Lenovo x1 Carbon Gen8 HDR with LG C3

[exznomak]

Guys I've spent troubleshooting a week and still can't play HDR through my laptop. Spent a few days on different HDMI cables before checking my laptop specs and finding out that it has 1.4 hdmi port  and not 2.0 as required by spec.

My laptop has 2 Thunderbolt3 ports, which was my next attempt, and I was sure it was going to work easy. I bought adapter (Ugreen 70444) which says supports 4k60 and uses VL100 chipset. 

Using adapter and good cable Windows still doesn't recognize my C3 as an HDR supported display.

 

I tried latest GPU driver from Intel and latest driver from Lenovo, nothing changes. 

Also the Thunderbolt 3 app doesn't detect anything while adapter+cable are connected(Should it?)

 

I have  collection of blurays ripped to my NAS and jus't cant wait to watch the 4K HDR LOTR.

HELP!

 

I hope this is somehow fixable and I dont need new computer!
