I have a Macbook Pro and a QHD BenQ monitor here. Should it be supported to connect these two devices using a HDMI to DisplayPort cable (So HDMI on Macbook DisplayPort on monitor)?

For me it just does not work, I tried replugging checking the channel on the monitor and detect monitors, no cigar.

For now, I'm back to my apple monitor, well a smaller one than I had before since someone snagged that when I was away. But I'd rather use the BenQ because when you're not living in a cave the Apple monitors are a strain on your eyes (glare reflection etc.).

Anyhow my question is in the second paragraph.

  • On the MacBook Pro, shouldn't there be a Thunderbolt port? It doubles up as Mini DisplayPort. Have you tried the Mini DisplayPort to DisplayPort? – Brick May 20 '16 at 11:33

I would go from your mini DisplayPort (mDP) to DisplayPort (DP) or go HDMI to HDMI from your MBP to BenQ.

The reason why is that DP (newer standard) supports HDMI (older) signaling quite easily through a passive adapter, while going from HDMI to DP requires active conversion. This is probably the reason it's not working.

I have run into this problem before and what I have found to be reliable is to minimize (at worst) to eliminate (at best) the number of conversions you must do. If your BenQ has a DP connection, I would use its companion technology, mDP to make my connection.

  • Well yes I didn't have an HDMI cable laying around. That's why I tried HDMI to displayPort. Got me a HDMI to HDMI now. Works just fine. – Mathijs Segers May 23 '16 at 11:40

Definitely thunderbolt to thunderbolt. Also my BenQ has HDMI so you could do it HDMI -> HDMI
