I have been having issues to consistently be able to connect two external monitors (both HP Z23n G2 Displays) to my MacBook Pro (Retina, 13-inch, Late 2013) and cannot pin down the problem.
I connect one monitor using a standard HDMI cable from the MacBook's HDMI port to the monitor's HDMI port - this is never a problem. Issue is getting 2nd screen to work. For this, I connect the MacBook via a Thunderbolt connection to the HDMI port on the 2nd monitor, using a HDMI/Mini DisplayPort cable.
The issue is - it DOES work, but unpredictably and sporadically, and only after I restart the MacBook what seems like endless times sometimes. If/when the connection picks up, it works perfectly fine without interruption. If I disconnect and reconnect it, or switch on the computer after turning it off, the connection almost never picks up straight away and I have to go through seemingly endless cycles of restarting the MacBook until the connection does pick up. It's ONLY a problem with the Thunderbolt/Mini Display Port connection.
Really at loss at what to do! The connection DOES seem to work, but I don't understand why it does not work first time and is simply at random/sporadic. I have tried:
- Using a standard HDMI cable (used the one that works perfectly fine with other monitor) with HDMI/Mini Display Port adapter, plugging into the Thunderbolt port on the MacBook. No success.
- Using a Display Port/Mini Display Port cable between the monitor (it has a Display Port connection) and the the MacBook. No success.
- 'Detecting Display' after holding down option and selecting it on the system preferences. No success.
I have ordered a VGA/VGA cable, with a VGA/Mini Display Port adapter - if this combination does not work, I am at the stage of giving up.
Many thanks in advance for reading and/or suggestions! I have wasted hours with this issue!
