Hey there,
I have a user that is running into a issue with there Photoshop set-up. Right now they are using a LG Ultrafine 5K as a monitor with a M1 Pro. They said that
"The program cannot zoom past 200% without the canvas separating or turning black, this happens on monitor and on laptop without monitor plugged in."
I looked through some other threads on here but couldn't find anything to go on. Any input would be great!
