If you have a HD4000, this should do the trick for you, however if you use HD5000, there are problems with both YUC and RGB output:
YCrCb: yep, you get BTB and WTW, but the colour is wrong (ATI did RGB/YUC conversion producing wrong colour which is different from HD4000 YUC is output untouched IMO).
RGB: The luma is wrong, and it produces more banding than HD4000. The luma output is strange - 16-232 according to my measurment.

Ummm, the answer to all that is to avoid HDMI like the plague.
If you use a non-ATI DVI to HDMI adapter I think you avoid all that rubbish, you certainly do if you run VGA.
