The ProScreen 4750 is a LED-LCD projector by Philips, whose specifications list 750 ANSI lumens, a contrast of 150:1 and a XGA 1024 x 768 resolution. In operating mode, the installed projector lamp offers a lifespan of 4000 hours, achieving a lifespan of 5.5 years when used for 2 hours a day. Looking at practical performance, up to 238 cm can be illuminated with 750 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 159 cm. The model is currently no longer actively offered on the market by the manufacturer.

There‘s really nothing you can do about it.
This is also a common problem with the 4600.
Have these stripes or shifts with the 4600 and 4750.
There‘s only one thing to do: garbage can it!
