What is the solution for miniature VGA monitor. 3.5, 4.3, 7 inches. with the lowest price?
Needed to control the parameters on a regular computer, but not to rush around with an extra monitor and not take up space.

Answer 1

There is such a thing: clck.ru/8bCtt , though not VGA, but USB. Old article on Habré: clck.ru/8bCtx

Answer 2

If satisfied with a 2.8 inch TFT LCD display, then I found an interesting project earlier:
USB LCD - LCD System info : Project .
Here is a video on YouTube-e: Video .
there are two lots on eBay: 1= $28 , 2= $34 .

Answer 3

I suspect that it might be cheaper to find some kind of car monitor with RCA for the required number of lines and get confused by connecting it to a computer (more recently, S-Video was also made on video cards =)
If you dream up, you can think of buying a cheap smartphone with a screen of 3, 5 * and use it as an additional monitor.
