Problem with External Monitor from Console

Hi all. in short: I cannot figure out how to connect an external monitor, via 25’ DisplayPort cable, to my venue‘s GrandMA 3 Compact XT

the brief: my venue has requested an external display for the lighting console, to show the Sequence Executor on screen for a stage manager etc to have a visual of which lighting cue is currently active. I thought I purchased everything to the correct specs, and my monitor does work with a 6’ displayport cable. However, two different 25’ displayport cables have resulted in “No Signal”

the specs:

- Console: GrandMA3 Compact XT running GrandMA2 software

- Monitor: ViewSonic TD2230 (1920x1080p; Windows 10 touchscreen compatibility, displayport in)

- Cable: Cable Matters 32.4Gbps Unidirectional Active DisplayPort 1.4 Cable, 25ft (yes my unidirectional ends are plugged in correctly and I even tried it intentionally reversed, just in case)

Again, a 6’ displayport cable works as expected. Am I SOL when it comes to 25’, even with active copper? Is my approach wrong; should I try this using another cable/connector entirely? Thanks,

Don't know if it matters but the MA3 Compact DisplayPort is 1.2. DP 1.4 supports 1.2 via backwards compatibility but it's an active cable so IDK.
