XPS

[dynamixyang]

Hi,

I have a DELL XPS 15 9570 i7-8750H which has a UHD630 graphics card. I connect my XPS to a 4K monitor LG 27UK650 via HDMI 2.0 and the XPS can output 4K@60Hz with any version of drivers.
Since I update my UHD630 graphics card driver to 24.xxxx or 25.xxxx, I found that if I turned on the HDR&WCG option in Win10 1803 settings, my 4K monitor LG 27UK650 seems can't properly receive 4K HDR signal, and the screen just goes black.
However, the 23.20.16.4973 driver at 2018/2/28 doesn't have this issue.
Is that a bug or something? My colleague whose Vostro 15-7580 i7-8750H with 24.xxxxx driver seems doesn't have this issue.
