Have you tried another adapter?

does seem strange ?   I'm set up that way with a old crt monitor running off the cards dvi-I   with the adaptor you get in the box with the card ??  thing is I don't ever have the 2 hooked up at the same time   ?  hmmmm....    with dvi-I you should carry analog signal native off the card  ?    I don't guess having the hdmi plugged in the card and try to use the dvi-I in analog if the all digital signal  for the hdmi use cancels out the analog part in some way ?  [ I wish I had extra cable to test this out quick ]  reason I bought a 900 series card for native dvi-I analog use for my older monitors

Time to buy a new monitor ---> RE: analog pc monitor

Well.. i tried with another monitor/vga cable and another adapter...Still i get signal on the tv via hdmi but no signal on vga monitor...also i noticed that pc recognizes the 2nd ( vga ) monitor and goes into dual screen mode.When i disconnect the vga it makes tha "device disconnected" sound and it comes up to the hdmi again.When i start up the computer with the dvi-i only i get no signal and sometimes no post sound.Can it be a power problem? i use a 6 to 8 pin adapter to power the card.!??
P.S thanks for the advices guys!!

so i ll have to return the gpu back to the retailer right?

thing I was wondering is if you disconnect everything  [hdmi ]  and only hook up the vga monitor   will it then work ? [all you plug up is the d-sub  unplug the hdmi from the ''card'' ]     what I cant test is if the hdmi is plugged in will it lock out / disable the analog part of things ??
 
seeing how you put this ??
''.Still i get signal on the tv via hdmi but no signal on vga monitor...also i noticed that pc recognizes the 2nd ( vga ) monitor and goes into dual screen mode.When i disconnect the vga it makes tha "device disconnected" sound and it comes up to the hdmi again'' and  ''When i start up the computer with the dvi-i only i get no signal and sometimes no post sound''  ?
 
like me I use one at a time   and then all go through the dvi-I port  as well    and I have nothing plugged in to the hdmi or display ports  ??   thing is the hdmi is all digital  and no anlog support  where the dvi-I is using just analog only  for the d-sub use ??  
 
so just hook up the vga monitor as if it was your only monitor  nothing else ??    [I guess I need to order/ find  a hdmi cable  so I could test this out here ]  hard to work on something when not there for any hands on . 
 
all you could do is try another card  in rma  ?    but  should work  I got 2 hdtv's  2 old crt's and a regular  computer monitor  all work as expected on the 980ti's dvi-I port   I just don't have a straight hdmi cavble to see if using it affects the analog part  of things some how ??  don't seem like it should but todays cards are funny   
 
like here maybe  ?
 
''I'm still a little surprised that this did not work but it is entirely possible that the graphics card only has one set of hardware for converting the digital video signal to analogue VGA and so will only work with one VGA monitor at a time.  This would mean you can use either the VGA or the DVI-VGA but not both.''

looks like he goes on to say if you use 2 digital ports and use a active adaptor from that for the vga  ???
 
and this ??

sorry maybe just bad then    if you get display and post under hdmi you  should as well with the dvi ?    I never tried to run a all digital display like a hdtv   off the hdmi port and a 2ed display  analog  like dvi-I /vga ?   I figured the cards can only do the digital side of things or the analog side of things but not both at the same time ??    like I said I don't have a correct cable to test that out  here ..
 
out side of that   like me I just pull the plug of the digital monitor out of the dvi-I and plug in the vga /dvi-I  adaptor like came in the cards box  for the crt and fire up  alls good to go  all auto detected   works fine and dandy  no mess no fuss other then the cable swap   heck I pulled out a old HP pavilion MX50 15'' crt monitor to see if it worked on this 980 ti and it did  and ran firestrike   on it  for fun
 
let us know how it goes after you exchange the card or what ever you find out  and good luck
