Heller everyone! I have been looking through the forums and the internet and can't seem to find a clear solution to my problem. I would like to have 2 monitors for the raspberry pi 3, preferably through RCA. I believe I will either have to use the HDMI and RCA ports already on the pi and convert the HDMI to RCA with an adapter, or somehow get another RCA output over the GPIO's. I am using this monocular: https://www.aliexpress.com/i/32832774163.html and an ancient screen from a soon-to-be-cannibalized car dvd player (it looks like this: https://www.walmart.com/ip/Venturer-Car ... rs/4756575 , but it's about 14 years old now and I only have the main hub player, the alternate display was destroyed). I have been considering buying a rpi 4 and converting the HDMI mini outputs to rca, but then I would need 2 adapters and that would be bulky and messy.
I plan on having the pi desktop visible through the monocular and a pygame window running on the larger TV monitor.
Is this feasible or am I just being an idiot? Will I need to buy a rpi 4? Thank you for reading this post, please reply if you have any thoughts that may help!
