    Hi. I have a problem with the duplicate display. I have Samsung TV, with HDMI port. I got DisplayPort to HDMI adapter. First, everything worked fine. After that, I had re-installed Windows 10, got the last update and when I want to extend my monitor to TV it won't work. First, I thought it was HDMI adapter, I got brand new one, HDMI cable as well. But nothing changed. When I put a cable in my computer, TV screen shows "There is no signal", but when I remove cable it shows "Check signal cable". I've tried to plug in and plug out cable, adapter, restart the computer, tried other, brand new TV, another monitor, but nothing helped. I've looked all around: on HP website, Google everywhere. I didn't find any working solution. Can anyone have any idea what I should do?
