Fuzzy / un-sharp when used for 2560x1440 27GL850 in mirror-mode

[tsujp]

Great app, I've just spent an hour or so playing around with it and while I can get it to work with flickering (as this is a high refresh rate display) which is already known, window edges and other straight lines which are very sharp both without this running and on the in-built laptop display become fuzzy, sort of "out of focus" if you will. It's noticeable that the image being pushed to the screen is not the native image. This is great for text but bad for almost everything else.

Is there a known workaround here or will that always be a consequence given the behaviour of display mirroring? I couldn't get display streaming to work to test that out.

Hi @tsujp mirroring should not produce an issue like this. If you use 2560x1440 hidpi on a native 2560x1440 display, the only thing you might notice is that originally pixel-sharp lines might become somewhat blurred. This is the result of the 2x supersampling that occurs since 2560x1440 HiDPI is rendered at 5120x2880 and then downscaled to the display's native 2560x1440. The effect might be similar to antialiasing in PC games (if you are into that world). It is not that visible with text as that already has some smoothing applied by default. Some like this change, some don't - honestly I don't see much point in rendering the desktop at 1440p HiDPI on a 1440p display - the only benefit might come when you use accessibility zooming or create screenshots (both of these will be high-res this way).
