Connect XPS 15 9550 with 4K UHD screen to 1920x1080 external monitor
I have a display setting of 1920 x 1080 with 125% DPI scaling on my XPS 15 9550 with 4K UHD screen.
When I connect it to my external monitor with the same maximum resolution of 1920 x 1080 using the "second screen only" option under "Project" of Windows 10, everything seems to look smaller than typical 1920 x 1080 resolution. When I troubleshooted, the only option I could manage was to use the "duplicate" option instead of "second screen only" option. If anyone knows how to do it, please share with me. Thanks!
