Well what kind of resolution does your LCD/Display system have? I 
think to get better than 1200 dpi on your 4x5 board you are going to 
need display driver that supports atleast 6000x4800 pixels, and a 
LCD that can display them at a managable size. 

I have been developing photos in my home darkroom for 20 years or 
so, and I'm not really clear on how you plan to accurately focus 
when the board is in the negative carrier of a normal enlarger. I 
have always used a grain focuser when making prints, but you 
obviously cant do that if your trying to image onto the negative. 
Focus can be very fussy and easily affected by very slight 
movements. Removing the negative carrier usually requires me to 
refocus.

Good luck with your project.
