Your BenQ BNQ76DB is very different from mine

[ohmantics]

Looks like my monitor was made later in 2007 and has a few significant differences in it's EDID. Most notably, mine comes up with interlaced descriptors and yours is not. Perhaps that's because I'm connected via the HDMI port. I came here because the BIOS on my Asus Z690 Formula motherboard is confused by this monitor and displays the BIOS in 1920x540, presumably because it isn't expecting an interlaced display.
