I'm evaluating the iMX6Q to see if it fits our needs. One of them being the need for supporting 1920x1200 on the HDMI output. It doesn't out of the box, but after some searching on this board it seems that you can add your own resolutions to ./drivers/video/mxc/mxc_edid.c. But is this going to work ? Or is there some kind of hardware limitation which will make this not work ?
You are correct, you can set your own resolution and yes, it does support 1920x1200 on the HDMI output.
