As i was looking for a new "Gaming Monitor" i found a link to CRU and try my first tests. Installed AMD/ATI Pixel Clock Patcher and CRU, i tested serveral setups and at least 1920x1080 @ 67Hz was the highest working value.

Is there a chance to get more Hz on this setup or i should be happy about the 10% boost and let it be?

The TV display is 100Hz native, HDMI port at video card is HDMI 2.0 , cable is HDMI 2.0 , TV Port HDMI 1.4 .

If you mean you're able to select a higher refresh rate but the TV won't display it, then that's a TV limitation. You shouldn't need the patch if you use a custom extension block and add an HDMI support data block in it.

HDMI 1.4 is capable of 1920x1080 @ 100/120 Hz, but most TVs will not accept 100/120 Hz input. Also, make sure it's not skipping frames at 67 Hz: http://testufo.com/#test=frameskipping

If it can display 67 Hz correctly, then you might be able to get 75 Hz with the "LCD reduced" timing option.
