Hello, I have a Mac Pro 2009 upgrade to 5,1 with 32gb ram and dual 3.06 cpu. The graphic card is Gtx950 with nvidia web driver.
Monitors set: I using dual monitor,First is a ASUS 27' 1920*1080 another is a 4k Samsung 28' but just using 2k resolution 2560*1440.(scaled)
The issue: The Asus monitor is working good but the Samsung monitor is very lag when I use Photoshop ,Sketch even Chrome devtools.If i adjusted the Samsung monitor to default resolution 1920*1080(I don't know why the default is this and how to change it), every thing will work well. But if I change to 2k or any scaled resolution the lagging will be back there.
My questions:
1. Does any one can give me any advice for fix it by software setting?
2. Should I change to a AMD graphic card like rx560 to fix it?
3. Or change one of the monitor (Please note the model) will get it done?
Thank you for any help!
