Dual monitor now too big on one
I just got a new 4K monitor, and also have an older lower resolution monitor that I use for the photoshop windows (layers, etc). The new monitor looks great, but the smaller monitor now shows the windows HUGE. This only happens in Photoshop and not Illustrator, which makes me think it is not a windows issue. Everything else I bring from one screen to the other looks fine in other programs, but Photoshop no. I've googled a bit and tried different setting in the photoshop properties but nothing has worked. Any suggestions?
