What Video card for Hybrid CrossfireX on a M4A785-M Radeon HD 4200

Sorry the onboard 4200 currently is only compatible with 2400xt, 3450, and another 3000 series card. There is no expectation presently for the 4200 to work with any other existing 4000 series dedicated cards. The shader levels at the least are not compatible. Also when you plug in the 4870 I believe the bios should automatically disable the IGP 4200 due to the incompatibility.

I believe your looking at the onboard 3xxx series information. That's all I can find. There isn't even anything about the 4200 or 785g on amd's website. I did see that it's a dx 10. I managed to get it working by making it the default video device when I boot up. Right now I have it going to my TV and my 4870 going to my LCD. If you have any sources I would appreciate it.

Funny thing is it says "Hybrid CrossfireX" on one of graphics on the back of the box. It's probably a misprint.

I just bought a gigabyte that said the same thing, it looks like they got the wrong information from AMD

Just found this on one of AMD's pages.

went to the site you gave me and that is correct, both AMD website and the Gigabyte both say they are hybrid compatible on the 785 chip set with HD 4200 but on an earlier response some one mentioned that AMD said it was not supported. I just wanted clarification if they supported it. I am just building a media center PC so this Hybrid option looked pretty good. If I thought the on board graphics wasn't good enough I could always add a graphics card to help out. I read that on some systems it increased the performance of the card by up to 40%. But the catch is only certain cards are supported and I have not been able to find a list anywhere. I am trying to keep the cost down since I am just going to do some streaming.

does anyone know if a graphics card support list?

I also contacted Gigabyte for clarification and am now waiting for their response.

Again, here's the response I received from AMD... FYI, the 4200HD gave me a 4.1/4.0 scores of the graphics section on the windows experience app.
