Ok, I'll sum this up so I can try and get some help here:
I have an LG 29" UltraWide monitor. The genius that designed it put two HDMI inputs on the back, and that's it.
I have the GeForce GT 740 4GB GDDR5 in my machine, and it works WONDERFUL... However:
Card: Mini-HDMI DVI-I [Dual Link] DVI-D [Dual Link]
Monitor: HDMI [Capable of 2650 x 1080] HDMI [Capable of 2650 x 1080]
Where in the heck does one get a Dual-Link DVI to HDMI adapter or cable? All I need is 6 feet (10 would be better) but I can't seem to find anything. I'm currently using a Mini-HDMI to HDMI cable, and it's obviously not dual link capable, so I've got black bars on the left and right (just 1920x1080).
I've got an active Mini-Displayport to HDMI adapter that I'm using with a Mac Mini 2012, and it outputs the glorious 2560x1080 -- the GT 740 doesn't have display port anywhere, so that's not an option. :\
