WMC resolution different than that of desktop

I have black bars around WMC, whereas on my desktop using the ati4200 integrated graphics and catalyst control center I have stretched the desktop to fit the screen. My questions here are why doesn't WMC recognize the desktop resolution? How can I make it stretch to fit the screen? This is my first experience with ATI as I usually use nvidia products. I must say that ATI has NVIDIA beat on the htpc front. (this is my opinion)
As always any and all help is much appreciated

Hi,

I had the same issue, assuming you are using a different resolution for MC and the desktop.
I have an ATI 4550 with CC.
In CC set up two profiles, one for the desktop resolution and one for the MC, stretching the screen size for each one. I set them so they could be launched from desktop icons, orignally thinking I would have to manually activate each one when I switched resolution. However, somehow CC remembers each setting based on the resolution being requested either by the desktop or MC. So when I activate MC I not only get the correct resloution (as selected in MC) but also the screen is filled.

I hope this works for you.
