Any tutorials available for this?

For my application, HDMI splitter will not work. I am making a portable solution. It has to be wired together and not by a bully splitter. – ironmantis7x Feb 14 '19 at 6:01

@ironmantis7x Perhaps you should explain in your question what exactly you want to achieve. It may turn out you don't even need to connect two RPis to one screen. – Dmitry Grigoryev Feb 14 '19 at 16:13

@ironmantis7x Your question says you have 2 RPis and 1 LCD. Your comment says you have 2 LCDs. Which one is it? – Dmitry Grigoryev Feb 15 '19 at 10:04
