Dvi to hdmi adaptors not working in gpu to display in monitor

so it needs to be dvi [card] to dvi [monitor]?? or are you doing hdmi [card] to dvi [monitor]? or dvi [card] to hdmi monitor] ??

according to the monitor specs. input is stated as -- Input Connector D-Sub/ DVI-D

I never had any good luck with hdmi plugged in to the card and find it to be kinda flakey at best
 
Monitor had DVI and the GPU HDMI. So I have 2 cables. 1 cable with 1 side DVI and the other HDMI, the DVI side is for the monitor and the HDMI for the GPU, it's not working. I have another cable DVI to the monitor and the DVI to the GPU and it works fine.
