How to Setup a Daisy Chain with the EV2457

With a daisy chain connection, multiple monitors can be neatly connected to each other in a row. This guide will explain how to connect monitors using a DisplayPort daisy chain, and compatibility with various PCs. Rest assured that your daisy chain environment will work for you.



Q1.  What is a daisy chain?


Instead of connecting each video signal cable from the monitor to the PC, several monitors can be connected to a PC by plugging the PC into monitor 1, monitor 1 into monitor 2, monitor 2 into monitor 3, and so on, like a daisy chain. By using a daisy chain, several monitors can be connected to a PC with only one output terminal, rather than the number of connectible monitors being limited to the number of outputs on a PC.



Q2. What type of daisy chain is supported?

  The EV2457 supports the DisplayPort 1.2 MST (Multi-Stream Transport) daisy chain. A DisplayPort 1.2 MST input and output terminal is installed on each monitor.



Q3. What’s needed to run a daisy chain?


The following four items are necessary.

1. PC

  • GPU: DisplayPort 1.2 MST compatible
  • OS: Windows OS

macOS does not support daisy chain

2. Linking monitor(s) (serving as display unit(s))
EV2457 (DisplayPort 1.2 MST input and output terminal)

3. Standard monitor (serving as the final monitor in the chain)
Any monitor with a DisplayPort input terminal (DisplayPort 1.2 MST compatibility is not necessary)

4. DisplayPort cable (the same number as the number of monitors)



Q4. Up to how many monitors can be connected?


The maximum number of monitors that can be connected depends on both the DisplayPort 1.2 bandwidth and GPU performance. Be aware that between the DisplayPort 1.2 bandwidth and GPU performance information below, the smaller value of each becomes the maximum number of connectible monitors.

1. DisplayPort 1.2 Bandwidth

The bandwidth of DisplayPort 1.2 is 21.6 Gbps, therefore the maximum number of monitors connectible depends on their resolution.

Resolution (60 Hz refresh rate) Maximum number of connectible monitors
1920x1080 4
1920x1200 4
3840x2160 1

When connecting more than one EV2457, up to four monitors can be connected. However the maximum number of connectible monitors may become three or less depending on GPU performance.

2. GPU Performance

Vendor GPU Product Maximum number of connectible monitors
(with DisplayPort 1.2 MST)
Intel UHD/Iris Pro Graphics 600 Series 3
HD/Iris Graphics 500 Series 3
NVIDIA GeForce 900 Series or later 4
Quadro P Series 4
Quadro M Series 4
AMD Radeon 400 Series 4
Radeon Pro WX Series 4
FirePro W Series 4

The GPU specifications and maximum number of connectible monitors is dependent on the PC and graphics card. For details, contact the vendor of your GPU.



A laptop screen also counts as one display.

Example of maximum number of connectible monitors

You can turn off the laptop's display in the OS display settings.



Q5. Can daisy chain be used on portable laptops?

  Refer to question Q3 and Q4, and/or see our compatibility information for more details.



Q6. How do I connect and configure daisy chain?

  See page 4 of the User’s Manual – Setup Guide supplied with the monitor.



Q7. Can a daisy chain signal be converted to HDMI or DVI-D?


It cannot. Excluding Thunderbolt 3 / USB Type-C, only a DisplayPort cable can be connected to the input and output terminal.



Q8. Can you create a daisy chain from a PC with Thunderbolt 3 or USB Type-C?


Although operation cannot be guaranteed, it may be possible to create a daisy chain from a PC with Thunderbolt 3 or USB Type-C if the following conditions are met. However regardless of the following, other compatibility issues may arise in each individual’s device.

  • PC with Windows OS (masOS does not support daisy chain)
  • The USB Type-C port supports DisplayPort Alt mode
  • The GPU supports DisplayPort 1.2 MST
  • The monitor is connected to the PC with a USB Type-C – DisplayPort cable
