I capriciously scooped up another Korean QHD panel on sale because it had an HDMI port and therefore - at least I thought - I could finally jettison the Dual-Link DVI issues that plagued my old one. Little did I realize that my knockoff mDP to HDMI cable was only going to send at 1080P. I'm not sure if this is a limitation of the cable or my drivers. I have a mid-2012 MBA with the Intel HD 4000 card. Is there a more robust Thunderbolt->HDMI cable out there (or possibly updated drivers) that would allow me to send QHD across the wire or am I going to have to shell out $100 for another crappy Dual Link DVI cable?
