My computer screen is ATVIO brand, but when I used another screen (Samsung) the OS works fine, can someone help me?
I've had these problems before. What I had to do is that I connected a screen which was compatible, I lowered the resolution to 800x600, and then I connected my first screen.

You could also try another type of graphical connection (eg. HDMI/DVI instead of VGA).
