Questions about Philips 328P6VUBREB/00

Good day. The energy efficiency class is stated as B on the digitec homepage under specifications. After I bought the product, I noticed that the monitor has an energy efficiency class sticker of C. What applies now? What applies now?

Hello! I have a delay in the display compared to the Macbook. The screen is connected with USB-C. I did not have this problem with the previous model. Is there an update for this screen? Greetings

Can this monitor also be operated with a remote control?

What cable do I need to connect this screen to the Mac min M1?

Can I connect this screen to the Mac min M1 without any problems? Which screen would be an even better alternative? Thank you for your answer.

Allegedly, the performance of the USB-C is throttled to the speed of USB-A by default. The USB-C speed can, also allegedly, be switched to the USB-C throughput in a cumbersome menu, but only with the restriction that the screen refresh rate is then throttled from 60Hz to half 30 Hz. Is this really the case? Greetings Daniel
