LG is really good for me (I usually use an iMac 5K or a MBP 16" 2021 that both has incredibly good display). I was undecided for a really long time and I made the decision to save some money and the decision, which for me being very selective with screens could be wrong. But it was not, I am very satisfied with the LG and unlike the dells, they are immediately available.

Sorry if this is OT but I think that for some user the Dell delivery times are too much to wait and also I want to share my personal experience to help someone else that has the same doubts. Thank you

Hey there. I've been following this thread for a while and I'm wondering if anyone is having any issues with those Dell monitors when connecting to a m1 mac mini (not getting RGB scheme, screen flickering, not waking up from sleep etc.)?

I used to have a Dell U3219Q but i sold it because it doesn't fit into my colour scheme at home + i wanted to try out Ultrawide. So i got the Dell U4021. I will return it because of scaling issues + the edges are to big for my taste (looks like a Studio Display).

I want to buy a Dell U3223 now because the Dell (at least the Dell U3219Q) was one of the few displays out there which (in my experience) had 0 troubles with my Mac Mini. It didn't wake up randomly while the Mac was in Sleep Mode, i had 0 issues with the picture and (the most important thing) the scaling was absolutely superb for my tasting without any third party software whatsoever.

So in my thinking: The Dell U3223 should perform exactly like the old U3219?

anyone having this monitor uses the "kvm" like feature? I plan to switch between my PC and Mac and I want to use the ethernet port on the monitor for my mac.

My question is, what happens to this port when you switch? I understand this monitor has a usb hub so I suppose, when you switch between machine, all the usb devices disconnect from the original computer than reconnect to the one you switched.

Is is still the case with the ethernet port or it's like a mini integrated builin switch in the monitor? Because if the etherport disconnect too when switching, there is totall useless...all my apps will disconnect from network every time I switch. If it's the case, I'll need a dedicated usb-c/etherport on my mac too.

I have the U3223QE connected to my M1 Mac mini, and there are no problems at all. No problems with RGB, no problems with screen flickering, and no problems from waking form sleep.

I have not tested the ethernet port, but I think this is the idea - everything will be switched, including the ethernet. So far I have tested switching all USB devices... and on the Mac, if you have storage devices connected via the monitor hub, then you will get the "Device not ejected properly..." warning when you switch.

In that case, beside keyboard and mouse, it’s kind of useless in KVM mode

I need a new monitor. I've read this entire thread and it seems like the 30" model is a good choice. You should be able to use it at native resolution without scaling, and you get more pixels with it being a 1600p monitor.

LG doesn't seem to have a comparable model.

Am I missing something about this monitor?

I have a macbook (no ethernet port) and a PC.

I wanna switch between the 2. It means that every time I switch, the ethernet will disconnect from my mac and all my file transfers or apps using network will disconnect.

Same with me - I had a U2720Q that wouldn't show RGB regardless of what I tried, but the U3223QE has been fine from the start. I still haven't had a look at the Apple Studio Display yet, but I'm really enjoying the 31.5" vs 27"

I agree with you, I understand everything switches, you can use a mouse and keyboard at once but for ethernet is totally different, the user must decide if eth must switch.

I read the u3023e users guide but no setting is decribed, maybe who owns the monitor can browse the settings menu to search if some special option is available for the ethernet

Yes I read the manual too, saw multiple youtube video reviews, nothing about that. I'm supposed to receive it on June 1st. I'll try it as soon as I can

Build quality of the display bottom in general is not best. My (meanwhile returned) U2723QE also had some irregular gap dimensions at the bottom, but no such tape stickings.
I know the U2720Q had many problems with this.
I would return this device as this is not the build quality i expect from a 780€ device (listed price for 27" in Germany).

This is already my second U2723QE. My first model hat pretty bad backlight bleed and foam sticking out on the exact same place. I´m a bit scared to replace the monitor a third time and getting a worse panel again.

My U2723QE also had bad backlight bleeding in the lower left corner where the USB ports are and really bad IPS glow.
How about the backlight bleeding on your replacement. Is it it better? What Rev. did you get A00 or A01?

I got an A01 February 22 again. The replacement has zero backlight bleed in a completely dark room. I was pretty surprised.

I don´t know if I got a refurbished model. The monitor itself seems completely new, but the usb-c cable looks pretty worn.
