200x140cm @ 300DPI is 372Mpix.... completely unrealistic. At normal 
viewing distance the average human eye doesn't see any detail smaller 
than 1/1800 of the diagonal (which means a 6Mpix image is normally 
enough, whatever the physical print size) . 300DPI is also going to be 
finer than the canvas...

How big is your current image (in pixels, since that's the only thing 
that counts)?
