Does AMD’s AM1 platform support triple monitors natively? No.
Kabini only supports two simultaneous displays
If you plan on using AMD new’s AM1 platform with a Kabini Athlon or Sempron, be aware that triple display output is not supported. I tried it on my MSI AM1I motherboard just to make sure and sadly only two outputs were usable at a time 🙁
So even if your motherboard has DVI + HDMI + VGA, like mine does, you can only utilize TWO of those outputs at once. Not three.
Kind of a bummer, as I would love to drive three displays off of a tiny system drawing very few watts.
QHD etc. on AMD Kabini
I tried connecting my 30″ Dell to my MSI AM1’s DVI port and it definitely does NOT support dual-link DVI, the supported resolutions maxed out at 1280×800 (exactly half of 2560×1600). As far as I can tell, none of the Kabini motherboards have dual link DVI support. 🙁
So if you are planning on using a greater than 1080p display that uses dual-link DVI, like an older 2560×1600 monitor 30″ LCD, you will NOT be able to do it with Kabini unless you have a motherboard with displayport and you utilize an active displayport to dual-link DVI adapter.
On the other hand, if your monitor supports the latest HDMI specs for high-res then Kabini will be able to drive those 2560×1440 displays etc. via HDMI 🙂
