[Peter Wollsey] "It seems to me that I "have a laptop with a proper video card feeding a proper signal to a proper professional display"

There is no difference between the results I get from my laptop with MX02 LE and my tower with KONA3."


Actually there is if you read up on your graphics card in the laptop. That card is dithering and otherwise "cleaning up" the video signal. In other words it is masking noise that is in the video to make it the cleanest possible image for output.

This is great when you're watching movies or internet videos off your laptop to a video monitor. You want that image to be cleaned up. But when you're color grading or finishing a project, you WANT to see all that noise, if it's in there.

We discovered this during research to install 27" iMacs in some of our new edit suites. I was going to have them drive 17" FSI monitors via the DVI output, but then we discovered there was all this dithering and cleaning up inherrant to the graphics card. So I'm still going to do the iMacs as editing machines, but we're going to feed them directly to our Panasonic Pro Plasmas just for client viewing.

When it's time to finish one of the iMac projects, we'll switch over to one of our towers running the AJA Kona 3 and LHi cards.


[Peter Wollsey] "No disrespect to you personally Walter - you provide lots of great advice and information here - but on this one I believe you are wrong."

No disrepect taken, discussion is what this forum is all about and you have certainly spent time setting up your system. As I said, I did not know about all the dithering and clean up going on with the graphics card until we started digging into the iMacs which are essentially the same systems as the MacBook Pros.

So any video device that's connected to the DVI output of any of those machines is not going to get the same signal as the video card output of a tower.

And I'm not saying you're "getting away" with anything. If clients are happy with your work and they're paying you, then it works for you. I'm saying I would never do that here.
