I have a MacBook Pro 2017 (two USB-C ports only), running Ventura. I have a USB-C to HDMI female adapter and a HDMI (male) to DP (male) cable to connect everything to a Dell P2415Q. But there arrives no picture on the monitor; it only says 'there is no signal coming from your computer'. The problem persists with different such cables and adapters. Only connecting the adapter to the monitor with a HDMI-HDMI-cable that I borrowed worked. Is there any chance to connect the computer to the monitor with the USB-HDMI adapter and the HDMI-DP cable only?

This will not work.
What you’re doing is is taking a DisplayPort signal and converting to HDMI which removes the clock signal, then converting it back to DisplayPort which needs one.
What you need is a quality USB-C to DisplayPort cable. The linked answer is in relation to a similar question of converting TB3 to TB2 to DisplayPort. Even though each signal was technically compatible, the multiple conversions proved unreliable. Your setup is much more complex; converting actual signaling configurations from DP to to HDMI back to DP will likely never work.
