How to connect nvidia geforce gtx560 to a LCD monitor?card is having only HDMI plug..?

well if your monitor is full hd alreayd? you only need the HDMI plug if you want the HD audio etc, but if you have good speakers then it wouldnt be a problem :) and if you DONT have a DVI port...and that you must us HDMI, go buy a HDMI to DVI connector :) and that would solve your problems easy!
