Dell U2723QE Daisy Chaining Guide 

Glad I could help!

@After10AM, thank you for the info. What type of laptop are you running?

Is Mac or windows?

Thanks!

@Kulturjunky, No worries at all.

You're welcome!

No worries at all, happy to help!

Would love to hear if this is possible as well.

No worries at all, happy to help.

@opuofbengal5935 No worries, glad it helped

Hi @spitsparrow, no clue regarding MST, however I suggest you read the following guide: www.dell.com/community/Monitors/U2723QE-two-MST-daisy-chain-hub/td-p/8307918

I haven't had the same issue. Are you using the USB-C port or Thunderbolt port on your laptop?

Did you find resolution? It's probaby the usb-c cable. 10gbits included with the monitors. Wondering switching to 20gbps changes things or not. 2 UHDs need Thunderbolt cable.

My workaround is to now use the highest resolution on my two monitors. That way I am able to set them to 60hz. I am using a thunderbolt cable and the correct port.

good question did you ever figure out how to get 3 display working off that way

@@AD-hs4cw I did not get monitor setup sadly, I invested in a stock bot to generate passive income instead. Try with chat gpt maybe, should maybe get you results.

We've had a couple of customers confirm that the daisy chaining does work with MBP's. Not sure about a 2019 Intel though.

Same here.. did you find out the solution?

Macbook's do not support the Daisy Chain function. You need a Windows computer for that functionality.

@@granttaylor8179They do but via thunderbolt only, not usb-s/DP (ie you can’t daisy chain these monitors on a Mac!)

Glad we could help!

Mine I connected the second monitor, a U2518D, setting the input as Auto. It's got 2 big DP connectors and it worked on one of them but not the other one. If that helps. If you have the master monitor already connected to USBC, when you plug the second the right way, you can hear a noise from laptop to indicate the new device found. Then press the 🪟 key + P and select the extend. It'll show all the monitors.

Hi @FrancisWong, not sure about that one. Does the menu on the monitor show multi-monitor support?

It should work, I've done it with the U2518D

I am having the same issue. I'd like to extend these displays instead of having them duplicated.

Same problem

Right click on the desktop anywhere and go to display settings there you would be able to identify the monitors after just scroll down and extend

Press key 🪟 + P and select extend

Hi @onthegamble, can you upload a photo or email us and we will see if we can help you. Cheers

Have you guys figured something out? have the same issue. Thanks ! :)

@@bomdiamedia2381 yes I called apple. MacBooks (all models including pro) cannot support one port for multi monitors daisy chained. One port for one monitor only otherwise it mirrors. However I found there is a work around where you can buy a display link hub and download the display link software and it supposedly works. I haven’t tried it, I’m now just using one port for one monitor until the newer MacBook pros support daisy chaining

I have the same issue. Have them working as Mirror but can't get extended to work.

@@andrewlawton6434 you can’t use daisy chain monitors with MacBooks yet. Each port is a one device output. There is a work around where you can get a display link hub and run display link software to get individual outputs but not 100% it works

@27ujjwal, Not sure if you can daisy chain with another non dell monitor. Will do some testing and come back to you.

Macs don't allow daisy chaining to work you have to utilize a docking station or another Type C or HDMI port if you have the M1 max it M2 MacBooks

Yeah nah

The Precision 560 may require more than 90 Watts for charging.

Have you tried running either DP into both monitors or USB-C into both monitors?

Macs can only daisychain via thunderbolt so these monitors will not work (I found this out after purchasing 2x U2723QE’s for my MacBook M3 max! 🤷🏻🤦🏻‍♂️

Hey. So I managed to get the monitor sync turned on on both monitors when the usb-c cables from both were plugged into my laptop. Once that was done I connected the DisplayPort cable from my Master using the DP Port with 90w into Slave DP 90W Port. Then I removed the USB-C port connected to my laptop from the slave, but as soon as I did this only the Master monitor worked and I was getting a no connection signal from the slave, until I re-pluggged it back into the laptop. I'm guessing that if this works I just have the Master connected via USB-c to the device, (my laptop), and then the 2 monitors conected via the DisplayPort cable? Can you please help me figure this out. Thanks so much.

One final bit of info...this is the monitor I'm using. Dell UltraSharp 27 4K USB-C Hub Monitor- U2723QE.. When I look at the back of my monitor the DP port with 90W is only connectible with a USB-C cable, the Display Port Cable slots are either side of that. So I'm not sure what to do about that, as there is no 90W DP port?

Thanks for your comment. We've seen a customer use 1 thunderbolt cable between the two monitors to work successfully however I've personally never gotten it to work. Where are you located? You may have a region specific monitor that for some reason may not allow it to work properly.

Hey@@RonaRigs thanks for getting back to me. I'm based in the UK.

@@RonaRigs I have tested and this would only work if I used Thunderbolt 4 cable from master to the laptop/pc and thunderbolt 3 from master to slave. It won't work if I use Thunderbolt 3 cable from Master to laptop/pc. Hope it helps :)

You have to have the monitor actually connected to your device first. Alternatively download the Dell Display Manager

Did you ever figure this out??

Are you plugging the DP cable into the input that shows a DP image with an arrow out?

Macs do not support this Displayport fiction.

Not sure, will do some testing and let you know.

I tried. It will just duplicate the image from the master. It doesn't shop up as a screen on it's own.

@opuofbengal5935, thanks for clarifying

Daisy Chaining will not work on the Mac.

@@granttaylor8179it does work I have a 2021 M1 Pro and a u2722de monitor with a asus monitor daisy chained with thunderbolt 3 usb c cable. Works flawless

Macs do not support daisy chain Displayport mode.

I don't believe so.
