Monitor: HP Z24n G2 Show
MacBook Air M2 operating Sequoia 15.2 (difficulty was current in earlier sequoia variations)
USB-C hub: UGREEN Revodok Professional 313
Monitor-hub connection methodology: HDMI to HDMI
MacBook energy supply: MagSafe cable linked to a 3-port, 65W Anker brick. Does not undergo the hub.
Situation description: the monitor randomly disconnects from the clamshell MacBook as if the HDMI cable was disconnected. The difficulty can generally be solved by key presses, mouse clicks, cable disconnections, however not at all times. The one certain repair is to open the MacBook lid and the monitor will reconnect. That is fairly inconvenient, as I used to be contemplating shopping for a laptop computer shelf to tuck it below my desk. Situation was additionally current with an older DELL monitor I used, paired with the identical hub and peripherals, however with a USB-C to VGA cable.
I have not managed to breed the problem nor repair it. The ability brick, which I take advantage of to cost each my MacBook and my cellphone (fast-charging disabled) forwards 45W to the MacBook if each units are linked to it. I’ll now cost my cellphone elsewhere to find out if it is a energy difficulty, however I consider not, as it is a recurrent difficulty and my cellphone is not at all times charging.
I can’t but take a look at if the problem lies within the hub, as they’re fairly the costly merchandise to purchase for the sake of troubleshooting.
Essential observe: this occurs throughout energetic use, normally when opening apps and minimised home windows or toggling full-screen.
Any identified fixes for this? Shopping boards did not present one which took a precise root trigger into consideration.
