Hi,
I’ve two monitors, one monitor with HDMI and another monitor with VGA
I’ve connected the first monitor with DP cable to HDMI
but the second monitor doesn’t work, i’ve used a HDMI to VGA adapter and connected it to the second monitor.
If you really want / need the VGA monitor, and it has a DVI port you could try an HDMI to DVI converter. Perhaps using an HDMI to DVI and then a DVI to VGA adapter could also work, but I doubt it. The reason DVI could work better is because the video part of the HDMI signal is identical to DVI (which I think means that adapters are “dumb” and don’t have any analog to digital logic).
