HDMI Out not working with Dell LCD

[KParacha]

Hello,

My HP notebook (HP Notebook 15-dy1751ms) is not detecting a Dell LCD (Dell ST2220L) via HDMI cable but my notebook is detecting my LED Television via the same HDMI cable, so it means there is some combability issue between my notebook and the Dell LCD. I have already done the following:

• Connected the same HDMI cable with another notebook and the display is fine. Means, both the cable and display are working fine and its just some issue between the Dell LCD and my notebook
• Updated the BIOS and the Display Drivers

Any help will be appreciated.

Thanks!
