G55VW or G75VW 4k output 60hz with display port? What type is the display port? 1.2?

Hi,
I'm retiring my baby (g55vw) in about 3 months but it still runs as good as day 1 (save for some dents, a non functional battery and not working headphone jack)
I read that the 660m (not 670m) got an update driver later on to support 4k till 60hz by Nvidia.

Sure enough, people here have run it at 4k at 30hz using the hdmi port! But it seems no one tested the minidisplay port (understandably as it was expensive back then to get a minidisplay to hdmi 2.0 cable).

I just purchased a nice 4k 60hz monitor, and was wondering if I get a mDP to hdmi 2.0 adapter if I can output at 60hz?
It should depend on the display port model, so I'm wondering if it's 1.2 or higher (1.3 works!).

Thanks!

For example this claims it'll even do display 1.2 to 4k 60hz.
Dunno how that works given bandwidth limitations of 1.2, but I could be wrong.

Bump, does any mod know?
Thanks

I know it's been 5 years. Did this ever work? 😅

PS: If you didn't already know by now, 1.4a supports 4k 60 directly, but only at chroma 4.2.0 which is not ideal.
