You do not need an adapter. You only need the provided HDMI to HDMI cable that shipped in the S2421HS box. Nvidia GeForce GTX 645 HDMI out port #12 in picture =[IMAGE] S2421HS HDMI in port in #4 picture =[IMAGE]
I have an XPS 8700 Desktop computer that I bought in 2013 along with the monitor. The monitor died a couple of weeks ago so I ordered a new monitor from Dell S2421HS. The new monitor has an HDMI cable (both ends) but the old monitor had a VGA plug at the end of the cable from the monitor that was then plugged into a DVI plug that was then plugged into the desktop. I have tried many things to get the monitor to work based on talks with Dell's support. It was suggested that I needed a DVI adapter for the HDMI cable – that didn’t work. Then Dell support suggested I needed a DP adapter (plug it into the monitor and then the HDMI cable into it and then the other end of the cable is plugged into the HDMI port on the desktop computer – that didn’t work. Any suggestions?
