Hi Abdallah. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator here to help you.
If it's the monitor only then that could work, but most PC's only have HDMI out so unless your PC has both Output and Input HDMI then it will not work.
To connect the PS3 to an HDMI monitor see here:

I hope this helps. Feel free to ask back any questions and keep me posted. I will keep working with you until it's resolved.
