OK, the 8400GS driver is the latest - no signal to the TV using HDMI or Display from the MB ports. The 12 year old card worked great on HDMI and my TV and a 12 year old AMD Athlon processor. Then my PC got fried by lightning and I had to replace the MB and processor. New MB Port Display adapter to HDMI cable also did not work - no indicated signal to TV? TV works on HDMI with another laptop - and the laptop is about 15 years old. So 12 years later, I can not use HDMI on my new ASUS B550 MD and new AMD processor. This is just crazy.
Is there any way to use HDMI from this MB and processor? What happened to technically advancement over 12 years?
