I have a LG TV recently unless I switch on the PC with HDMI connected the TV does not "see" it.

Same thing happens when the PC has been on for a few hours  the TV does not "see" it unless I restart the PC.

Tried using a HDMI splitter no luck.

Checked the TV to make sure firmware is up to date.

Power settings on the PC are to never sleep or save Power.

Windows 10 issue or something else?
