Triple Monitor Docking Station - Apple Community

The Mac supports Multi-Stream Transport (MST, multiple displays on one cable) with a maximum of TWO modest-sized displays ONLY on Genuine ThunderBolt Cables connecting to a Genuine ThunderBolt device [dock or display] as the first device.

So, not support the Dell U3223QE with macOS.

Thank you for the clarification. That was my understanding also.

Thunderbolt doesn't use MST. The Thunderbolt controller in a Mac gets two completely separate 4 lane DisplayPort connections from the GPU. The two DisplayPort signals are tunnelled over Thunderbolt to Thunderbolt controllers in downstream Thunderbolt docks or Thunderbolt displays where the tunnelled DisplayPort data is converted back to DisplayPort. At no point in the chain is MST required. The signals can both be SST.

In Windows or Linux, the signals can be MST or SST depending on the downstream DisplayPort device so in theory you could connect a dozen displays using two separate MST hubs connected to a Thunderbolt dock or hub. I don't think any GPU can do a dozen displays so you would need to be able to connect two GPUs to the host Thunderbolt controller which is possible when the Thunderbolt controller has accessible DisplayPort inputs such as in some PC motherboards or with Thunderbolt add-in cards.
 
I got my u2723qe. I really like the picture quality for the price. I’m really happy for lightroom.

My biggest disappointment is the lack of MST support. I’ll need to use a second cable for 2nd monitor… not a deal breaker though
 
Got my 2nd U2723QE today (ordered one with 5% cashback on Rakuten then they increased it to 15% so I ordered another and am returning the first for the extra 10% off).

Very nice display - I'm actually running it at the 1080p scaling and have found it to be plenty of real estate when I am also using my MBP display. I even have my Lenovo M14 plugged into the other side for fun.

Definitely nice blacks when running HDR demos on YouTube - I haven't dug into the settings much, just bumped the brightness up to 80%.

Get a Thunderbolt dock. Nice single cable solution. I use a USB-C Pro dock from Caldigit (it's Thunderbolt 3) and it provides 2 x 4K 60Hz outputs. Works perfect with my Apple Silicon equipped 16" MacBook Pro :)

do you have the exact model?
 
I have an older Targus TB3 dock that I picked up 2nd hand that has worked great with my MacBook, although I haven't tried it on multiple displays. Just 4K 60hz over DisplayPort. Single TB cable from the dock to the MacBook provides gigabit ethernet, display and all the USB junk I can plug into it.

Thunderbolt™ 3 DV4K Docking Station with Power (Space Grey)

Connect to dual, extended displays on any Thunderbolt™ 3 host device — and charge your laptop — with the Thunderbolt 3 Docking Station.

In theory the Dell can replace this, but then I have to route the any cables that currently go to the dock up my monitor arm to the display. Currently it's just the power and display cable up that arm, and a TB cable up the other arm to my laptop tray.

So we'll see how the cable management goes once I mount the Dell on the arm and route some cables. I'm sure it will be fine and better than having the dock sitting on my desk.

out of curiosity, for people who have the monitor, which HDR settings did you set?

The choices are : Desktop, Movie HDR, Game HDR, DisplayHDR 400 and OFF

I'm not sure what I should choose.
 
Can anyone tell me which setting I have to choose with the joystick in this monitor?
When I selected USBC-90W auto I had no picture. The USB-C cable was connected to port 5: USBC 90W.
TIA

The best setting for playing HDR content is "DisplayHDR 400", this setting provides a calibrated HDR color reproduction. However it is good to know that the peak brightness is only around the 450 nits (as it is a DisplayHDR 400 monitor), so highlights won't be as detailed as on higher tier HDR monitors like DisplayHDR 600/1000/1400. I think that's what RabidMacFan means.

Can someone tell me if the USB-C cable provided with these Dell monitors is compatible with the Mac Studio? The screen remained black.

Works fine with my MBA M1, so it should also work with the Studio. It's just an ordinary USB-C interface.
 
Noob question guys. I tried gaming with this monitor on my PC.

But my PC isn’t powerful enough to game at 4K.

So I tried playing at 1080p and 1440p and to my surprise, the picture quality was VERY good.

I remember when not using the native resolution on my old cheap monitors, it would end up in a blurry picture.

But with this Dell, wow, * almost * as good as native res.

Is there a reason?
 
Just got one of those U2723QE and the issue we're seeing is the ethernet port when disconnected, the next time you connect to the monitor, you won't have an active network connection. You need to unplug the cable from the monitor to refresh it. I've seen with Windows users they can update the Realtek driver and that fixes it for them but macOS users don't have that option.

Any ideas?

No driver needed both win/mac, check your eth cable.
 
The default setting for usb-c prioritization is “high resolution”, that means the data transfer protocol limited in usb2. When you plugin the C cable you will be noticed by the screen popup message. Switch to “high data speed”, you will get usb 3.1 10gpbs speed for all USB-A/RJ45 Eth ports.

But I suppose you lose performance for your monitors? Maybe you can’t do 4K/60hz?

The documentation says nothing about it when you change this setting. If it exists it must limit something

It limits you to two lanes of DisplayPort. If it's HBR3, then you can still do 4K60Hz but only at 8bpc unless DSC works.
