Monitor with HDMI-DP Connector with DELL D6000

[Sarastro]

Hello!

3 Monitor System with M2 Mac mini + Dell D6000 + 3 HDMI Monitors + HDMI-DP Converter. Dell D6000 has only 1 HDMI & 2 DP Ports and I bought ;

BENFEI 4K DisplayPort auf HDMI, Unidirectional DisplayPort DP Computer zu HDMI Monitor

This works more than 10 months without problem and today I have tested this configuration with my new surface pro once and the monitor connected through the converter has not been detected on Mac and on Displaylink manager as "No monitor" but on its screen I can see 640 x 480 extended screen from main monitor. I thought it could be the monitor compatibility but with other monitors + converter gives the same issue.

DisplayLink manager is the newest version. I have reinstalled it also. Somebody has similar experience?
