      If screen mesh has UV simply use UV mode.

        How to do it UV mode? UV form Image file or from UV/Image editor?

          Go to the UV editing mode in Blender, and adjust your UV mapping as needed. (Right now you have to change renderer to Blender or cycles to see the texture show up in the viewport.) Once you have the image adjusted where you need it, change the Mapping settings to "UV"
          If you want to have dark bands above and below the image and you don't want to fiddle with decal settings, you may need to split up the faces of the projector screen and map a blank screen color above and below.

            So I have. My photo in projector screen have 1920x1080 and I can not place to in full size as original image (see render result). Scal with transform das not produce result.

              You don't need the transform node if you've correctly mapped your texture in Blender.

                Here's a really quick sample of what I mean. Blend file attached in the zip archive.

                    Until you adjust the UV mapping in Blender, it will keep cropping your image.

                        In your screenshot it looks like you still have "projected" mode selected in the image file node mapping settings. Try changing that to "UV"

                            Take a look at my test file a few posts up: https://forums.chaosgroup.com/filedata/fetch?id=966597
                            You'll need to split up the face of the projector screen and rotate and rescale the UV until it fits. (If you want to see the openGL view of the textures, you'll have to switch your render engine to "Blender" from "Vray" because textures don't show up in the viewport with Vray selected.)
