I have a late 2008 macbook (2.0ghz core 2 duo, 5gb ram, nvidia geforce 9400M 256MB)

 

I also have a 30" monitor running at 2560x1600 connected to it. The peformance of the system with the external monitor is quite slow (scrolling, launchpad, mission control, youtube).

 

How well will it run on the Intel 3000 HD or 4000 HD?

 

What do I need to be able to full screen 1080p video on the 30" and get smooth performance.

    That would depend upon which Application or Game you will be running. The Intel HDs use memory sharing with the CPU and the more intense the CPU usage is the less is left for the Video Processor. The max usage is 512MB.

    I have the late 2012 mini (16GB ram, SSD) and am using at Dell U2711 (2560 x 1440) connected using the displayport.  Looks great, responsive, no issues in iPhoto, iMovie, etc.  Mission control, launch pad, etc. works flawlessly.

    Sorry to hijack this post but I was looking at getting a Mid 2011 Mac Mini to run with my Dell U3011 30" monitor running at 2560x1600. Are you saying that I can use a Mini DisplayPort from the Thunderbolt port and then go to the DVi or DisplayPort of the monitor to achieve full resolution?

    Alan - I believe your Dell (like mine) has a display port out.  You can get a cable that has a display port on one end and a mini display port on the other (which plugs into the Thunderbold jack on the mini).  Remember to go to the Dell menu to tell it you will be using the display port output (some forget this step!) and your mini will use the higher resolution.  I bought this cable from amazon and it worked like a charm (no local retailer carried one):

    Best of luck!

    Perfect. That's what I was hoping and yep, I've already got one of those cables as that's how I currently connect my MBP to the Dell. Thanks for getting back to me.
