I've just purchased a Raspberry Pi Model B, I've installed NOOBS latest version after I've formatted card with SD card formatter. Problem is when I'm booting it appears the menu to install Raspbian, but after 2 seconds my monitor (Benq 17" or 18" almost square display) start blinking it goes black after 1 second it appears menu for installing Raspbian and after 2-3 cycles it doesn't show anything.
I am using an HDMI to VGA adapter.
