Color not correctly updated on eGPU-connected external monitor after wake-up from standby
-
I have a laptop with an external GPU, my external monitor is connected to that eGPU. In the evening f.lux lowers the color on both internal and external screens to my setting of 2700K. When I'm done for the day, I put the laptop into standby. When I wake it up in the morning, the internal LCD returns to the daytime setting of 6500K, however the external screen remains as it was in the evening - yellowish. To restore its color, I have to exit f.lux and re-run it again.
Before I set up the eGPU, I was using the internal dGPU, with the same monitor connected via an HDMI/DP to the laptop's docking station (Lenovo Mini Dock Plus Series 3), and this problem was not happening.
Hardware:
Lenovo Thinkpad W530 with 1920x1080 internal LCD, internal dGPU disabled
External GPU: Nvidia Geforce GTX 1060 via EXP GDC Beast (ExpressCard version, PTD jumper set to 7s)
External Monitor: LG 34GL750-B is connected to the eGPU via DisplayPortSoftware:
f.lux: 4.120
