Hello,

I just installed Krita on my new computer. My resolution should be 1920x1080, but Krita seems to do something else. I can't figure out a way to get this right. I uninstalled and reinstalled but this didn't change anything. I remember having a popup on the first start-up where I chose to put my resolution. i must have done something because it didn't re-appeared on the second installation.

Thanks for the help.

Check the display scaling settings of Windows. That probably should be 100%; if the problem persists, disable the HiDPI option in Krita's settings. I don't know what that's called in French, so you'll have look for that in the settings dialog.

Perfect ! The display scale caused all that. Thank you so much
