10 Monitor Setup


I’m running Windows 7 on a Dell Optiplex Core I7 computer. I’m trying to run 10 of the pluggable 4K HDMI adapters to 10 50’’ UHD monitors for a data display application. I have 3 monitors but when I plug in the 4th monitor I can not increase the resolution to 4K. It will just revert to the lower resolution when I try to apply the change. Is there a limitation to how many monitors can display in 4k on a single computer?


Hi Brent,

Thanks for posting. It does indeed sound like a resource limitation might be coming into play here. Most modern USB 3.0 systems can support between 2 and 6 USB graphics adapters. (And we’re of course happy to help with a return for a refund on any or all of the adapters if needed.)

To get a better understanding of where the limitation is occurring, can you do a quick test to see if you’re able to add more displays if you set the current 4K displays down to 1080P?

Also, could you please collect a set of system logs with our tool at the page below? It will save a .ZIP file to your Desktop which can then be emailed to support@plugable.com (Ticket 191460)? We’ll have a look and see if there are any updates which may help.
