4K DISPLAY PORT RESOLUTION HD 530 HIGH SIERRA

[kribbio81]

Hi I have a problem, about 1 year ago I was able to run the first Sierra version with my 4K 3840x2160 resolution monitor then after 1 year I installed High Sierra and this problem. if I connect the HDMI cable it all works with the maximum resolution of 1920x1080 if I connect the display cable to my first black screen and then reboots. I tried installing the latest version of Sierra with the same black screen results and reboot if connected with port display. I can not get the maximum resolution with HDMI at 3840x2160 and my motherboard supports 4k.

I have the exact same issue, but on an i3-6100. I have just ordered an i3-7100 hoping hd630 will fix the problem. I'll let you know tonight.

I anyone else has any working solutions, that would be greatly appreciated, since going back to 1080p is an eyesore
