My friend said some of those display devices may have their own fine controls for scaling (on-screen menu?). But I only have this monitor (1440x900 it says IPS LED LG on front and "Manufacturer: GSM Model: 5b01 Serial#: 5886" in X.log) as my viewing device (I have older CRT monitors, Samsung SyncMaster 550b, but for now I prefer not to unplug vga cable too much - it sometimes loose red and blue signals, so I prefer not to strain it more) > > > Terje J.
