Samsung LU28R550UQPXEN
3840 x 2160 Pixels, 28"
I have an HP Elitebook 850 G5 with a screen resolution of 3840x2160. When I connect the Samsung LU28R554UQRXZG monitor (also 3840x2160) via HDMI cable, I only have 30Hz on the monitor. Does anyone know how I can set the refresh rate to 60 Hz? I have already tried many things. I could not configure the frequency in the Intel graphics settings or in the AMD Radeon settings. Hope someone can help me. Thank you.
