Jenkins가 오래된 버전이라, 시스템 전체에서 변경하는 방법만 존재하는 듯.
Since Jenkins is an old version, it seems like there is only a way to change it system-wide.
Manage Jenkins -> Configure System -> .Xvnc Command line: /usr/bin/vncserver :$DISPLAY_NUMBER -geometry 1920x1080
Job 수행 후 Console Output에서 vncserver 검색해서 지정한 해상도로 수행되는지 확인.
After executing the target job, search for 'vncserver' in the Console Output and check whether it is executed at the specified resolution.
