Bug ID: 94817
Summary: Nearest neighbor scaling?
Product: xorg
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: enhancement
Priority: medium
Component: Driver/nouveau
Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
Reporter: nw9165-3201-/E1597aS9LQAvxtiuMwx3w@public.gmane.org

Hello,
would it be possible that you add a nearest-neighbor scaling mode to the
driver, so that one could display 1920x1080 natively on a 3840x2160 monitor or
1280x720 natively on a 2560x1440 monitor and so on (one pixel becomes four
pixels)?
There is some information on this topic over there:
https://forums.geforce.com/default/topic/844905/geforce-drivers/integer-scaling-mode/
Regards

This should be possible with xrandr, or directly via the kms api. It defaults to no scaling for external screens, as those usually have better scalers built in.

It has resulted in a patch for xrandr that allows to use nearest neighbor scaling now, see: https://bugs.freedesktop.org/show_bug.cgi?id=94816 https://bugs.freedesktop.org/show_bug.cgi?id=94820 https://bugs.freedesktop.org/show_bug.cgi?id=94819 Anyway, as already being discussed in those three threads, it would be interesting to know if the dedicated hardware scaler inside the GPU could also be used for this instead of using xrandr. Can anyone comment on this? Regards -- You are receiving this mail because: You are the assignee for the bug.

Run 'xrandr --props' to find the exact property. IOW the feature already exists. -- You are receiving this mail because: You are the assignee for the bug.
