HP Monitor 1600x900 thinks it's showing 1440x900

Hello Congo,

Thank you for the logs, this is helpful.
Your monitor does not use the VESA standard timing whereas the VESA standard timings are being sent.
The signal sent to the monitor is 1600*900 @ 118.25 MHz
The signal the monitor expects is 1600*900 @ 108.00 MHz

This is not really a resolution issue but a "detailed timing" one. The OSD doesn't measure but does a guess, and guesses wrong.

I've flagged this to engineering to see what we can do to use the monitor detailed timings instead of the standard VESA timings. However this is not a quick fix I can just give you now, unfortunately.

Kind regards,
Alban
