4K through USB-C

HP Recommended
HP ENVY - 13-ad154nz
Microsoft Windows 10 (64-bit)

Good evening community,

 

I recently purchased a USB-C compatible 4K screen,  and I cannot get the 4K resolution through the USB-C port directly (but FullHD works, although a bit blurry). However, if I put an adapter USB-C to HDMI and connect to the screen with HDMI, the 4K works fine. I had to update the graphics drivers first, but it works. 

I updated pretty much everything I could, restarted a few times but still doesn't work. Also when I am connected directly with USB-C , I tried to go to the settings to increase the resolution: I can select the 4K, then there is the usual "screen update" and a pop-up asking you if you want to confirm the changes, I confirm but it remains on the FullHD.

 

Anyone has an idea?

 

Thanks,

Alexis

How do you connect them ? Please check your adapter/cable.  DP 1.2 should give you up to 3840 x 2160 pixels, at a refresh rate of 60 Hz

 

Regards.

Hi Banhien,

 

Thanks for your answer and sorry for the late reply, the problem is still not solved.

 

I use the USB C to USB C cable from the screen provider. As this is a 4K screen, I have little doubt that it is 4K compatible. As a temporary fix, I now use an USB C to HDMI adapter and it works. I thought the issue came from the graphics drivers but I updated and it still does not work.

 

Kind regards,

Alexis
