    Disable the automatic blur on apps which don't render HD

    I just got a laptop with an HD screen for the first time. Many apps don't render in HD yet, so they don't provide enough information to create a high-res image on the screen. The way that W10 deals with this problem is by filling in the gaps between pixel information by blending the nearest pixels together. However, I strongly dislike this effect as it makes apps look "fuzzy" and makes me wonder if I need to get my eyes checked.

    To give an example, here is an image with no blur effect (taken with Nesbox emulator):

    And here is an image WITH blur (best viewed full-size to see the difference):
    Click image for larger version. 

Name:	Blur.png

    The Nesbox emulator I got these images from has a very easy "on/off" switch for this effect. I'm curious to know if there is a way to disable the blur effect in Windows 10 as a whole. Does anyone know how to do this?

    It is not Windows that is doing that. It is your graphics card. It is using a scalier to scale those images to fill your screen. Since I don't know what laptop you have, I don't know what hardware you have. Thus I cannot really tell you what to do. But you should look though the settings of your graphics card.

    Edit. NVM I looked at this NesBox, the blur thing as far as I can tell is purely something NesBox itself does. None of the other applications exhibit any type of blurring.

    @logicearth - Thanks for looking around.

    Quick clarification, the Nesbox thing was just an example so that I could show the difference between blurred and non-blurred imagery. Certain apps (like Spotify) are completely blurred, similar to the 2nd image, so that even the text on the page and the top toolbar are fuzzy. Nesbox itself renders in HD -- its toolbar and text are HD -- and only the game window it contains was blurry.

    Apologies if I posted this thread in the wrong place. I'll look into graphics card options to see if I can find something.

    Windows 10 (duh)

    Seems like you need to use this option: right-click app - Compatibility - Disable display scaling on high DPI settings.

    For apps that actually change your resolution, you need an option in the GPU driver: for example Nvidia has under Display -
    Adjust desktop size and position: Scaling=No scaling, Perform on=Display, Override games and programs

    Thanks! This works, but has the unfortunate side-effect that no scaling is done at all and text and images are very small. Still, it will work great for some apps.
