Help! I use an HP external docking system and an HP 34f curved external monitor for my home office. I plug all peripherals into my laptop with the external docking system USB-C cord. For my work computer (Dell) everything works fine. But for my personal computer (MacBook, 0S Sequoia 15.5) the monitor won't display despite the MacBook recognizing the display. In the Display settings on my Mac I can see the monitor, I can configure how it's arranged, determine if it's the main display, mirrored, or an extension. But the monitor says Input Signal Not Found and it goes to sleep. I can't find any help on the internet for this issue except if the computer recognizes the monitor but the monitor won't display it must be a hardware issue (cables or the monitor). But I know this isn't the problem because I use these cables and monitor all day every day with my Dell. Any suggestions are welcome!
