Hi


I am new on here so not sure which forum will best help me. I used a keyboard shortcut to change the display on my sony vaio laptop. Found it on a web forum. It was used to make viewing video downloads better quality.


it was something like cntrl upper case and f12 and then you pressed the same keys to revert back to original display. I have now forgotten the combination and my display is stuck in a lower resolution and has a purple and white display on my desktop.


cntrl alt and f12 just brings ups the intel graphics box. can anyone help? I have been told I will need to do a refresh if I cant find the answer and I want to avoid this.

Can change display setting using "Display" on control panel.

Go To: Control Panel\Appearance and Personalization\Display

to try and explain further the shortcut I believe use the alt+shift+f12 this change my normal screen to a shades of purple and white background but improved viewing of videos.


I pressed the same combination and my display returned to normal. I did not change it back to normal after the last change and I have now forgotten the combination. I have tried the normal routes to change the display but all looks normal. A technical helpdesk had not heard of this shortcut and thought I would need a refresh to reset my lap top.
