Hello, So I just bought a Qnix QX2710LED monitor that supports 2560 x 1440 resolution. When I hook it up to my late 2010 iMac and go to Display the only option it gives me is 1920 x 1080, does anyone know why? My iMac has a ATI Radeon HD 5670 512 MB and on NewEgg (the online store I bought it from) it says that it 'suggests NVIDIA: GTX460 or more than 1GB memory, with DVI-D Port; ATI: HD6850 or more than 1GB memory, with DVI-D Port' does this mean that my graphics card doesn't support a DVI-D port? I tried to look up information on it but I'm lost. Please help! And if it's an issue of my computer not being able to handle it do you have any suggestions on another 2560 x 1440 monitor (thats relatively cheap) that would work?
