Laptop freezes when connecting HDMI to 4k tv

HP Recommended
Envy x360 - 13y023cl
Microsoft Windows 10 (64-bit)

Please help!

I have a HP ENVY x360 - 13-y023cl laptop that has a 4k display. Everytime I try to connect my laptop to a 4k TV using an HDMI cable it causes my computer to glitch out. The screen starts flickering/freezing up and eventually my laptop will crash and blue screen and have to restart. It only happens with 4k TVs/monitors, I have connected it to many 1080p TVs and it works just fine. Also the 4k TVs never receive any signal from my laptop. I've tried updating drivers but either I didn't all the right ones or it didn't help. I don't know what else to try.


Thank you!

A couple of resources for HDMI and 4k


Does it work?

Can HDMI Support 4K?

and, from the same people,

What kind of HDMI cable is needed?

Is HDMI 2.0 Needed for 4K?
