HD 4400 and UHD 620 doesn't output on HDMI

I think you delete my previous post, but here I am again, because this is an intel issue, not a manufacturer issue....
I have two laptop, one with HD 4400 and another one with UHD 620 + a discreet gpu nvidia mx 150. both laptop doesn't output any signal through HDMI on 4 tv and 1 monitor.
Both hdmi works, because on a Samsung monitor Full HD both laptop works.
And there is no problem with TVs 'cause another laptop with an old ATi Radeon Mobility can output on every single TVs or monitor without any issue at all.

So I think is a driver related problem, maybe should I install a specific driver version? on win 10 1903? because manufacture does not support this win version.

thanks
