I have the exact same problem. I switched from nvidia to ati and I no longer can create custom resolutions from the cc. The thing is, I used to have an nvida videocard and in the control panel I could create the wanted 75hz. I got the 840 x 1050 even with the nvidia card if I didn't set the timing standard as CVT reduced blank.
I just can't get it to work with the edid editor. always get only half of the horizontal resolution. If the CVT isn't on there are blank frames between frames which is too much for the display ( the 75hz alone is pushing it ).
I have ati radeon now and in the control panel there is the option to "reduce dvi frequency..." but no luck with that either.
Read somewhere that edid v1.3 does not contain information about CVT because CVT is new and v1.3 is not.
So anyone know how to tackle this?

( I wish I still had an nvidia card... )

IN the CCC go to desktops and displays, lower corner right click the monitor your using (choose configure) it goes to DTV HDMI 3. See if you can force the resolution under HDTV support. In there you will find all that you need to adjust everything.....

Sorry. I've been away. How is your monitor connected to your video card? DVI? HDMI? VGA? I need to know about any adapters or KVMs as well. Best case is to connect your monitor to the card directly using a digital signal path like DVI or HDMI and NO ADAPTERS! They don't work.
