The screen flashes/blanks randomly, when It flashes, It goes blank and stays in blank for like 2 seconds and screen comes back again. But again after having 1 second of screen, it goes blank again. Sometimes it might take up to 10 minutes for it to go blank, but sometimes every 2 seconds it goes blank. I've tested using a 1280x768 monitor and it worked fine without even one blanking. I'm using a HDMI to VGA converter. My own monitor is 1048x768 LG Flatron old monitor. Could that be my monitor is taking some power from raspberry? But if it's taking power, then why does the monitor go blank randomly and why sometimes it works for 10 minutes without blanking?
Also as a note, I've tried
hdmi-safe and it was the same. I tried changing the resolution but it was still the same problem.
