I upgraded my Apple M1 Pro to Ventura 13.5.1 and have been experiencing continual issues connecting to my LG Monitor 27UL550.
No signal.
Entering power saving mode shortly.
The monitor after about 5mins keeps on turning itself off.
MacBook Pro (2021)
Just an update for anyone who's suffering a similar issue. I spoke to Apple Support and they seem to have solved the issue 'touch wood'.
Apple icon > System settings > Displays > Advanced > Prevent automatic sleeping on power adapter when the display is off (turn the toggle to 'on').
So far so good and immense thanks to Dinesh at Apple for resolving this and to jdo_apple for the link to Apple Support.

Hi gramatter,
How are you connecting the LG monitor to your Mac? Which connections are you using?
Also, take a look at which configurations are available for your Mac here: MacBook Pro (14-inch, 2021) - Technical Specifications
Take care.
Hi Dorain1,
I've checked and there are no firmware updates for the LG monitor (27" 4K UHD IPS Monitor: 27UL550-W.AEK)

The only software available is:
The issue only occurred after I updated my OS to Ventura 13.5.1 so it seems to be your end.
Please can you provide a solution as this is intolerable.
Hi gramatter,
Thanks for posting in Apple Support Communities.
We'll be happy to help out, but since this began after updating your MacBook Pro you will first want to check with LG to see if there are any firmware updates for the monitor. We did find this link for you to use Get Product Help & Support | LG Support.
If there is anything we can help with after reaching out to LG let us know.
Take care!
Hi 1ssmith,
I'm connected via Apple USB-C Digital AV Multi-port Adaptor - White (Latest Model) to HDMI via the LG lead provided.
I'mnot really sure why the configurations are relevant as it was all working fine before I updated OS to Ventura 13.5.1.
Thanks for replying, gramatter, and that additional info, it really helps! Since you are still having this issue, please reach out to Apple direct for further investigation:
Have a great day and thanks for using the Apple Support Communities!
