So, im new to the raspberry pi. When i first started it and installed the raspian os with noobs, it had fine resolution. But then i rebooted, and for some reason the noobs menu was in alright resolution but when raspbian os started up it hat a really small resolution that was way behind the maximum of my TV! I am plugged in trough a HDMI cable on my TV that has a resolution a bit better than 720p resolution. Anyone knows whats happening?
Ok, so i have disabled overscan in the raspberry pi configuration menu and now it works!
