26-28 inch 1080P smart flat screen TV with audio output

The audio out can be a headphone jack. That’s what I’m using now out of my 32 to my surround sound amp.

I wanted four HDMI in and found that the 720 cheapy sets have less inputs and often lacked the output.

The 1080i set for a few more bucks will give you a better picture.
If you use Blu-ray esp.

You don’t need a 12 v set. Use a 300w inverter.
