Hello,

I am looking for the best configuration to supply 16 small projectors with WVGA or 720 HD signals in Unreal Ndisplay. What configuration(s) do you suggest? thnks.

Hello @Jan!

Thank you for posting on our StarTech.com Community forum!

I would like to clarify more specifically what it is you are looking to do if possible.

  1. Are you looking for a solution to add additional video outputs to a PC to be able to attach these 16 projectors?
  2. Can you confirm what the video connection type would be used on the projectors as well as the make and model of these projectors?
  3. Are you looking to provide individual extended displays to each projector, or have them all mirror the same image?
  4. Can you provide any details about the source PC that you would be using to provide the video signal to these projectors? (Make and model, available video outputs, how many GPU’s are installed and their makes and models, OS version, etc.)
  5. How far away would the projectors be from the source PC?

With some of these additional details I should be more able to provide some suggestions. Additionally, I would also like to mention that you can reach out to us using the Live Chat feature on our website so you can discuss this live in more detail with one of our Technical Advisors which may be beneficial.

We look forward to hearing from you!

Hello,

thnx for the fast reply.

I want to address 16 and more display’s in Unreal Ndisplay. https://dev.epicgames.com/documentation/en-us/unreal-engine/ndisplay-overview-for-unreal-engine

Every nDisplay setup has a single primary computer, and any number of additional computers, called secondary nodes.

For this specific application, I want to address Microvision Showwx(+) laserprojectors. Microvision SHOWWX Laser Pico Projector Specs (projectorcentral.com)

Using a female yellow RCA as input connector, for Resolution
848x480 Aspect Ratio 16:9 (WVGA) (25 or 30 FPS ?)

As primairy node I am using for the moment a MSI Creator_17_B11UH(20240908)

As secondary node I use a MSI i7 with NVIDIA RTX470

about question 5 … depends on the configuration. No importance for the moment, as separate nodes can be created if needed.

Please let me know if you need additional info.

ps
I have StarTech 2 X MSTMDP123DP

Hi @Jan and thank you for this additional information.

Would you be able to expand in more detail as to the physical configuration of this? Are you connecting one physical projector to one physical computer and thereby using 16 computers for the 16 projectors? Or are you looking to be able to connect multiple projectors to the same physical computer?

Are you simply looking for a solution to convert a DisplayPort (or Mini DisplayPort) source connection to a Composite connection?

Or are you looking for a solution to drive more outputs from the one computer to be able to connect to multiple projectors?

I will also again mention our Live Chat feature on our website in case you wish to have a more in depth conversation with one of our Technical Advisors which may result in a quicker solution for you. Either way, we look forward to hearing back from you once again!
