Hello. I know this isn’t completely related to Linux, but I was still curious about it.
I’ve been looking at Linux laptops and one that caught my eye from Tuxedo had 13 hours of battery life on idle, or 9 hours of browsing the web. The thing is, that device had a 3k display.
My question is, as someone used to 1080p and someone that always tries to maximise the battery life out of a laptop, would downscaling the display be helpful? And if so, is it even worth it, or are the benefits too small to notice?
For an external display I’d bet the case is the hardware driver for the panel.
At least my 17" Powerbook G4 with a massive 2560x1440 display does it in the software display driver. I’m sure some laptop panels do it in hardware as well, but seems there’s some very janky shit going on at least with laptops that have both integrated and discrete GPUs.
