Question: 10.13.1 --> scaling problem for external UHD monitor
After I installed 10.13.1 a week ago, I am having a problem for my LG UHD monitor (LG 27UD88-W).
Scaling function is not working.
Monitor works only for few options :
3840 x 2160 (low resolution)
1920 x 1080
1600 x 900 (low resolution)
1280 x 720
with 30 hz option only......
Before 10.13.1, my monitor was working fine with other options with 60hz.........this driving me nuts.
I tried to use switchresX, but it crashes whenever restart...
I did PRAM & SMC reset. Still not working properly....
