Dual monitor setup questions.
Milsancho:
So before buying anything, I'm trying the dual analogue output with an HD 4550 first (so no Edid emulation). I have installed 15khz modes only though, and I'm wondering, if I install 31khz modes (despite having already 15khz versions of some of them), the process is just setting extended desktop for the new display (a 31khz PC CRT). This monitor is not the one used in the installation process and it doesn't seem to be acknowledged by Windows as such.
Will Windows automatically set a compatible video mode for this new monitor "1" during the desktop extension process? Will I be able to use Arcade OSD to set modes in this extended desktop configuration?
Thks.

ED. Nevermind; I misread your post.
Milsancho:
In the case my previous post is a bit convoluted, I'm just having a monitor detection issue. Windows (7) isn't acknowledging properly I have a VGA monitor connected with the HD 4550 and Emudriver.
The monitor works fine as the BIOS is displayed when booting the system, but as mentioned it's not the one used when I did the emudriver installation. I don't think that should matter anyway as both are VGA PC monitors.
When I try to make a desktop switch (in order to use what Windows calls display "1" instead of "2") through Windows' display management app, the VGA monitor is shown as "generic no PnP monitor" (which should not be a problem) and I can't pick a resolution mode for being greyed out (I can for the 15khz monitor, though).
Any idea as of how to force monitor detection in this case? I guess I could try reverting the process explained here: http://geedorah.com/eiusdemmodi/forum/viewtopic.php?pid=1019#p1019
but really, I'm afraid of ending up with no picture whatsoever.

Did You enabled EDID emulation on both analog outputs ?
Milsancho:
I think I didn't. I'm using an HD 4550 so that's not really possible?
