Different VGA cable = different resolution?

So I ordered a new (cheap) VGA cable and after I hook it up my resolution dropped from 1680x1050 down to 1024x768.  I wasn't using any xorg.conf.d settings before (but it looks like I may have to).  If I load X with the old cable in place, everythings correctly auto-detected and switching in the new cable at that point  gives me the proper resolution so it should be possible to use the new cable at the right resolution after I mess with xorg.conf. 

Has anyone run into something like this before?  I thought DDC and auto-detecting fixed this.

well, you need to read your edid and see if your cable is too cheap to actually transmit it without errors.

ive got this issue with my samsung 20" too. but i never replaced the cable. it actually stopped working, i forced it through a modeline and kept on with my life

Not exactly funny if you have to load your EDID information via xorg.conf because the cable is too crappy :-/
