Interested to know how much less for lower resolutions. I'm not sure I've ever cared for high resolutions - and I'd always pick more battery life given the choice.
on my laptop (specs wise - consider steam deck non oled, but worse graphics performance, 1080p screen (IPS)) - 5.3-6 Wh for 2x speed playback. for full hd playback 6-7 Wh. Idle power is much higher though 4.5 Wh, on my old laptop, video power consumption consumed similar power, but idle power was close to 2.5-3 Wh (in terms of specs, it had halve the number of cores, and a tn panel)
That is an interesting take. Can I save a lot of battery by choosing 1080 instead of 2/4k for laptops in general? You don't really need 2k for prose text or programming anyway.
Edit: no https://superuser.com/questions/974045/does-changing-the-screen-resolution-affect-power-consumption
Yes. What your link states is that running a 4k monitor at 1080p wonβt save you power (it will, but via gpu, not monitor draw).
A 1080p monitor will require substantially less power than a 4k monitor, all other factors held equal.
