Intel i5-13400T DisplayPort Daisy Chain for 3 Monitors (1440p)

Hello Intel Support Team,

I am considering using the Intel Core i5-13400T with Intel UHD Graphics 730 for an operator room setup. My plan is to connect 3 monitors (each at 2560x1440 resolution @ 60Hz) using DisplayPort daisy chaining with MST (Multi-Stream Transport).

My questions are:

  1. Does the Intel UHD Graphics 730 integrated into the i5-13400T support DisplayPort MST for daisy chaining multiple monitors?
  2. Will the UHD Graphics 730 be able to drive 3 monitors at 1440p @ 60Hz simultaneously over a single DisplayPort output?
  3. Are there any limitations I should be aware of, such as total bandwidth, refresh rate, or driver support?

The monitors I plan to use have DisplayPort 1.2 MST support.

Thank you for your assistance!
Best regards,

RGB color model means 8 bits per color component (BPC) by default these days. Like video timing, it adds to the bandwidth requirements and that's why I included it.

CVT-RB = Coordinated Video Timing - Reduced Blanking (from VESA = Video Electronics Standards Association)

 

As a user, you don't need to pay much attention to this. It depends on the display device. But if you buy a standard monitor like they are currently in the market, it will definitely support RGB 8-bit. RGB is essential for pixel-accurate rendering on monitors.

 

Your suggested source device: Lenovo ThinkCentre M70q Gen 4 - Product Specifications Reference

So this device "only" supports HBR2 (High Bit Rate Two), which is a maximum bandwidth of 21.6 Gbps. However, the connector is called DP1.4a because it supports Display Stream Compression (DSC).

 

According to the calculation above, you will pretty much need the maximum bandwidth we calculated.

 

Now it all depends on the monitors. Which ones do you plan to use (brand and model)?

 

The cheapest Lenovo monitor with DisplayPort Output for the daisy chain function is the Lenovo ThinkVision P24q-30.

In my opinion, this should work if you set the monitors accordingly in their On Screen Display (OSD):

  • Port settings > DP select
  • Port settings > DP daisy chain

 

But please ask Lenovo to be sure.

13th Gen processors offer DisplayPort 1.4a with the HBR3 protocol (32.4 Gbps).

 

2560 x 1440 @ 60 Hz RGB 8-bit (CVT-RB) = 7.2 Gbps

 

7.2 x 3 = 21.6 ... OK

 

You have rather to make sure that the motherboard fully supports the functions of the processor. Often the connectors integrated on the motherboard cannot do everything that the processor itself can theoretically do. The reason for this is that the connectors and the signal path from the processor may require components that do not fit into the cost calculations of some manufacturers.

 

The choice of motherboards with the socket 1700 is currently very large. Which form factor (ATX/µATX/mini-ITX) did you have in mind when planning?

Hi MUC,

 

Thank you so much for taking your time to answer me, great answer and explanation.

I'm currently looking at a pre-build office PC from Lenovo, ThinkCentre M70q Gen 4.

It's hard to find any information about the motherboard but it seems to be a Intel Q670 chipset onboard, do you think this will work?

 

Dumb question but how do I know the color depth (RGB 8-bit (CVT-RB))?

Hej MUC,

 

"So this device "only" supports HBR2 (High Bit Rate Two), which is a maximum bandwidth of 21.6 Gbps. However, the connector is called DP1.4a because it supports Display Stream Compression (DSC)."

Oh there's some things to think about when choosing CPU and screen!

 

The screens I have looked at are these, 32 inches monitors from Samsung.

24"/27"/32" ViewFinity S6 S60UD QHD Monitor LS32D600UAUXEN | Samsung Sverige

 

I have changed the setup to two 32-inch monitors instead of three, thank to your input I think that will work.

Thank you so much for your input in this matter, really appreciated.

 

Best regards Nordqvist
