I use a Dell M109S (not pico but quite small) and as long as you’re in the dark it works fine.
Basically you need to ask yourself these questions :
How big do you want your screen to be ?
Where do you plan on using it ?
thanks to all, happy to see french here ( on peut s’aider si vous désirez )
i want a screen minimum 32” and , low cost, its for me and iam the only user and i dont want to use it in total dark ...
