I have a Sapphire Radeon R9 270X 2GB GDDR5 graphics card and a Asus VE228H monitor. I recently bought a Dell E1914H (which is a VGA only monitor) along with a VGA to HDMI converter (and a HDMI cord). I set it all up (HDMI in the graphics card, hooks up to converter box w/ the VGA which goes into the monitor) but it isn't being recognized... help?
