Full HD vs 4K Laptops Battery Drain Question

[Mr.Muffins]

I was wondering, will a 4K display set to a lower resolution compare to a Full HD laptop in battery consumption? Will it be better or worse?

 

I just wanted to know if switching the resolution on and off with a 4K display will benefit me in the long run.

Doesn't matter if the screen is set to 4k or 1080p it will consume the same amount of electricity since all the same pixels are still turned on, all you're doing is causing interpolation.

 

Now if you render a game at 1080p opposed to 4k targeting V-Sync to reduce the GPU usage % then you might save some electricity there but if the workload is the same like just internet browsing then there won't be a difference.

Thanks for the reply 

 

That's what I thought, lowering the resolution doesn't change the number of pixels which are always being utilized, correct?

 

So in the end, if I don't fully use the 4K display, then it's better to just save some cash and go for a Full HD one?

I believe so, personally I'd stay away from 4k in a laptop because the pixel density will be far too exaggerated to the point you're really not getting much advantage there, specially for mainstream usage.

 

even a 15'6 inch screen looks really crisp and pretty at 1920x1080p and pricing will be far more attractive.

Thanks for the lesson, appreciate the help.
