Hi, I have recently installed Sonoma 14.5 (23F79) on my Late 2013 iMac (14,4). I have an external TV (FUJICOM 32″ LED TV, Model: FJ-32X400, with native resolution: 1366×768) connected to my iMac via an Apple original Thunderbolt to HDMI cable. Since the OCLP install of Sonoma (from Catalina) to my iMac, I started to have small disconnects between my iMac and the TV. Initially it was for few seconds at a time, usually in the morning when i start working on my iMac. Now it looses connection entirely as soon as I wake my iMac up in the morning (just press any key on the keyboard to wake it up). I need to restart it several times, plug and unplug the cable, try switching from HDMI1 to HDMI2 on the TV, and eventually I can get it to work, but its super frustrating as I never had this before.
Any idea whats going on here and how I can fix this?
BTW, after the Sonoma install, I had issue with fuzzy font on my TV, I installed Better Display, which made the iMac built in display super sharp and made some (but not great) improvement on the TV. Since I started having this disconnect issues with the TV, I removed Better Display, as part of the troubleshooting, and seems that font is now not too bad on both displays.. strange.. (I did not install Better Display back).
