How to factory reset PS3

[Benjycool]

Hey friends, I have just got my new sony playstation 3 few days ago, so i don't know its all functions properly. My monitor is not giving the proper resolution. Do you know how can i restore the factory settings to default ?

Not proper resolution is the issue to solve with your monitor not with the ps3 settings, there are settings for video also but first check for the settings done in you monitor. Look for the color and resolution settings buttons on your monitor.

Perform the following steps:

• First Switch off the PS3 via the power switch on back and power back on switch.
  
• Now Hold Power Button on the Front until you hear 3 beeps.
  
• Then go through the initial setup and then run a full Format via System -> Format. It will take hours . You may need AV cables if your using HDMI, if the HDMI doesn't detected after initial reset.
  
• Restore your backup you made prior to doing factory/hard reset , f backup is created.

First try this, HOLD your PS3 Power on button for 5 seconds and after the second beep release it. It should automatically configure your playstation 3 to your Monitor's resolution for all settings.
