Your issue is definitely not a cable issue. 1280x720 @ 120 Hz is still under 165 MHz, and most HDMI cables can easily handle more. What timing parameters are you using?

This is typically what HDTVs use at 1280x720:

H: 1280 110 40 220 370 1650 +
V: 720 5 5 20 30 750 +

If that doesn't work, the TV might not support 120 Hz input. Most TVs are only designed to handle 60 Hz input, and 240 Hz is likely just 120 Hz interpolation with backlight strobing.

You might actually have better luck if you try 1920x1080 @ 120 Hz instead. You will have to use CRU to import this file first: https://www.monitortests.com/hdmi-audio.dat

Then enable the extension block and reboot.

Okay. Looks like my TV most likely does not handle 120hz properly as I just tried those settings you gave me at 1280x720 and it still does not work. Out of curiosity before I give up, could you please tell me what the ideal settings should be at for 1920x1080? And regarding "timing parameters", forgive me, but I have no idea what that means?
