i think the issue is that the VGA is analogue and the HDMI is digital.

You should have a DVI port on the card.
Do you have a DVI cable?
Do you have a DVI port on your VGA monitor?
If you dont have a DVI port on the monitor, you can still use a DVI-VGA converter. This will be DVI going out, but will still convert to analogue VGA for you VGA port Monitor.

The card GTS 250 has issues with this on using both Analogue and Digital outputs at the same time.

would help if you told us the make and model number of the laptop.
It could be a limitation of the laptop.

I think this is a limitation of his graphics card. I posted in his other thread concerning the same matter : http://www.sevenforums.com/drivers/8...nt-please.html

Ah I am sorry. My laptop has a VGA and HDMI too, but I dont use both at once. it has a GTX 260M.... I thought you had a laptop graphics card. I will test when I can for my lappy. What kind of graphics do you have?

The short and simple answer is you can't. At best the video card on your laptop will have two RAMDAC's on it,

RAMDAC - Wikipedia, the free encyclopedia

one will be for the laptop screen and most likely the VGA port, with the other being for the HDMI port only (could also be one for the laptop screen and the other for the VGA and HDMI port). Each RAMDAC while capable of supporting two outputs, they can only use one of them at a time. That is why you can't get all three to work at once.

At the moment the only way to get more than 2 displays at a time with a single video card is the ATI HD 5xxx series of cards that have Eyefinity. Not sure if there are any available for laptops yet, but even if they were it would require a new laptop as it isn't like a desktop where you can just change the card.
