The first of these resolutions indicates hexa “00001900 00000e10” is therefore a resolution scaling of … 6400 x 3600 (probably 3200×1800 HiDPI).
Continues and is 5760×3240 (2880×1620 HiDPI) 4096×2304 (2048×1152 HiDPI), etc..
(There are other resolutions, just make the conversion from hex)
With this alone, it is not possible to guess the native resolution of the machine. This is a resolution that does not appear in the file, since it is native and does not have to be “scaled”.
Knowing that there is a gap between the values of 5760 and 4096, one can imagine something between these two (probably 5120×2880, 2560×1440 or in HiDPI), but this is speculation. (traduzir)
