PXIe -8821 and old dell monitor

[Clint1000]

I have a PXIe 8821 connected to an old Dell monitor.  The 8821 is using the DP port to the 25 pin d sub connector on the back of the monitor.  I'm using a DP to 25 d sub connector to go from the controller to the monitor.  When I hook up the connection the monitor goes dark.  Can you use the old monitor w the dp port?  Prior to this I was using a PXIe 8101 w the dell monitor and it worked fine.( D sub 25 to DVI)

Thanks

Hi Clint1000,

This KB looks similar to what you're talking about: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000001DcDhSAK&l=en-US .

It says that the only officially tested and supported adapters are those that NI sells. You may get other adapters to work, but their performance is not guaranteed.
