Hello,

I own CB270HU Acer External Monitor in combination with MacBook Pro Retina 2015 & I use HDMI cable to connect to the monitor.

 

The monitor is acting crazy - the signal is continuously being interrupted, it's blinking, flashing and making very unhealthly noise. To some extent, this had happened since I bought the monitor around a year ago. But most of the time, it was just one or two blinks and then it worked well, so I couldn't even reproduce the problem to catch it on camera.

 

Please, take a look at the video I took to make it clearer: https://youtu.be/klfOreEsB_M

 

I found out that:

- The Computer is not the cause (I checked windows laptop as well)

- The HDMI cable is not the cause (I used three different cables)

 

Do you have any suggestions?

Thank you.

    If you tried different cables and computers and it still blinks/flashes, we would recommend repair at this point. If the monitor is in warranty please contact Acer support from this link:
