Found it.

It has a download for the USB-C ethernet drivers. It's near the bottom (at "Software & Drivers") and downloads as a 34 MB zip file. I tried downloading it on my MBP and it automatically unzips and with a folder that (at least today) is called "LAN Drivers_20220127" with separate zipped drivers for Windows 7, Windows 8, Windows 10, Windows 11, and MacOS. Not sure why, but there's no way to download just the MacOS version - it comes as a package with all of the drivers. The MacOS driver is called Mac OS_v1.0.21_20201019.zip and unzips as an Apple Disk Image file called RTUNICv1.0.21.dmg.

is any Ethernet interface shown in

System preferences > Network ??

if not click the Add [+] button below the list of interfaces, and select your interface.

When it shows up, be sure to make it TOPMOST by clicking the Gear icon and choosing 'Set service order', then dragging Ethernet to the top of the list of interfaces.

Had the 2019 MBP Pro connected to the Philips monitor, and everything worked.

Just switched to MBP M1 Max, and the computer do not receive any net connection through the USB-C cable, like the older model did.

Any idea if there have been any change of things making this setup not working the same way anymore?

Ethernet problem...?

are you asking about the monitor or your Ethernet

Looked it up, and this monitor has an ethernet port and a USB-C port, along with HDMI and DisplayPort inputs. My guess (we'll of course have to wait for confirmation) is that the OP used a USB-C to USB-C cable (at least USB 3.1) to connect video, and it could additionally handle networking from the ethernet port along the same cable.

You do not sat what exact cable/adapter this is ...(?)

Connect your Mac to the internet using Ethernet - Apple Support

Connect a display to your Mac - Apple Support

If Phillips used the same common chip that every other Mac Ethernet add-on uses, a driver is built into macOS, and is available by following the little procedure I suggested above. Downloading and installing a Driver should only needed if nothing comes up in

system preferences >Network

I hope SteinarBraa will let us know what they discover about this.
