Hello a while back my laptop screen broke so I connected it to my tv with an HDMI core and it was working but then I did something and then the screen stopped showing up on the tv. The half a year later I did something to try and fix it and it was working again. But now just recently I accidentally put my laptop to sleep instead of shutting it down and now it won’t show any display on the tv. I trying buying a new monitor by the same company but still doesn’t show any display. Can someone please help me.
