T14s(amd) and daisy-chain to 4k monitor (from fhd display)

2021-04-20, 13:25 PM

Hello to the users of Thinkpad (especially for T14s AMD 😂)

 

Currently, I am using a monitor with c-type connection, DELL U2421e.

I'm wondering setting up a dual monitor, by daisy-chain on displayport.

Is there any problem that the second monitor is 4K?

 

Thank you in advance for your great answer!

Hi 2joonh2!


Welcome to community forums

 

 

The laptop can support up to 3 external monitors via HDMI® (up to 4K @ 60Hz) or USB-C (up to 5K @ 60Hz)

 

Daisy-chaining is a feature of the display port. You might want to check if the feature is available on the monitor. 

For more information, you can refer to this link: https://www.displayport.org/cables/driving-multiple-displays-from-a-single-displayport-output/

 


Regards

Hello to Jwes_Lenovo, and great thanks.

 

Indeed, I've checked the availability of daisy chain at my monitor, thanks for remind.

Just for check, being said "3 external monitors ~ 4k at 60hz" means I can use upto triple 4k monitor setup?

(if it is, it would be awesome😂)

 

Thank you!

Hold your horses.  If you expect to be able to connect three 4K displays in a MST (daisy-chain) setup, you're probably in for  a big disappointment.

The psref usually assumes/describes  a setup of three displays connected to the system directly ( in this case 2x USB-C and one display connected to HDMI port)

 

In a MST setup, however, other details become more important, such as the supported DP version of the  monitors.

Two 4K displays that only support DP1.2 would be limited to 4K@30Hz in a MST setup.

 

Tech-Savvyness does not replace reading the fine manual.

Well thanks for the advice!

My monitor currently support 1.4 of DP, and after moment I have decided to double-set the same monitor(WUXGA) and organize it neatly.

I would remind it for getting right decision at the MST setup.

 

Once again, thanks for the great advice!
