Hi, I have bought an external monitor (ACER KA222Q) to use with my Macbook pro.

Using a HDMI cable to USB C (4k).

Day 1 it worked fine immediately

Day 2 it took around an hour of mostly saying no signal but flashing on and off then worked at 720p - 50 hertz

Today it took about 2 hours before it stayed on at 480p. After it has been on a while I can increase it to 720p then 1080p (over the course of an hour or so) and now it works at 1080p fine.

What is going on?? Do I need a better cable?

It is an issue with my graphics card - Intel Iris Graphics 540 1536 MB?

    @Linz008

    Are you using the USB-C to HDMI adapter that has the male HDMI connector?

    Try to plug the adapter into different USB-C port.
