Another factor to take into account with resolution is battery life, specially for a portable device.
Got reminded of it while reading this, "There is a downside to going with the 4K version: Lenovo says you should get around 15.5 hours of battery life with a 1080p version of the laptop. That number drops to 10.5 hours for the 4K model."

Well. Yes. Increasing resolution does come with the caveat of higher power consumption, provided everything else is equal.
There have been cases in the smartphone world where a manufacturer like Samsung has shifted over to a 1440P display... Which actually used less energy than the 1080P display on the prior model, mostly because the panel technology is far more energy efficient.
Another example is when displays made the shift from Cold Cathode Fluorescent Lamp (CCFL) to Light Emitting Diode (LED) as the backlight, big gains in form factor, cost, energy efficiency and brightness was achieved, regardless of the resolution.

That could happen, although due to the technology used and not resolution.
