these are my monitor specs http://www8.hp.com/h20195/v2/getpdf.aspx/c04142050.pdf?ver=15 i have partially resolved in this way: hdmi_safe=0 hdmi_force_hotplug=1 hdmi_ignore_edid=0xa5000080 config_hdmi_boost=4 hdmi_group=2 hdmi_mode=35 disable_overscan=0 monitor signal is "stable", but i cant set hdmi_mode Greater than 35 otherwise monitor signal go up and down.. could it depends by my hdmi2vga converter?
