@mitu It was commented out in my /boot/config.txt file. I uncommented it, but it had no effect. Here is my current config.txt file:
# For more options and information see
# Some settings may impact device functionality. See link above for details
# uncomment if you get no picture on HDMI for a default "safe" mode
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
# uncomment to force a console size. By default it will be display's size minus
# uncomment if hdmi display is not detected and composite is being output
# uncomment to force a specific HDMI mode (this will force VGA)
# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
# uncomment for composite PAL
#uncomment to overclock the arm. 700 MHz is the default.
# Uncomment some or all of these to enable the optional hardware interfaces
# Uncomment this to enable infrared communication.
# Additional overlays and parameters are documented /boot/overlays/README
# Enable audio (loads snd_bcm2835)
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
I should add that after uncommenting overscan_scale=1, I also tried uncommenting overscan_left and setting it to -16. It also had no effect.
i had something similar happen with my roku / TV .... LG pushed out some sortof update that didnt work well with roku.. i had to connect to another TV memorize the key strokes to set the resolution to a lower resolution. It worked fine after that ... dont know if i ever increased the resolution again.
Possibly adjust resolution lower and see if that resolves the problem.
Sorry I forgot to paste this in on my previous post.

Hi, I had a similar problem. It appears I have solved it by forcing the monitor to use HDMI input in the settings as opposed to autodetect. Hope this helps people encountering this issue in the future ;D
