We have two Dell Latitude 6430u for which we just bought two external monitors P2314H. The laptops have a VGA and an HDMI ports (resolution 1600x900). The monitors have a DisplayPort, VGA, and a DVI ports (resolution 1920x1080).
I tried connecting the laptop and monitor with the VGA port, but I cannot set the resolution to 1920x1080 (the drop down menu goes to 1600x900). I bought an adaptor DisplayPort to HDMI, but this does not work (I don't get a signal out; I tested the HDMI cables on a monitor that has the HDMI port and the cables do work).
Can I connect these laptops with these monitors and have them to work with 1920x1080 resolution? Do I need another adaptor or connector?
Both laptops are running Windows 8.1.
Thank you for your help.
