I have tried several solutions to the pi in the field problem. I have a dedicated "Field Pi" all set up with the right connections and I can the connect via VNC from my laptop, just like I do on my home setup. It all works well, when it works well. However when there is a problem on the Pi and I cannot connect , the only way to diagnose is by connecting a screen/keyboard and mouse to the Pi. This is in effect a full PC set up. So I think the problem is mis stated. It should not be, how do I connect a screen to a field Pi, but rather what kit do I need in the field.
One solution is the PC/pi free route eg smart mount, DSLR local storage, it works its simple and its light, but you loose all sorts of useful features,
If you want INDI/EKOs in the field, then you need a processor, a keyboard/mouse and some sort of screen to see what is going on. Indi/Ekos is very resource light and therefore the obvious solution is not a Pi but a cheap laptop running Ubuntu. I have loaded The Ubuntu version of INDI/EKOs and its easy, there are excellent instructions here: Ubuntu Instructions .

Before this revelation I would take my Pi and travel gear on vacation to a dark sky and spend half my time trying to fix problems. Now laptop based its much more straight forward.
