Ok, here are the things I've identified:
1) If I start the reader, the Irex logo is displayed plain wrong. The lighter grey that is used for the upper left part of x in Irex is simply not visible. The background that is supposed to be behind the big I is barely visible. In short, all colors are much lighter than they should be, in fact you can only see one shade of grey. If I shut down the device and start again, no change.
However, if I reset the device after it boots, it does some sort of calibration at the beginning of the boot, and the logo is displayed with correct colors this time. (Actually the same calibration like thing occurs on normal startup too, however it just does not end up right)
If I shut down after the reset, the logo is not displayed right. The only way to get the colors of the logo right, is to reset the device. Normal shutdown can not do this.
2) At any time, on a pdf or a writing pad (which is also pdf), if I write something down the colors are lighter than they should be. If I press the main button and display the menu, the colors are fixed immediately, and they stay that way, however new writing again appears with lighter colors. Another display of the menu refreshes the whole screen and all writing goes to dark color again.
I believe it is a software issue. I've been testing this behavior all day, in different light conditions, and the problem is consistent.
3) There is some ghosting on the screen, for example after the first boot, the large I in the logo can be seen on the device, show and hide the menu, and it is gone.
I'll post this to Irex forums too.
Kind regards
Seref
