HDMI connection from P2 not recognized by TV

Rayman

I think there was a discussion about something like this before, but I couldn't find it...

Tried to connect P2 to brand new TV and it won't recognize the signal.
This is the TV: https://www.bestbuy.com/site/insignia-32-class-led-720p-smart-hdtv-fire-tv-edition/6247254.p?skuId=6247254

I've tried several computer monitors and they all work as expected.

I also tested with an HDMI switch and it doesn't quite work right either.
Interestingly, if I connect the signal to switch input #1 and disconnect all other inputs, it will send signal through to a projector...
But, I can't select that input with the button if other things are also connected to the switch.

So, I think the TV must be looking for something that my P2 board is not providing.
Maybe it's the 5V signal? I tried giving it 5V using a resistor, but that didn't work. Maybe not enough current...

Any ideas? I think there's also an I2C connection. Maybe this is required by some devices?

In one of my threads, I was shown how to bring up the-5 volt signal by Tubular.

Many TVs need it.

I will search

Plz add this to HDMI experiences thread.

The picture showing the connection is there.

Hopefully adding that 5v signal does the trick

If it doesn't, the other trick Rogloh put me onto was using 720x480 video at 270 MHz, rather than 640x480 at 252 MHz
