The second display won't wake up after my MacBook Air M1 goes to sleep with the second display connected with USB-C to HDMI cable.
The same question was posted in Dec 2021 but the answer was useless: it linked to two Apple papers that DO NOT address this problem:

You can get a cable for about 15 quid on Amazon: https://www.amazon.co.uk/Cable-Matters-DisplayPort-USB-C-Supporting-Black/dp/B01LYD2Y19
I checked the monitor specs, so it should all work.
Unless you plan to replace the display quite soon, I would personally find the display not waking quite frustrating…
Good luck.

Thank you for the information. If "DP in" means Mini DisplayPort, I can get a $39.95 cable from Apple Store, or just live with the problem, which happens randomly, and I believe does not happen when shutting down.
Also have you ever wondered why the markings on the back of displays are so difficult to read?
Hello, most monitors have full size DisplayPort on the back, and the only place you'd see Mini DP is on Laptops typically, but if you want to post a link to your monitor, I can check the specs.
With regards to markings on the back of your display, mine is quite unclear too... Easiest way to figure it out, is that HDMI ports are symmetrical, and DP ports aren't.
There is one port at the back of my display (LG 24BK550Y) marked "DP IN". So I guess it's a full-size DP port. The Apple store carries a USB-C to minidisplay cable for 39.95 $. I am wondering if it's worth the time and expense to go hunt for a cable, or just cope with what I have until I get a new display with hopefully a USB-C port. I bought the USB-C to HDMI cable when I got my MB Air to connect to my existing desktop display.
Thanks for the attention.
Hello, if your monitor has DisplayPort, try using a USB-C to DisplayPort cable; USB-C to HDMI cables have to adapt a DisplayPort signal to HDMI, and this often causes issues.
