I have just plugged in my new 32" UR59C Curved 4K monitor, and when using HDMI, I only get 1920x1080. When I use the Display Port, I get the full 4k resolution.
Why is this? And how can I fix it?
I have tried with two different laptop docking stations, A Surface Book 2 and a Dell laptop.
Both can use the full resolution when using DP, it is only when using HDMI there is a problem.
I have also installed the Samsung drivers from the website, but to no avail.
I have another high-res, though not 4k, Dell monitor, which both can use fine with HDMI.
Does anyone have any ideas?
