I set screen res to 800×600 using settings etc. then set it back and colour to 16 when I later had gpfs bootings me out of programs. Now colour resets back to 16 when I change it to 256 or 16 bit, also slider wont change screen area now. Why? and the advanced dialogue box seems to have changed. How why? How do I get colours back? What d I need to reinstal? and how?
