For some strange reason, I can't answer this question - it hangs everytime I try to post an answer, but just for this question, no others. So here's my answer:

See this code to turn off the warning:

% Turn off this warning "Warning: Image is too big to fit on screen; displaying at 33% "
% To set the warning state, you must first know the message identifier for the one warning you want to enable. 
% Query the last warning to acquire the identifier.  For example: 
% warnStruct = warning('query', 'last');
% messageID = warnStruct.identifier
% messageID =
%    Images:initSize:adjustingMag
warning('off', 'Images:initSize:adjustingMag');

When you say "i want to sort out this problem not to suppress", the only way to not have a warning (without suppressing the warning so that it does not appear in the command window) is to not display an image bigger than the screen. So you could subsample or use imresize() to create a smaller, temporary image. But that is totally unnecessary and time consuming , plus you'd just be doing explicitly yourself what imshow() does internally anyway . So the only sensible option is to suppress the warning, and I gave you code for that.
