Hazro H27WC: DP to DVI not working

[Nonameneeded]

I've found this old monitor on Gumtree for 50£. The pc I have (HP Z400 has an Nvidia Quadro nvs 295).
The Quadro has Displayport connections, the only way to connect them to the monitor it's a DP to DVI adapter
I've tried two different adaptors but screen remains black and blue light keeps blinking.

Any suggestions? Thanks

You need a active DP to dual DVI cable.

Would you pls suggest me which one should I buy? I've bought two on Amazon and none of them works.
