I’ve had a few people tell me this over the years and just wondering if anyone knows how true it is. I guess the sentiment is that 1080p on any gaming pc device including laptops is much easier to run, and is way less harder on any gaming pc or laptop. Therefore the laptop theoretically has a much higher chance to last longer than a 1440p or 4K gaming laptop. Any truth to this?
True to some extent. It does take more power to render 1440p image vs 1080p.However, this it highly depends on the programs/games that you’re going to run.
For basic stuff, like browsing, emails, text editing or spreadsheets, difference is negligible. Maybe 1-2%.
For gaming or something gpu-heavy, it will matter if you tun it a native resolution (which it usually does by default). With a typical example of those being games, in 99% of them you can manually set a render resolution at 1080p manually, so it will take same amount of energy.
Overall it matters, mostly for games and even there you can turn it down to 1080 to enjoy same battery life or better fps. So having greater resolution doesn’t hurt at least and improves image details usually.
