I have an HP ultrabook which does not have a VGA-out port. I would like to connect it to a VGA only projector Will a hdmi to dvi converter like and then a DVI to VGA converter like setup work ?

Or do I need something like ?

Standard HDMI<->DVI-D + DVI-A<->VGA won't work. But you should check whether your device is compatible with this kind of adapter, your HDMI port may not only be a standard HDMI port. – zakinster May 17 '13 at 14:56

HDMI can easily be converted to digital DVI.

Analog DVI can easily be converted to analog VGA.

The step in the middle where you want to convert the digital DVI to analog DVI is not trivial and requires an active and relative expensive* adapter.

It might actually be cheaper to buy an USB graphical card with a VGA out and use that as a second display.

*Expensive as in the order of: £50 / US $76 / 4100Rp

HDMI is digital-only. VGA is analog-only. You will need an active converter.

I thought only VGA to HDMI meeded a converter, but HDMI to VGA doesn't? – tarashish May 17 '13 at 14:36
@tarashish Both require an active converter. It's possible that one might require an external power source, and the other might not, however. – Darth Android May 17 '13 at 14:36
It seems I'm doomed then. – tarashish May 17 '13 at 14:37
Actually some non-standard HDMI sockets contain some pins for analog output, especially on mobile devices (example for some Asus tablets). But this is completely manufacturer/device specific. – zakinster May 17 '13 at 14:46
