Asus TUF Z370-PRO GAMING Intel UHD 630 HDMI out problem

[tcorp]

Hello,

While connecting a monitor to the Mobo using the integrated Hdmi out the picture is messed up and flickers all the time.

I've tried several Hdmi cables but I've got the same results.

The problem occurs in windows and also in the Bios

DVI port works just fine but it is limited to 1080p.

The monitor works great with other pc and laptop.

Here is a video of the problem:

GPU diagnostic attached:

Please help me to figure out whether the problem related to the iGPU or to the mobo?

My setup:

Asus TUF Z370-PRO GAMING - Latest bios 1003

Intel Core i5-8400 Processor (Intel UHD 630 integrated gpu with latest driver 15.60.2.4901)

Windows 10 x64 with latest updates

Philips BDM3270 Monitor (Max resolution 2560x1440)

Thanks in advanced,

Tulip
