ARpiCADE Forums

Hey All,

Any help adjusting the overscan on Arpicade this would be great. Auto adjust isn't running on startup on my Dell VGA monitor for some reason (it does on my 60-1 board and Retropie image no problem with no overscan). And I can't get to the monitor controls without taking the whole unit apart (it was glued and screwed by the original vendor).

I also tried messing with he overscan settings in config.txt a bit, but to no avail.

It's like this on the Arpicade menu as well and all games.

Thanks!

High res screen?

You may have set high res in config.txt and not commented out the overscan settings in same file. Otherwise if that's not it let me know and I'll try to figure it out.

Yes, it is a high-res screen.

Current config settings:

# uncomment the following to adjust overscan / picture position. Use positive
# numbers if console goes off screen, and negative if there is too much border
# also use overscan_scale so the emulators comply & still use disable_overscan
# do not adjust top and bottom or you will loose scanline perfect output although
# you can move the picture up or down evenly with okay-ish results better not to
# overscan_left=14
# overscan_right=14
# overscan_top=11
# overscan_bottom=14

# ignore edid - we just want video output to do as we say anyway
hdmi_ignore_edid=0xa5000080

# force hdmi output
hdmi_force_hotplug=1

# uncomment to force a HDMI mode rather than DVI so audio works
hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
config_hdmi_boost=6

# use full spectrum RGB over HDMI
hdmi_pixel_encoding=2

## PLEASE NOTE: due to the resolution switching launcher scripts changes made
## in this section are at your own risk, 480i is default for this build
# Use group 1, only change the mode. For Group 1 Mode 8 is 720x240,
# Mode 6 is 720x480i & Mode 1 is 640x480p. Any mode except 1, 6 and 8
# may have unexpected behaviour (see /boot/launchers/resSwitch.sh)
hdmi_group=1
## Use only one mode at a time
# Boot and menus in 480i (rotated games in 480i, non rotated games in 240p/256p/288p)
#hdmi_mode=1
# Boot and menus in 240p (all games in 240p/256p/288p)
hdmi_mode=1
# Boot and menus in 480p (no res switching, just 480p)
#hdmi_mode=1

That looks fine. If you could get to the monitor control board that would be the best way to fix it. As you can't you may as well try adjusting the left and right overscan in config.txt (your monitor is rotated so you want left and right in file for top and bottom of your view of the monitor)

Not sure which way the monitor is up so you may have to try moving the pic either way by making one positive and one negative. eg

overscan_left=14
overscan_right=-14

don't forget to remove the # before the two lines so they are used. You may need numbers other than 14, it's just an example. If you keep both numbers the same (with one negative) it should avoid causing image degradation and just move the picture over, at least I think so I haven't had to try this on high res before...

I tried multiple numbers and leaving one line and both lines, but no adjustments happened at all...

I just had a play on a high res monitor. The overscan settings should definately move the picture. Negative numbers had no effect on my monitor as it was already lined up with the edge but positive brought the picture in when used.

Perhapps post your config.txt again in case something is wrong. Or maybe try higher numbers as 14 pixels isn't much, maybe you just didn't notice the change...

Hard to say for sure what is happening. It is a shame you cannot access the monitor controls.
