Hello,
about old pc monitors I've got this Acer AL1512 15" LCD XGA model that it's not the first one I've seen in linux having problems once the o.s./vga try to read the EDID from the VGA port and results as invalid, both with nvidia or radeon cards. Even if sometimes it still works with default resolutions and frequencies, I'd prefer to use its EDID internally so all values would be correct. I've seen that with an HDMI to VGA active adapter having probably its own converter IC, it works and read a usable EDID but not when connected to VGA directly to the monitor.
I've used the read_edid app on linux and even with the classic option I still extract an invalid EDID bin file. Without forcing a manual xorg.conf file with the values, are there any other possible app or command to use with the VGA only connection instead of using the HDMI converter to save it, cause I suspect once I'll use it I'll have problems later with HDMI audio vs the internal analog Realtek priority sound outputs list as already happened before.
Thanks
