After uncommenting  disable overscan 1 follow my lead  In the link  http   elinux org RPiconfig when you search for Video options  you ll also get hdmi group and hdmi mode  For  hdmi group choose 1 if you re using you TV as an video output or choose 2 for monitors  Then in hdmi mode  you can select the resolution you want from the list   I chose  - hdmi group 2 hdmi mode 23 And it worked
