olde 55b6p 120 mhz 2556x2080

I tried 2560x1440 @ 120 or 100Hz with a GTX1070 but my 55C7V shows an animated message about unsupported input format and the card/driver often fails to recover after the timeout (even the secondary DVI-D display remains black).

I similarly couldn't make NVCP to list 10+ bit for 1440p60. HDR10 works with dithered 8-bit but that's far form ideal. In that case, I would be better off with sticking to 2160p60 8-bit and let the game engine or the GPU resize the 1440p render resolution to 2160p output.

So, all in all, I could never make any unofficial mode work on the LG C7.
