Configure your workspace the way you want it with support for up to three native monitors via DP/DP/VGA ports.
So I ordered one, and have connected three monitors, but I can only enable two at a time. It can be both of the ones connected by DisplayPort, or one of the ones connected by DisplayPort and the one connected by VGA. Does anyone know whether it really is possible to enable all three at once, and if so, how?
"up to three" means that at least one configuration (dual graphics card?) supports three monitors - that doesn't mean that your configuration supports that. – Robert – 2012-06-25T17:25:26.687
It says "support for up to three native monitors via DP/DP/VGA ports". Those are the ports on the back of the machine I have bought. – matthewk – 2012-06-25T19:04:32.450
Matthew - I'm not sure if you are following this any longer, but here's an update. About 10 minutes ago I tried attaching two monitors using DP to DVI adapters - passive. And it worked like a charm. No need for active adapters. I've been reading up on it a bit, and found that the processor needs to be 3rd gen Intel - e.g. Ivy Bridge. I was running with Intel i5-3550 processor. Which processor do you have in the machine? – Anders B – 2012-09-06T09:35:09.783
It's an i7-3770. You say "two monitors". My question was about three monitors, though. – matthewk – 2012-09-06T13:06:11.637
