Hi there, I'm currently using a dell xps 15 9560. Sometimes I would use 1080p to some applications not scaling properly. Like autoCAD 2016 student ( my school don't use 2017). However the change to a non native resolution results in blur which Is way worst than normal 1080p monitors. The blur doesn't happen when playing on games in 1080p on the gtx1050. Even when playing games on 1080 on the integrated graphics, there are no significant blur. Only when going round windows or browsing will result in 1080 blur. 1080 should show perfectly on a 4k native screen as 4k have 4 times more pixels than 1080 which 1 pixel of a 1080p should become 4 pixels in 4k.
