4K Resolution Refresh Rate

[mohayeji]

Hi there,
I bought a new 4K monitor yesterday (LG 32UD59) and attached to my ASUSPRO B9440UA laptop.
(CPU: Core i7 7500U - VGA: Intel HD Graphics 620 - RAM: 16GB)

My display on the monitor is laggy, I was checked the refresh rate, Max rate is 30Hz & I can't increase the refresh rate to 60Hz.
I'm using the original manufacture HDMI cable.
My Display Driver version is 24.20.100.6286 on Windows 10.

Help me, please.

Your laptops HDMI port probably isn't capable of outputting 4k 60hz. Check which version HDMI you have, I believe HDMI 2.0 is required for 60hz.

^+1, your integrated graphics don't (natively) support HDMI 2.0, which is required for 4K/60Hz.

"HDMI 2.0 however is still only supported with an external converter chip (LSPCon)."
