Please Help! Dell 14 7000 fail to detect a particular monitor

I have an Asus VS238H-P monitor, a Dell 14 7000 laptop ( windows 10 with Intel HD 620 Graphics), and an HDMI cable.

When connecting through HDMI, the Dell laptop cannot detect the Asus monitor.

(I have tested the laptop/monitor with other monitor/computer and they both worked fine with other monitor/pc)

I have checked the drivers and everything is up to date...

So... do you guys have any idea of what could be wrong?
