Few weeks ago had to connect a projector (beemer) to the computer (Intel Core I3) and after that day, the resolution of my screen is changing suddenly, several times a day...the screen gets black and suddenly the shape of desktop is smaller, then appears a message saying something like "Notification about optimal resolution..." (but when I click on it, it makes nothing) and actually the resolution I have is the "optimal" or "suggested" one by the system. After few seconds, it changes again to the original shape...but it´s quite annoying as you cannot control it and it interrupts what you are doing or writing in that moment.
I couldn´t find any solution to it in the FAQS, that´s whay I ask about it here...
THANKS A LOT IN ADVANCE!
We recommend having the latest graphics drivers and latest BIOS update for the motherboard. Check for any conflicts in device manager and test with a different monitor if possible to narrow the issue properly.
