> which pin complex is DisplayPort and which pin complex is you HDMI ?
I don't know how to figure this out. According to what you pasted, control.6 is DELL U2410, and control.12 is LG TV. Physically, DELL U2410 is connected to the DVI port using the DVI-to-HDMI cable, and LG TV to the HDMI. DisplayPort is unused.
> but your new motherboard does not have dual HDMI?
It sort-of does. It has one DVI connector that is seen as HDMI1 by xrandr and is actually connected to an HDMI encoder. Also it has a "real" HDMI connector that is seen as HDMI2 by xrandr. And it has a DisplayPort.
Also the old motherboard physically has one DVI and two HDMI sockets, but, from the software viewpoint, all three are HDMI. And actually, with the old board, the Dell monitor could produce audio clicks even when connected to the DVI output using DVI-to-HDMI cable.
So, in both cases, please treat the DVI physical connector as HDMI.
