Using USB to HDMI cable?

Hi…I’ve just installed Kodi onto a Laptop I have, and all is working fine. My only problem is that as it’s quite an old laptop there is no HDMI port. Would a USB to HDMI cable work ok?

I also want to plug it in via my Denon AVR to (hopefully) get the audio through my home cinema speakers? Is this possible?

I’m new to this so apologies if the questions sound a bit dumb!!

Thanks and regards,
Clive
