Zotac Magnus One restart issue

I have recently purchased the Zotac Magnus One with i7 3070 LHR. I am using the GPU HDMI out to my 4k TV.

Everything seems to work fine, but, whenever I restart the machine, I do not get any display on my TV. I have to physically change the HDMI cable to the one on the motherboard and only then I am able to see the boot up screen when I hard boot the system.

Once the windows login page is displayed with the motherboard HDMI, only then I change the HDMI cable to GPU HDMI to get the display on the TV. No other way seems to work.

I have also updated the system to the latest BIOS upgrade.

I had also contacted customer care and got the product replaced, but the above issue still persists.

Has anyone faced a similar issue?

Any help will be really appreciated.

Thanks.
