Hi Naveen

For the behavior you want there is a attribute please have a look at
Presentation Pixel Magnification Ratio (0x0070, 0103). You can use it
with Pixel size mode "MAGNIFY".
Have a look in part 3.

I hope it helps.

Thanks Bimalendu for your reply..
But I still have some doubts, the above mentioned will work only if
display window size in high resolution and low resolution monitor
contains same number of pixels isn't it? Is there any way to ensure
the same area is displayed even if the no. of pixels in the display
window of the low resolution monitor is less than that of the gigh
resolution monitor.
