Allright, i'm trying to use my new 4k monitor with my old one (1080p). Premiere, After Effects, Indesign and Illustrator works fine, but Photoshop doesn't! When i open the program, it runs fine, the problem starts when i open some project. It takes so much to load, if i try to move something gets laggy and the menu starts flickering.
The thing is, it only happens when the program is on the 4k monitor, if i drag to the 1080p works fine! Here some example: https://youtu.be/PyoQJPS__PQ
I've already tryed everything i found here in the comunity, changing nvidia panel settings, the compatibility on windows, changing HDMI cables, uptating my card drivers, using only the 4k monitor.....
My specs: Windows 10 Pro Asus ProArt 27' 4K + Acer Full HD AMD Ryzen 9 5900X 12-Core Processor 3.70 GHz (doesn't have video) 32,0 GB RAM GEFORCE GTX 1070 Asus ROG Strix B550-F Gaming
Obs: My 1080p monitor is "scaled up" to 3840x2610 to use the "extend mode video" properly.
