So according to Energystar.gov, the annual energy consumption is 65.97 kWh/year. This calculation is based on the monitor being 35% in On mode and 65% in Sleep mode over a full year. https://www.energystar.gov/productfinder/product/certified-displays/details/2361630# Nevertheless, the above value of 40 kWh/year (from the series of pictures) may still be correct under certain circumstances, as our Federal Office of Energy calculates/calculated as follows for the above original label: 4h/day operation over 365 days. Now the dilemma: There was/will be a revision from 1 March 2021 for the energy efficiency class table. It will now be given per kWh/1000h instead of over kWh/year. This can lead to a device with A+++ (on the old list) dropping down to C (on the new list) - 5 steps down. For this monitor, class A (old list) corresponds approximately to class F (new list) - 5 steps down. https://www.bfe.admin.ch/bfe/de/home/effizienz/energieetiketten-und-effizienzanforderungen/elektronische-geraete/die-energieetikette-fuer-fernsehgeraete.exturl.html/aHR0cHM6Ly9wdWJkYi5iZmUuYWRtaW4uY2gvZGUvcHVibGljYX/Rpb24vZG93bmxvYWQvNjMwNg==.html This device was released on 28 October 2020 via EU DECLARATION OF CONFORMITY. Therefore, the energy efficiency class above (and everywhere else) is still class A - except for the new labels that come with the product. These are already up-to-date and are therefore classified as class F. https://downloads.dell.com/rdoc/dell%20monitor%20p2721q%20p2721qf%20p2721qf%20european%20union%20-%20declaration%20of%20conformity%20en-us.pdf

So what is really the energy efficiency class? A or F?

Hi! Can I attach the screen to a Mac Book via USB-C?

If I buy two displays of this model, can I chain them in USB-C to my MacBook Pro (M1 Pro) so that I only have one USB-C port connected to my Mac? Thanks for your help!

Is this Dell P2721Q adjustable in height? The description says height adjustable. But you can't see anything in the pictures. If it is adjustable, how many centimetres?

Hello Together I would like to use two of these monitors. Is there a way to do this without a docking station? The two devices for this would be a Macbook Pro 2021 and an HP Elitebook. Best regards

Hello Together Is there no indication at all here when this monitor will be available again? Since you can't see how long it has been out of stock, it's difficult to interpret...

On many forums I can read that this screen - connected through the USB-C connector on latest Macbook Pro M1 or air M1 - will : - have flickering issues after a while - may have to be rebooted after coming back from standby - the USB peripherals attached to the screen won't work if only USB-C is used Has anyone experienced these issues ? if yes, needless to say this monitor is useless on a Mac, unless you want to connect 2 cables (1 usb-c to usb-c, 1 usb-c to DPort for video).

Hello, is this monitor ok with MacBook Air? Thanks

Does anyone also have an inhomogeneous gradient on the left and right edges with a white background? For me, it is very annoying on the left, as the whole left edge of the screen seems slightly darker than on the right (about 0.5 cm), even though I am sitting in the middle and staring directly at the screen. I have the feeling that the panel is not turned on equally far to the front of the screen everywhere and that is why this phenomenon or something similar is occurring. I would appreciate a short feedback. Thank you.
