Both USB-C and HDMI connection to Macbook Air M1 is broken on MacOS Ventura I have recently upgraded to MacOS Ventura 13.1 (22C65) I have DELL P2721Q Display that I use with both 16" Macbook M1 MAX and Macbook Air M1 Recently I have upgraded my M1 Air to Ventura and the USB-C connection to monitor is unsable, the display drops few times every minute making it useless. Also, using Apple's own USB-C HDMI dongle, the monitor is not recognized properly and does not allow me to use scaled option.. also making it useless as texts are too small to work with. On the other hand, 16" M1 Max Macbook Pro works perfectly with the USB-C connection on Monterey Only option I see is to be able to surface it to Apple Enginners and wait for an update to fix it! I don't want to downgrade to Monterey! Let me know if anybody knows any other option.

Mac OS Ventura 13.0 Update now dual external monitors giving me trouble on 2021 MacBook Pro M1 Pro 14" I have a 2021 MacBook Pro M1 Pro 14" and was connected to 2 HP Pavilion 27" monitors (2k/75hz) fine until the OS update. When connected with either USB-C to HDMI or USB-C to Display cables, the monitors rearrange their orientation on their own and my cursor goes in the wrong direction. If I use just a single external monitor, I don't have those issues but have experienced intermittent flickering. Need recommendations on how to get both external monitors to work. It's killing my productivity with work. Thanks!

MacMini M1 & monitors What has stopped me from buying a MacMini M1 is that I keep seeing on different forums that they have problems with monitors. I was planning to buy a LG 27" UltraFine 5K (27MD5KL) and the ASUS ProArt Display 27" (PA278QV) but now I'm having second thoughts. (Apple Display is out of the question) It seems that this problem started with Monterey. Is this already solved with latest OS 12.5? Is it true that the macMini M1 does not support more than one monitor?

Monterey 12.6 shut down second monitor on 2017 iMac 27" using Thunderbolt also. This is UNACCEPTABLE Apple. Now I have to waste valuable time downgrading the OS. I violated my own rule about upgrading too soon if ever.
