does hdmi capable monitor make a difference?

i have this problem and i wonder if anyone know the answer.

i have this gtx 670 videocard which have hdmi output. i use this hdmi port and hdmi cable to send signal to my onkyo receiver. and i have a asus monitor with HDMI support and gtx 670 have dvi-d display port. my display cable have two different end. one end with dvi plug and other end is hdmi. so i use the dvi out from videocard and hook the hdmi end to the asus. so everything work without problem.

here is a weird problem that i might think that this new monitor dont have hdmi support maybe the issue.

so i bought this dell s2340m monitor and which dont have hdmi support. because of non hdmi support so i have to use display cable with both end dvi-d. the display would be fine. but when i hook my hdmi for the onkyo receiver into the videocard. the desktop screen disappear and icon is gone and the monitor still show my wallpaper but it a bit zoomed out. and i can't do anything. it a very weird problem. but if i unplug the hdmi from the receiver it return to normal desktop...

and if i uninstall my nvidia drivers and i dont have that problem so i guess is that after installing the nvidia drivers it cause that problem.

anyone know why is this? any work around for this?

and i am using the beta 313.96 driveres atm.
