I'm modeling a iMac. I did UV mapping for the in screen image and applied image texture to the screen. Everything looks fine on viewport. But when I render the image in the texture shrunk.

I have tried, removing the edges and adding them back in. I have tried creating new texture. Adding new image. Moving the mesh to a clean file. Nothing works.
