Raspberry Pi 4 No Signal HDMI

Thu Jan 16, 2020 3:07 pm

Hello,
I just bought a raspberry pi 4 4gb ram and im having trouble putting it to work on my tv(Samsung ue55nu8005) in 4k
it works OK in 1080p but with some red dots on the screen. i've tried the hdmi boost but no luck.

I'm using official Hdmi cable and power supply.
