I've worked through the wiki and got the side black bars to go away but the top and bottom bars remaine...
I'm using a TV and HDMI cable. It seems like the screen resolution is off. It's cutting the image off at the top and the bottom. Using overscan_top and overscan_bottom pushes the text under the black bars. It doesn't move the bar up or down.
Settings I've uncommented:
hdmi_group=1
hdmi_mode=4
disable_overscan=1
overscan_left=50
overscan_right=50
overscan_top=-50
overscan_bottom=-50
I've spent hours on this and can get the top and bottom bars to go away, any ideas?
