Spectre X360 4k External monitor

[thoracicnerve]

my laptop is HP spectre x360 w000tu. yes it has thunderbolt3 port.

I at first tried usb c to HDMI(definietly ver.2.0, both gender and calbe are 4k 60Hz compatible) gender to display 4K on my 4K MONITOR which only has HDMI port and is actually TV

BUT IT ONLY DISPLAYED 1920x1080 60Hz....

Then I found this on the w000tu Maintenance Manual

USB Type-C port — (2) USB 3.1 Gen 2 with Thunderbolt™ Gen 3 technology
All ports support data transfer, power delivery, and HDMI 2.0 out up to 1920×1200 at 60 Hz

And This

 USB Type-C ports — (2) USB 3.1 Gen 2 with Thunderbolt™ Gen 3 technology
All ports support data transfer, power delivery, and DisplayPort 1.2 out up to 3840 × 2160 at 60 Hz

So I tried

USB C TO DP gender + DP TO HDMI conversion cable  connection to my 4K monitor (All are 4k-compatible components and each are vaild according to reviews)

Eventually THE MONITOR SAYS 'NO F***in SIGNAL', 

So my question is

--------------------------------------

1. How can I connect my Spectre X360 w028tu to 4K monitor in 4K resolution.

2. Please Help me... 

Thank you.

Does the external monitor not have DP?

Manual: http://h10032.www1.hp.com/ctg/Manual/c05357578

As you've already seen, HDMI 2.0 out is only up to 1920×1200 at 60 Hz through all the USB Type-C ports.

Actually, It is 4K TV...

What about USB-C to DP adapter, through which you can connect to 4K DP port?

HP has not listed any compatible HP adapters add of now though.

I see that you have edited your thread starting post like this:
"to display 4K on my 4K MONITOR which only has HDMI port and is actually TV"


My answer is still the same: you cannot out put 4K HDMI video from any of the USB-C ports of this notebook as they do not support 4K output in any manner.

I also noticed you've started another thread with the exact same query.
