How do you control a video wall using Samsung MDC?

Posted: June 13, 2012 at 1:14 pm   /   by   /   comments (81)

When you purchase a Samsung commercial grade LCD screen you probably received a CD containing the manual and a software tool called the Samsung MDC. MDC stands for multi-display screen and is a free Samsung software package that enables you to control a variety of different sources through the built-in RS-232C or Ethernet interface. So connecting your Samsung screens to devices such as a network of PCs allows for an easy exchange of data and information.

This tool is particularly useful if you needed to control multiple screens from a remote location or configure the settings of each screen from a PC. This post will discuss some of the settings you are able to configure from the software. But firstly, before using the software you need to physically connect the screens to a PC. This can be done either via a network or via a serial RS-232C cable. In this particular post, we will  look at setting up 4 screens together to form a video wall and connect them to one PC.

Page 56 of the manual has all the information you will need to know for the MDC set but the easiest way to do this is to connect the first screen via the Ethernet port to your network and then daisy chain the rest of the screens via serial RS232c. The first screen will need to be configured with an IP address and connected to your network. Once you have it connected to your network, then the next step is to connect the other screens. In order to do this plug the RS232 serial cable to the out port on the first screen and connect the other end to the “in” serial port. Then do the same to the two other screens. As an example you should have it cabled like below:


Now for the first screen you need to add an IP address to the first screen. Once this is configured then install the MDC software on the PC and launch the program. You will be asked whether you want to connect  to the screens via Serial or Ethernet. Select Ethernet MDC:

The application will then check the status of the screens and then display the information:

You can then control all the screen settings from this application. To get to the video wall settings you will need to click on Maintenance:

Select all the screens by selecting “Select All” and then Video Wall Control:

You will then be able to select the video wall configuration and change the relevant settings.

    Can you please share this software? Not delivered with my digital signage monitor and can’t find it anywhere on the net.
    Tried to contact Samsung but never got an response.
    Thanks in advance. 🙂

    Hi there!
    I have a ‘safety locked’ Samsung Syncmaster 320P which I am trying to connect to via the RS232C port to USB on the other end. I have been able to instlla the MDC Unified version 1217. I have set up a serial connection and am having trouble finding the monitor. Do you have any suggestions on what would help? Does the Syncmaster 320P work with this version on MDC?

    • September 7, 2018 at 7:55 pm EZY

      Yes the MDC software should work. It’s possible the RS232C to USB could be the issue. Have you tried any other device to make sure that the actual cable works?

  • August 9, 2017 at 3:30 am TK

    Hi! The link is not working. Is there any other way to download the installer?


    • August 9, 2017 at 4:02 pm EZY

      I’ll have to get Samsung to provide the new files. Will let you know when it’s updated.

      • August 9, 2017 at 4:32 pm EZY

        Thanks to the great team at Samsung, the link has been updated.

  • August 1, 2017 at 6:25 am Bobby C

    I have 15 LH46MVPLBB/ZA monitors. I have daisy chained the serial ports and connected the first screen to my computer using a USB to serial adapter. However the MDC is not recognizing and of the monitors. what am I doing wrong?

    • August 1, 2017 at 1:39 pm EZY

      Hi Bobby,

      On the Samsung Screen did you set it to use RS232 instead of RJ45.

      Another thing to check is to make sure the USB to Serial adapter actually works by connecting to a different serial device if you have one or even go through the local drivers settings and check if there is communication.

  • April 19, 2017 at 4:51 am Sam

    Is there a way to connect two screens without a source/computer? I guess the “source” would be screen 1, and screen 2 would just mimic whatever is on the first display.

    • April 19, 2017 at 8:14 pm EZY

      Hi Sam,

      I don’t believe this is possible. I’m assuming the “source” you’re refereeing to is the internal media player?

  • April 1, 2017 at 5:24 am Norm

    I have 4 of the new 65″ QMF series display series. The documentation seems to indicate that it can be used for a videowall, but there is DisplayPort Out on these monitors to create the loop-through. The manual illustrates how to daisy-chain control using RS-232 or RJ-45, but includes nothing on how to pass video from one monitor to the next.

    Any help you can provide would be great.

    • April 1, 2017 at 12:28 pm EZY

      Hi there,

      Thanks for your comment. Yes it’s interesting the QMF doesn’t have a Display Port Out but 2 Display Ports In. Have you tried connecting DP2 on Screen 1 to DP1 on Screen 2 and so on?

      • April 4, 2017 at 3:21 am Norm

        I haven’t done that yet, but will give it a shot and let you know…. Thanks, Norm

        • April 7, 2017 at 9:22 am EZY

          No problem at all.

          Let us know how you go.

    • April 1, 2017 at 5:29 am Norm

      Typo — there is NO DisplayOut (loop-through) ….

  • February 9, 2017 at 6:52 pm Daniel


    Im trying to get control of 50-60 screens.
    How can I manage to get them all to this control application if I’m using only RS232 ?

    • February 9, 2017 at 8:06 pm EZY

      Hi Daniel,

      No I don’t think this is possible as you would need a PC with many Serial Ports. Doesn’t the screen have Ethernet?

  • February 7, 2017 at 8:16 am Thom

    Hi there

    I’m trying to set up a video wall using dh55e although mdc looks like the answer no one talks about input. Forgive me if I’m being slow but I want to use an HDMI or doing source do connect the same signal via a d.a. to all four screens and the mdc then does the rest?

    • February 7, 2017 at 8:48 am EZY

      There are several ways to setup the video wall and below is a brief outline:

      1. Make sure you have the Input to the first screen as using HDMI.
      2. Then connect a display port cable from the Output Display port on the first screen to the Input on the Second Screen
      3. Then keep daisy chaining the Display port so that the output from one screens goes into the input until you have reached screen 4. For screen 4 all you will be using is the input.
      5. Connect all the screens to the network and make sure RJ45 is configured as the management interface
      6. Setup the video wall so each screen has it’s own unique ID. This can be done using the remote control or via MDC
      7. Setup the video wall so that it’s configured as 4×4

      Hopefully this helps.

    I want to control a single ME32C display from my PC (e.g. power ON/Off) with a custom application I am writing (C#/C++ application). I can do it with RS232C interface but i prefer the LAN interface.
    Can I do it from my own application (that can send Ethernet commands)? What is the communication protocol (TCP/UDP)? What is the port of the Display?


  • November 21, 2016 at 9:11 pm Dominik


    I wanted to download MDC software but it’s seems that via link you posted it’s no longer avaiable. Is it possible to get it ?


    • November 23, 2016 at 8:41 am EZY

      Hi Domink,

      The link still seems to be working. Could you please try again.

      • December 27, 2016 at 9:39 pm Marco

        It is not. We need it, thanks

        • December 27, 2016 at 9:43 pm EZY

          Hi you can see the link for the installer at the bottom of the post. Let me know if you have any other questions.

  • November 4, 2016 at 12:35 am Alex


    I have a samsung syncmaster 400dx-2 that was locked using an older version of the MDC software (i can only use it using a vga connection). Any ideea on how could i reset this action?

    Please help me if you have any ideeas!

    • November 8, 2016 at 11:52 am EZY

      Hi Alex,

      I’m assuming you don’t know the pin code to unlock the screen. The only way I’ve heard to unlock the screen if you don’t know the PIN, is to remove the internal battery (like the computer one) so that the memory is cleared.

      The default PIN the screens are set to is 0000. You may want to try different codes.

      • November 15, 2016 at 8:44 am Alex

        Thank you for your answe! I downloaded rhe software you previously uploded from samsung, but it requires a username and a password. Can you help me with this?

        • November 15, 2016 at 8:51 am EZY

          When downloading from Dropbox you don’t need a username and password. When you start MDC just leave the username and password blank.

          • November 23, 2016 at 2:29 am Alex


            If i leave the username and password blank, the only option i have is to close the software. I cannot access any option or menu.

          • November 23, 2016 at 8:42 am EZY

            Hi Alex,

            Have you tried admin as the username and no password.

            If that doesn’t work, try uninstalling and then reinstalling the software again.

        • November 15, 2016 at 8:51 am Alex

          By the way… i don’t have a screen anymore. It’s locked in “pc connect” via vga connection. This is actualy the issue. I can’t change it to hdmi or any other source.

  • September 21, 2016 at 6:27 am Maan

    I have one laptop and want to open 4 different browser on it and display each browser on different screen of video wall. Am using ud46-p . How can I do this using our end laptop connected to video wall and each screen showing different browsers.

    • September 21, 2016 at 10:50 am EZY

      Hi Maan,

      Yes you can do this. My suggestion is to use a tool called Launcher Dock which will allow you to start automatically a browser or application on each screen. You just need to set the location of where the browser should launch. The tool is free and good luck.

  • September 9, 2016 at 2:12 am Ed

    is it possible to use this software to create a 2×2 video wall using 4X DM32E samsung tvs? i can’t seem to figure out how to do it using this software. I have the screens connected to a switch via rj45 cables and then an rj45 cable connecting the switch to the computer. The tvs do come with magic info but i can’t seem to set up a video wall using the magic info application.

    Thanks Ed

    • September 9, 2016 at 1:02 pm EZY

      Hi Ed,

      You will need to firstly configure the screens themselves. Make sure you have configured the screens so that they are using RJ45 and that the magic info software can see each screen individually by giving each screen a unique ID.

      If you can’t use MagicInfo then try using MDC and see if you can connect to them via that software.

  • September 1, 2016 at 10:05 pm Jody Botting

    I’d like to connect MDC with 4 x UED46 monitors and am hoping to use it to change between a 2 x 2 video wall with the same input (DA’d HDMI probably), and showing a single input on the DVI input, unscaled.
    Does anyone know if you can assign the video wall to specific inputs or will I need to switch video wall off to then switch to a single input?

    • September 2, 2016 at 1:11 pm EZY

      Hi Jody,

      Great to see you using MDC. From what I understand, do you want to display the same content on all 4 screens via HDMI and then on each screen individual content via DVI?

      Have you tried the Samsung MagicInfo Videowall software?

  • August 22, 2016 at 4:33 am KID

    I need some help here… MDC which I downloaded (from the link you provided), looks a bit different than on the slides on this site.
    I’ve just connected my monitor via RS232 and MDC says that I have 1 connected device but all tabs are grey, so I can’t do anything but change user settings and logout.
    Do I have to have multiply monitors connected to start using this application? I just need it because it has option of virtual remote control which I don’t have to unlock Safety Lock on my monitor.
    Thank you all for help!

    • August 22, 2016 at 10:46 am EZY

      Hi there,

      Yes, the download link is a newer version and the interface is different.
      Which model of the screen do you have?

      A few things to check is to make sure on the actual monitor, you have setup an id for each screen and make sure RS232 is selected. Also read this article on how to scan for the device

      With regards to the Safety Lock, there is a button on the remote control to Lock/Unlock the screen, then you need to enter the pin. The pin by default is 0000.

      Hope this helps, if not then let me know and we can try to help further.

    Wanted to check if I can use the MDC software with the Samsung Smart Signage TV ?

    • January 28, 2016 at 1:45 pm EZY

      Unfortunately I don’t believe it works with a residential Samsung Smart Signage TV.

  • December 31, 2015 at 1:06 pm Bob the TV Guy

    Is the software available. I can’t find it anywhere. I have a 400fx display that I can’t access or use without the software. It says it’s locked.
    thank you,

        Hi, stupid question but how can i get my PC to see the Monitor? I have a Samsung 320TSN and I have downloaded MDC and the display driver but the MDC programme doesnt find the Monitor, if wont find the IP? is there something i need to do to obtain the IP on the display?


    • January 2, 2016 at 5:49 pm EZY

      Hi Bob, unfortunately it looks like samsung has removed the dropbox link.

      I will ask for it to be re-enabled.

          Looks like they have removed it. I’ll see if they can upload another one.

  • April 8, 2015 at 7:04 am Adam J.


    Thank you for this post, it is very helpful.

    Question: I have 4ea. Samsung DB40D monitors in a 2×2 configuration. Is it possible to connect all four monitors via Ethernet as opposed to connecting one via Ethernet and then daisy chaining the rest via Serial connections?

    Thanks for any help you can provide.

    • April 19, 2015 at 2:38 pm EZY

      Hi Adam,

      Yes, you can connect all for monitors via Ethernet. That is now our current setup.

      All you need to do is install a switch so that each screen is connected to the network. Then ensure that each screen obtains an IP address and then configure it so that the MDC software can see it.

  • March 11, 2015 at 7:39 am George

    Hello guys
    The input sources where I conect then directly to tvs or on PC ?

    • March 15, 2015 at 7:54 pm EZY

      Hi George,

      The input sources are the devices you want to connect to the TV. For example, if you want to connect your PC using HDMI to the TV then you would need to connect it to the HDMI input of the TV. Hope this helps.

      Hi there,

      Have you configured the screen to use RJ45 instead of Serial?

  • July 30, 2014 at 8:45 am Spanky

    Do you know if these can be used effectively for digital signage application like panels in different locations connected on LAN instead of daisy chained in close proximity? Samsung DB22D for example?

    • July 30, 2014 at 9:51 am EZY

      Hi Spanky,

      The Samsung commercial grade screens are designed to be used for digital signage via the WAN or LAN. The DB22D screeens have a RJ45 port so that they can be connected to the network for management purposes and also for MagicInfo Lite.

    I like your information, and I really want to start using this tool.
    Problem is, that I bought my 3 by 3 lh55uec videowall second hand, so no software for me.
    Believe me, it is nowhere to be found on the internet, neither in the support centre of Samsung.
    Please, pretty please, could you mail it to me?
    Thanks a lot!
