4.5m DisplayPort to HDMI cable does not work

Question

I connected my Desktop PC to a monitor via a 4.5m long DisplayPort to HDMI cable, but the monitor does not receive any input signals.

What I have tried so far:

I changed the cable but got same result
I updated the drivers to the last version of my "Intel® HD Graphics 630" card
I connected the same monitor with the same cable to another PC and I got the signal
I connected the same monitor and my desktop PC with a shorter DisplayPort to HDMI cable (same connection as the long cable) and I got the signal

This is a link of the DisplayPort to HDMI cable I bought:

Do you have any suggestion for my problem? Could be possible that the output signal of my PC port has not enough strenght?

This is a "DisplayPort to HDMI" cable... not a plain "DisplayPort to DisplayPort" cable... Which end is connected to which? Is the HDMI end at the PC or Monitor? — Attie, Commented Oct 9, 2018 at 13:02
Is the "shorter DISPLAYPORT cable" also actually "DisplayPort to HDMI"? Is it oriented the same way? (i.e: HDMI at the Monitor in both cases) — Attie, Commented Oct 9, 2018 at 13:05
Note: A DisplayPort HDTV cable can only be used in one direction: the DisplayPort connector can only be used on the data source side (e. g. graphics card). This is straight from the website, and underlines Atties comment. — Nordlys Jeger, Commented Oct 9, 2018 at 13:09
Both cables (short and long) are "DisplayPort to HDMI" and I used same orientation. The DisplayPort is connected to the PC, the HDMI to the monitor. I'm trying to use 1980x1080 resolution. — Nicola Trenti, Commented Oct 9, 2018 at 13:14

I solved my problem by changing the graphic card:

"NVIDIA Quadro 2000" works properly

Maybe also using an active DisplayPort to HDMI converter could be a possible solution, but I cannot try this solution at the moment.
