[SOLVED] Second display on 30hz.

[Skafec]

Hey guys. So i got a laptop for work, exact model is HP 650 G5 with specs:
CPU: 8th Generation Intel® Core™ i7 processor (i7-8565U)
RAM: 16GB
Storage: 512GB SSD
GPU: Intel® UHD Graphics 620

Right now I have my sencond screen connected via HDMI. Second screen is Dell UltraSharp 4K (U2718Q).

I noticed that my second screen works slower than laptop one and decided to check refresh rate. It was set to 29 Hz and I couldn't change it to 60. Is it possible that GPU doesn't support HDMI 2.0?
What should fix this issue?

Thanks in advance.

Intel HD graphics don't support HDMI 2.0.

Yeah thought so... Is there no other way to have 4k 60Hz secondary screen?

Does your laptop have a displayport output?

Does your laptop have a displayport output?

Full list of ports:
2 USB 3.1 Gen 1 (1 charging); 1 USB 3.1 Type-C™ Gen 1 (Power delivery, DisplayPort™); 1 RJ-45; 1 headphone/microphone combo; 1 HDMI 1.4; 1 docking connector; 1 AC power; 1 VGA or Serial Port (Cables are not included.)

Mine has Serial Port and not VGA.

Now I see that Type - C can be used as DisplayPort. Could this work? If so, is there any special cable for 4k @60Hz?

Yes, just use a USB-C to DisplayPort adapter: https://www.amazon.com/Plugable-USB-DisplayPort-Adapter-Resolutions/dp/B01EXKDRAC/
