Hello !
In this topic I can read the VGA2HD2 is compatible with 720x400@70.

VGA to HDMI supporting 640x480@60 and 720x400 @70

Hi All, I am really desperate, trying to source a VGA Input to HDMI Output Adapter that supports both 640x480@60 and 720x400 @70. I dont seem to be able to find anyone that may stock this item or find anyone that could cutom make this. I would appreciate any help or recommendations. Thank you!!

But I think buy VGA2HDU, can anyone confirm this adapter working well with this resolution?
To be more precise, is to have the POST boot on servers.
