Connection to Promethean panel through HDMI port

[Jennymcd]

Hi,

We have recently gotten interactive panels for teaching with in our schools. All computers connect through HDMI port except mine. Mine is a HP 15 with windows 11. Most times it doesn't pick up the HDMI connection at all, other times it does but it crackles and cuts out. I've checked the duplicate screens setting and that's working and contacted the Promethean panel company directly and once they checked everything they reckon the problem is with the computer and I need to get the graphic card or the port chipset checked. Can someone please help me as I'm lost and I can't display my screen to teach the kids. 

Many thanks,
