Hi I have this Macbook Pro 2018 15inch baseline model. Recently I purchased a 4k LG monitor and I plan to connect it with this MBP together with my older screen which is a Dell 2k monitor.
The setup is connect to Dell with USB-C while the LG 4k is through HDMI. On the 2k display I using default scale while the 4k I am using 2560 x 1440.
Problem now is the OS gets very lag and stuttered if I start to view some 4k videos or coding with VScode. I am really frustrated because Apple claim MBP 2018 can connect to dual 4k monitor without issues right? I hope to solve this issue, thanks
