Digital Controller
"I can build a digital VGA controller so you can use my laptop LCD as a monitor for my desktop PC?
I PC LCD laptop I use as a monitor for my desktop computer. I need to convert, however, analog VGA signal to digital PC to run LCD screen. I read somewhere that I can do with an FPGA using VHDL. I just want to know what program because If I do not understand very well how to convert successfully.
VGA is analog. Therefore, you need to build an analog digital. You will need to quantify the analog voltage to obtain a digital representation. Once I had, you want to build the digital signal. I have not compared the VGA and DVI specifications, but you may need to use multirate sampling technique to match the analog and digital resolution, see the first link in the sources, Chapter 4. big question for you, however. This project is not trivial. If you do just for fun, why not buy a ready-made business solutions. See second link sources.
