Hey, I've solved it myself. So, short answer - Yes, it works!Detailed answer - I found Verbatim Type C - HDMI cable, which is supporting 4K[NAME], and connected to laptop. Laptop is able to work on 60/120/144Hz with this cable on 2K resolution. So, looks like small Dell DA20 is having old HDMI version, as it doesnt give out more than 60Hz.
Hello folks!I want to clarify, which HDMI version have this laptop ?I'm asking, because i want to connect a 2K monitor and have 120 or 144hz refresh rate. Right now, I'm using 3rd party Type C to Display Port adapter, and I have that 144hz on 2K. But now i need to do some changes, and I want to use Type C to HDMI adapter, and i want to have high refresh rate. So, regarding adapter i will take care, but I need to know, will it even possible to have high refresh rate on 2560x1440 with adapter to HDMI. I had tested that dell original small adapter Dell DA20, and this small guy can't give me more than 60HZ output. So, question to experts here - is it possible to have 2560x1440[NAME](144)HZ video ouput via HDMI on Dell Precision 5550 ?
