Hi, I bought a 60Hz BenQ BL2420PT 23.8" 2K resolution IPS monitor.

It has these inputs: D-sub / DVI-DL / DP1.2 / HDMI1.4 / headphone jack / line in

My VGA is a GTX760 Mars (dual GPU card)
Link: https://www.asus.com/au/ROG_ROG/ROG_MAR ... fications/
It has these outputs options.
DVI Output : Yes x 2 (DVI-I), Yes x 1 (DVI-D)
HDMI Output : Yes x 1 (via DVI to HDMI adaptor x 1 )
Display Port : Yes x 1 (Mini DP)
HDCP Support : Yes

I have read that HDMI doesn't like resolutions over 1080p (or simply can't display it over 30FPS) and my VGA doesn't support D-SUB.

So, if I use a mini display port cable to display port (like the cable in the link below). Will I get the optimal feature set of my screen?

I did buy a different brand of such cable from a different retailer but it was a cheap low bandwidth version that doesn't support 1440p so I have to return it. And I don't want to risk losing money on shipping this time around.

Another question about the monitor.

The monitor has the option for 'USB upstream' and/or 'USB downstream' as an input option (as shown in the quick setup guide) and the packaging came with 1x Cable that was USB on one end and what looks like mini display port on the other end - to support this feature. But what in the world is that for?
Saying that, there is only ONE port for this odd 'USB Up/Down stream' so I don't know if you get BOTH up and down stream or have to choose one of them after plugging in that weird cable. Thanks for the help on this one.

Basically what I am asking is. Does a mini display port to display port cable give the exact same bandwidth and performance to the monitor as a display port to display port cable would? Thanks.
