The eco mode is not usable, it's the manufacturer's way around a ban of 8k monitors. These monitors use at least twice what other monitors of the same size use, sometimes it's four times as much. And these measurements are probably in eco mode, so it could be worse.

Not sure why you mention this here? Just because we had horribly inefficient light bulbs our monitors can use twice as much?
I’m guilty of this as well. Folks of a certain age will always tend to measure energy consumption in “light bulbs.”
Sort of like how Americans always measure size in “football (gridiron) fields.”
The energy consumption of a traditional incandescent bulb, while obviously inexact, in nonetheless somewhat of a useful rough relative measurement. It is a power draw that is insignificant enough that we don’t mind running a few of them simultaneously when needed, yet significant enough that we recognize they ought to be turned off when not needed.
I always turn my monitors to the lowest possible brightness for long work sessions, so I assumed (perhaps mistakenly) that this eco mode would already be close to my settings out of the box, and if anything, too bright. Assuming 20c per kWh (California rates, mostly solar during the day) and one kWh per day (8h at 130kW average use), much higher than the allowed EU limit and the eco mode, the monetary cost comes down to about 4 USD per month. So definitely not negligible but also not a reason to avoid being able to tile 64 terminals if one wanted to do that.
[edit: the above estimate is almost certainly an upper bound on the energy I would ever use myself with such an item; I would be curious to measure it properly if/when I upgrade to one, and curious if the OP has a measure of their own usage. My best guess is that in practice I would average between 2 and 3 kWh every week (2 USD/month) rather than 5 kWh, because I tend to work in low light.]
