It's a bit frustrating to still collect logs when nobody tried to look at the issue yet. The previous set of logs was pretty detailed and I also found differences in the register values. Unfortunately, the same debug parameters don't work with the latest kernel and I need new parameters in order to provide you with useful data. Maybe you had no time to read all the comments. We found, that it has nothing to do with the resolution. The problem lies in the digital part of the DVI-I-2 output. Whilst the analog pins of the DVI-I-2 output work like expected, the digital pins are off (black screen and blinking LED on the second monitor). That means I can use the second display only when it is connected with an analog cable via DVI->DSUB adapter inserted in the DVI-I-2 port. Anyway, I'll attach my current dmesg output with no additional debug information shortly (collected while having the second display connected via the DVI->DSUB adapter). Please, let me know about the next steps. It would be nice if someone could finally find some time to look at the register differences (attached to this report). Thanks in advance.
