I have bought the P650 with the intention of going for triple head.

I have spoke to Matrox and it appears that the upgrade you buy unlocks the capability of the parhelia chip to give you triple head. Another thing to note that is the triple head capability only gives you analog outputs. The upgrade effectively give you the same capability as the P750 but without the fan

The official upgrade can only be purchased from Matrox online, don't know the reason why, but to purchase it you need to enter the serial number of the P650, you pay about 78GBP incl. packaging, and then you get the cables and the software to unlock the card.

This was my impression from the info i have seen. HTH.

Immanuel:
"Option one will very likely not give you tripple view. My best guess it, that the first monitor and the TV will have the same image."
This might be the truth, but Matrox could/should state facts about their products.

yes - just be shure, that you read, what they write, and not, what you asume they write. I don't know, what Matrox writes, but my experience tells me, that if in doubt about product descriptions - then let the doubt count - or ask.

I'm running 4 monitors with a quad Matrox PCI E card, but I've been running 4 monitors for 3 years using 2 dual head cards. Matrox 550 AGP plus Matrox 450 PCI - Works great and not expensive. Hope this helps.

Running Matrox P750 , Pulsar , and Cubase with no problems at all!

I love my martox

cheers
