Some games won't recognize higher refresh rates added using the NVIDIA control panel.

can it be the cable or a hdmi limit?

HDMI cables can usually handle up to 300 MHz pixel clock no problem, so unless it's a bad cable, it's more likely a monitor limitation. The monitor probably can't quite handle the refresh rate with those timing parameters. Sometimes playing around with the timing parameters can eliminate artifacts. The timing parameters mainly control how long to wait between each line and each frame, so it's not dangerous to play around with them. Try reducing the horizontal/vertical totals. Reducing the totals will reduce the pixel clock, which reduces the bandwidth required.
