Blade QHD, can it be run at 1080 to conserve battery life?

    so since the 3200x1800 is the same aspect ratio as 1080, then this would mean running it 1080 wouldn't look weird, so surely running at a lower res would conserve some of the battery life as ive heard the QHD screen reduces the battery life more than the FHD

    It'll conserve some, but not by as much as you'd think, the main difference is that your cpu won't work quite as hard to draw frames, which will save a small amount of power, but ultimately the main power draw is the screen itself, which is still going to draw the same amount of power no matter what resolution you run in, it's still shining the same amount of light, still having to display on all those pixels.

    I tried that once, and text and icons dont look right, slightly blurred, I needed the QHD for photo/video work, so if you're planing to work on the machine Leave it at native, otherwise just shoot for the FHD.

    I would say its more that the battery has to power way more pixels then the 1080p version. even if you down the res to 1080, it still has to power way more pixels then the QHD version. but it would save a little gpu power probably since it is lower res. but not as much as having a FHD screen
  5. It would look weird because, and I can't think of a better way to explain this, but 3200x1800, when divided by 1920x1080 won't give an integer, you won't have an exact number of pixels acting as a single pixel, causing inaccuracies. Battery life might be conserved a little but not much at all as you're still having to drive the same number of pixels on the display itself, and it's not that much less stressful at 1080p on the intel graphics for day to day tasks.

    Sorry, can't answer on the battery power.... BUT....

    You should drop down to 1600 x 900. NOT 1080p. Because at 1600x900 every GPU pixel maps perfectly to a square of 4 pixels on the screen, so you still get a perfectly crisp image. And on a 14" screen, 1080p is not really much higher than 900p anyway.

    I know a lot of people like to buy the Blade 14 with the 1080p screen, but I found that buying the QHD+ screen gives me a great image on the windows desktop, and a touch screen, while allowing me to still run a really sharp 900p when needed for best speed.

    hmm ok cheers guys, yea im using it for filmic stuff so the colour accuracy was tempting, as was the glossy screen, but the poor battery life is deterring me. not ot mention i have no interest in playing games at above 1080, was hoping maybe the touch and other stuff could be disabled to conserve power. Although 900p wouldnt be too bad, but if im not saving much power then theres probably no reason to drop it down other than for games

    I guess I should mention - if you want to maximize battery life, you should configure the Intel Graphics driver so that it goes into "maximum power savings" mode when you are running off of battery. This should probably accomplish what you were hoping to do, but does not require reducing the screen resolution.
