4K laptop to 1080p monitor

[bernandops]

I just bought a laptop with 4K screen and GTX 970m. However, due to people saying if I game by rescaling the display to 1080p, it will get blurry. Therefore I am considering buying an external 1080p monitor for my game, and my 4K screen for other tasks.

However, will this configuration yield a perfect 1080p gaming ? will the graphics be displayed as if my monitor is 1080p panel ?

Thank you for your answer guys.

displaying 1080p games on that 4K screen should work just fine. remember 4K = 4x 1080p. it should scale perfectly 1 to 4 pixels .

^ yep....though i can speak from experience...things like AA don't work properly. I don't see a differance with AA on until i render at 1440P or greater on a 4K panel. at 1080p even with max AA it looks like it isn't on at all.

I understand about the multiplier and stuff, but somehow people said that it is not that straightforward. do you have a real experience regarding this ?

I do as i said. i run a UN55JU7500 curved screen 55" UHDTV...he is correct it scales without distortion but as i mentioned things like AA do not work properly. Basically even on, it looks off. your stuck with the jaggies until you render at at least 1440P (though has some very minor distortion since 720P x4 not 1080P x 4) but AA does help remove the jaggies to a degree. Preferable at 2160P if you wish to use AA to its full effect.

As far as a separate 1080P panel it should render 1080P natively just fine.

4k do tend to smooth out the edges of objects, although some panels are very good at minimizing that effect. They can display 1080p content almost as crisply as a native 1080p TV can. I would say a screen from a laptop would do this perfectly since your pixel density will be very high.

you can see many screenshots comparisons online. from people playing PS4s on 4K Tvs to powerful PCs running different resolutions and different AA settings.

that's what I am thinking. I think if you upscale from 1080p in a 15" 4K screen there should be minimum blur because of the density. but if you upscale it in a massive TV then the blur and blocks will appear so distinct.

I play PS4 on a 4K TV and for me it looks better than my 27" 1080p monitor. I wouldn't worry with a laptop
