Hi Mark,

     Here is the QT's version:
qt.qpa.screen: EDID data for output "HDMI-0": identifier '', 
manufacturer 'Philips Consumer Electronics Company',model 'PHL 498P9-', 
serial 'AU02034002734', *physical size: 1190.00x340.00*
qt.qpa.screen: adding QXcbScreen(0x55780d9ab110, name="HDMI-0",
     geometry=5120x1440+0+0, availableGeometry=5120x1417+0+0,
     devicePixelRatio=1.0, logicalDpi=QPair(96.0,96.0),
*physicalSize=1.0x1.0mm,*
     screenNumber=0, virtualSize=5120x1440 (5120.0x1440.0mm),
orientation=Qt::LandscapeOrientation, depth=24, refreshRate=70.0,
     root=1e6, windowManagerName="Xfwm4") (Primary: true )

     Forgot to include the data after setting the screen size to 
3480x1080 to compare the results. In this size, the GUI starts fine in 
terms of font size:

qt.qpa.screen: EDID data for output "HDMI-0": identifier '', 
manufacturer 'Philips Consumer Electronics Company',model 'PHL 498P9-', 
serial 'AU02034002734', *physical size: 1190.00x340.00*
qt.qpa.screen: adding QXcbScreen(0x556e22d78310, name="HDMI-0",
     geometry=3840x1080+0+0, availableGeometry=3840x1057+0+0,
     devicePixelRatio=1.0, logicalDpi=QPair(96.0,95.9),
*physicalSize=1193.0x336.0mm*,
     screenNumber=0, virtualSize=3840x1080 (3840.0x1080.0mm),
     orientation=Qt::LandscapeOrientation, depth=24, refreshRate=75.0,
     root=1e6, windowManagerName="Xfwm4") (Primary: true )
