Q: Acer K272HUL Monitor not seeing MacBook Pro
Just picked up an Acer K272HUL WQHD display from newegg. I'm getting a no signal error with the monitor when using mini display port to displayport. I've confirmed the and monitor work with another MacBook Pro. My MacBook recognized the monitor but no luck on sending a signal. So must be something with my video card. It's a 2009 MacBook Pro with the NVIDIA GeForce 9400M 256 MB graphics. Any suggestions on what to do next? The link to the monitor is below.

I had the same issue. Here is how I fixed it and I hope it works for you.
I happened to have a mini DP to DVI connector.
I connected the laptop to the monitor using DVI. This worked for me.
This allowed me to go into the monitor settings.
I noticed that in the settings there is a section called DP. It defaults to version of DP 1.2 .
I changed it to DP 1.1 and I then connected the the cable from the mini DP to DP and everything worked.
Hopefully this works for you.
