View Full Version : Does the G74SX-BBK7 support 120/144hz output though HDMI?

I have a BenQ XT2420 hooked up to it and it seems to not be able to do 120/144hz at 1080p.
I just want to verify if is that computer that doesn't support it or if it is the cable I am using.

If I'm reading the hdmi spec correct you need a hdmi 1.4 or 2.0 connection for above 60Hz 1080p. And I'm fairly sure your laptop has a 1.3x hdmi output, which means you won't be able to run 120/144Hz.

Yeah, that's what I thought it would be because I tried 4 different cables and there was no way none of them were HDMI 1.4. Thanks a lot.
