I think you missed the original post. He wants to project the image 
from the LCD monitor onto a a photo resist PCB so he doesn't have to 
make a negative, and he wants to achieve better than 1200 DPI on the 
board. The largest he could do with the monitor you mention is a ~ 
1" board, not a 4x5 (assuming it would even work ofcourse).
