Based upon the DisplayPort (DP) 1.2 standard, 144Hz should be possible. 240Hz slightly exceeds the bandwidth limit and may or may not work.

The processor is G4600 and the motherboard only has HDMI, DVI and D-Sub.

Well, that changes things...

 

  • For VGA (D-Sub), you will be limited to 60Hz.
  • For Single-Link DVI, you will be limited to 60Hz.
  • For Dual-Link DVI (if supported), you will be limited to 120Hz.
  • For HDMI 1.4, you will be limited as follows: 720p: 120Hz, 1080p: 144Hz (240Hz maybe), 1440p: 75Hz (144Hz maybe), 2160p: 30Hz (75Hz maybe).
  • For HDMI 2.0 (if supported - but doubtful), you will be limited as follows: 720p: 120Hz, 1080p: 240Hz, 1440p: 144Hz (240Hz maybe), 2160p: 60Hz (120Hz maybe).

 

If nothing else, it was educational digging out this information,
