Here I've decoded your EDID using 'xxd' and then 'edid-decode':
EDID version: 1.3
Manufacturer: SAM Model 509 Serial Number 1
Made in week 48 of 2008
Digital display
Maximum image size: 16 cm x 9 cm
Gamma: 2.20
RGB color display
First detailed timing is preferred timing
Display x,y Chromaticity:
To be absolutely sure you would need to:
1. Convert the display's EDID into binary from hex:
00004c2d09050100
30120103801009780aee91a3544c9926
0f5054bdef80714f8100814081809500
950fb3000101023a801871382d40582c
How can I check if the hardware is really sending faulty data or if it
is just incorrectly parsed?

Sorry I lost track of this bug. The attachment in comment #7 shows:
HDMI-1 connected 1920x1080+1366+0 (0x8b) normal (normal left inverted
right x axis y axis) 160mm x 90mm
So the hardware is indeed reporting itself as ~7.2 inches. This is a
hardware fault (incorrect EDID data?) I have seen before

I generated the output and attached the section for the external
display. I guess the first line already shows the problem:

It includes "160mm x 90mm" which probably translates t
