Have you ever wondered whether it was possible to change the contrast ratio of your Sony Reader screen? Well, now it seems you can, though the procedure is not for the faint of heart. Igorsk
pointed us to this (very interesting)
website explaining how you can adjust the screen ratio by changing the position of a specific resistor (yes, in other words, you'd have to disassemble the hardware). Whether the adjustment is for the better or worse, I don't know. Make sure to compare the screenshots.
