The part about pixel clock limts in the first post explains why you aren't able to get higher resolutions. The EDID only has an HDMI data block with the max TMDS clock set to 225 MHz, so the driver ignores anything above that.

The manual says the TV has an option in the Setup menu called "EDID Switch" with two options: EDID 1.4 and EDID 2.0. They actually mean HDMI 1.4 and HDMI 2.0. Try setting that to 2.0 and see if that solves the problem.

I have tried EDID 2.0 before with no luck.
Ran that patch, was able to set 1920x1440. Then tried 2560x1440 with no luck.
