They don't need to change it. The denomination is now in the lower left corner of the VIDEO screen.
It's glued to the inner glass (there is an inner glass and then the touch screen; sandwiched together on the monitor "assembly"). As you can see, it's part of the graphic - no denomination window anymore. If you order the part number in the picture, you get the inner glass only.
Here's a photo of the graphic insert after it was removed from a broken glass with a heat gun and then the glue cleaned off it by brake cleaner:
Hope this helps....
